Aluminum Extrusion: The Ultimate Guide

Aluminum Extrusion is forcing solid aluminum billet through a shaped die，which gives aluminum its unique shape.

The extruded aluminum comes out as an elongated piece. This piece has the same profile as the die opening. Aluminum billet needs a good deal of pressure to help it pass through the die.

What is Aluminum Extrusion?

Definition of Aluminum Extrusion

This process is similar to squeezing toothpaste through a tube.

The process of aluminum extrusion can be clearly understood by having a look at the picture given below.

The given example explains the extrusion process in such a simple way that even a layman can understand it.

There is no doubt that you can see some similarity between the extrusion process and the way Play Dough is made to squeeze through the press.

As you can see from the picture, the Play Dough easily passes through the opening that has a specific die shape.

 Although the above principle also applies to the process of aluminum extrusion, but it is a bit more advanced and complicated .

Aluminum can be extruded by using the direct or indirect extrusion methods, including either the hot or cold extrusion. The most commonly used process for Aluminium Extrusion is the hot extrusion.

The extrusion process used at Wellste is the Direct Extrusion( Hot extrusion). Therefore, we will focus only on this method.

Direct Extrusion (Hot Extruded Process)

It is one of the most commonly used method for producing extruded shapes. you can also refer this process as forward extrusion.

It is a process that hot billet is loaded in the thick-walled container and moves in the same direction as the ram.

The ram of machinery moves and forces the hot billet (semi-finished metal form) through the die.

A dummy block is a steel disc, slightly smaller than the container. It is used to separate the hot billet and the ram, in order to protect it from heat and pressure.

The dummy block is reusable. Lubricants are widely used in order to reduce friction and provide protection to the die surfaces. Graphite is commonly used as a lubricant.

The actual process of extrusion starts when the ram applies pressure to the billet.

The billet is crushed against the die, pressure is applied. The billet need more extrusion force than required in the indirect extrusion process. This is because the billet needs to move the entire length of the container.

Therefore, the greatest force is usually required at the start of the process. The pressure eventually decreases slowly as the billet is used up.

As a result of the applied force, the billet becomes shorter and wider. When the pressure is increased, there will be no space left for the soft aluminum billet.

This will eventually force the billet out through the shaped die. The billet emerges from the other side in the form of a completely shaped profile.

The shaped profile are then sent to be cut off into smaller shapes.

Aluminum Extrusion Manufacturing Process Flow

Step 1: Tooling,

Aluminum extrusion die can be made into any specific or required profile with the help of tooling. The extrusion is usually made up of H13 steel.

The shape of the die opening is same as that of its required shape. Every profile made only by its own unique tooling.

The first step involves the creation of the required die with its specific design, The design and manufacture of extrusion dies is a highly specialized procedure that requires skilled die makers.

Step 2:  Aluminum Billet Preheating,

Aluminium extrusions are made from solid aluminium cylinders called billets. Aluminum billet is cut to required length based on product specifications. The billet is heated to about 800°F-925°F.

Step 3: Extrusion,

After heating, The heated billet is then placed into the cradle. Substantial pressure about 500-700 MPa is applied with the help of a ram. The billet is forced through these dies.

Step 4: Maintaining temperature,

With the extrusion process being dependant on heat, it is extremely important to maintain a consistent temperature throughout this process.

It is extremely critical that the temperature is carefully monitored from the beginning of the process till the end. This step will ensure that the alloy properties like tensile strength and yield strengths are met.

Step 5: Cooling,

The extruded aluminum profile comes out as an elongated piece that has an exact shape as that of the die opening, and then cooling is the key for the stretching process.

The extruded pieces can be cooled either with water, air or both, It is finally pulled to the cooling table, and then fans are responsible for cooling.

Aluminum extrusion must cool at a specified rate, Temperatures should be measured many times in order to ensure alloy properties met.

Step 6: Stretching and Cutting,

A gripper is used on both ends of the extruded pieces. This stretches the piece until completely straight, then the stretched pieces are cut to normal length (approx. 6.0-9.0 meters).

Step 7: Aging,

In the final step, the extrusion pieces are aged. This means they are treated with heat in age ovens. The extrusion pieces are heated up to 350 degrees Fahrenheit for a minimum of 4 hours. This process further hardens the aluminum. Aged extrusions can then be sold directly. The aged extrusions can also be sent to pass through fabrication and finishing processes.

Raw Material for Aluminum Extrusion

It is important to understand here that Aluminum ingot and Aluminum billet are both interrelated.

Aluminium ingot will be formed from raw Aluminium oxide by electrolyzing manufacturing. Aluminum Billets can then be prepared later on from Aluminum ingots.

You can fully understand the manufacture of ingots and billets by the detailed and simple processes given below.

How the Aluminum Ingot is made?

Aluminum ingot is 99.7% pure Aluminum, is also names“A00” Alu. They are in compliance with LME standard.

Aluminium ingots are sourced from casting aluminum manufacturer at wellste. Therefore, we will briefly talk about the manufacture of Aluminium ingots.

Aluminum ingot -Raw material of aluminum extrusions

Step 1:  Aluminium is extracted either from its raw material, bauxite or from scrap recycle Aluminium.

The extracted aluminium metal is melted in a furnace which has a temperature of 800 ͒C. The molten aluminum is transferred to a holding furnace where the metal is casted into ingots.

Step 2: The holding furnace is tilted gradually and the hot, molten Aluminium metal is poured into moulds.

Step 3: The molten Aluminium is cooled by spraying mist water. Make sure that the metal has completely cooled down. It will form the base of your mould. More Aluminium flows into it to fill up remaining space.

Step 4: An Aluminum ingot is formed.

How the Aluminum Billet is made?

 Step 1: Aluminum ingot put into furnace to melting.

You can add various metals like Magnesium, Silicon, and Copper in order to required alloy grades in various series.

Wellste can produces Aluminium alloys of different alloy grade. 6XXX series alloys are most commonly produced for Aluminium extrusion products.

Step 2:  In this process, the smelted Aluminium is casted into billet shapes in a casting mold.

Homogenization is an essential process. It is homogenization of aluminum alloy elements.

It aims to eliminate residual stress and improve workability of aluminum billet. Making cast alloys have both chemical and structural uniformity.

The billet is in a solid form. They are available in a wide variety of alloys.

At Wellste,  Aluminium billets are 6000mm long lengths bar. Therefore, they need to be cut to shorter lengths. The billets can be cut with the help of a saw or a hot shear. These Aluminium billets have a diameter in the range of 60mm to 280mm.

Step 3: The billets can be wrapped and transported to be used in Aluminium extrusion manufacturing process.

Aluminium billets is used as raw material for our Aluminium extrusion plant. It is also supplied as a raw material to a number of other Aluminium extrusion factories.

Aluminum Extrusions Design Guide

Aluminum Extrusions dimensions

Wellste produces aluminium extrusions in a wide range of sizes from small to big extrusions. Aluminum extrusions size can be measured by its cross-sectional dimension. This cross-section fits within the circumscribing circle.

The variety of shapes which can be extruded is endless. However there are a number of factors that need must be considered in aluminum extrusions profile design. These factors are as follows:

• size: The circumscribed circle of a profile determines extrusion press size to extrude.
• shape: The extrudability depends on the cross-sectional shape whether complicate or not.
• aluminium alloy: Controlling alloy composition to avoid affecting Aluminum extrusion profiles surface quality, such as scratch, corrosion and uneven coloring.
• tolerance: Limits of size variations in compliance with GB/T 5237.1 -2008.
• extrusion ratio: The area of aluminum billet/ the area of shape.
• Tongue ratio: width of fin/height, avoid high tongue ratio
• Surface finishes: Different aluminum alloy number has a bit discrepancy in the ends finishing looks.
• assembly consideration: consider the assemblability of finished products

The profiles which are designed without considering these factors will not be extruded successfully.

Aluminum Extrusions wall thickness available from Wellste

Once you have selected the aluminum alloys for extrusion, it’s time to start thinking about wall thickness.

The wall thickness depends on many factors such as the alloy and temper.

Majority of the extrusion plants and aluminum extrusion companies consider the wall dimensions of 0.04” to be thin.

At Wellste, we can carry out aluminum extrusions with 0.02” wall thickness. You can determine the minimum wall thickness that is required to successfully extrude aluminum.

The types of Aluminum Extrusion Die & cost

The types of Aluminum Extrusion Dies:

Aluminum Extrusion dies are highly engineered pieces of tooling.

They can be grouped as solid dies and hollow dies. The solid die produces solid shapes, while the hollow dies produce hollow or semi-hollow shapes.

A single die can be a combination of solid, semi-hollow or hollow shapes.

Solid aluminum extrusions dies:

A solid die usually have one or more apertures. It is through these apertures that the softened alloy can be forced or extruded.

A wide number of apertures in a single die, can be used to produce multiple extrusions simply with each stroke of the press.

Semi-Hollow Dies:

A semi-hollow die usually extrudes a shape that is not only nearly hollow, but also partially encloses a void.

Hollow Dies:

Hollow dies can successfully take up a variety of forms. However, the choice of design and manufacturing methods usually depends on a number of factors such as the profile, size of press and container, and production requirements.

Hollow die – Photo courtesy: aec

Die Costs:

Comparing other manufacturing methods of tooling, The cost to produce aluminum extrusion tooling is inexpensive relatively.

At Wellste, the dies for simple geometric shapes generally cost between USD $220 and USD  $5000.

Cost increases as the circumscribing circle diameter increases. Contact Wellste sales team that offer you fast mold cost within several hours only.

Wellste makes sure that the optimum product performance, quality and cost is achieved.

The Difference of Alloy Temper – Aging

Pure Aluminium is usually alloyed with other elements like copper, magnesium, silicon. As a result, you can find different alloys that have additional strength and unique physical attributes.

In addition to alloy selection, we will discuss alloy temper- aging as well. Aging is the treatment that metal alloy is at elevated or room temperature after quenching. This improve the metal properties of an alloy.

Aging is an important process to improve mechanical properties of aluminum alloy. At the same time, physical and chemical properties improve as well.

you will see a notation next to it such as in the case of T₁ or T₆, that means the type of aluminum alloy temper.

This notation refers to the temper grading of each alloy. In simple words the number alloted to the letter T, describes the treatment that the specific aluminium alloy has received.

When you are in the market to purchase extruded Aluminium, it would be best if you have an extensive knowledge as well as a proper guidance.

You should have a specific knowledge about which range of temper would be most appropriate,

Aluminium alloys are available in a number of different tempers. They are commonly available in two main groups, heat treatable alloys and non-heat treatable alloys.

Non-heat treatable alloys:

These include three types of temper, i.e. F, O and H tempers.

• F Temper :

Free working condition. Mechanical properties of alloys are not specified.

• O Temper:

Annealed, fully soft condition, suitable for processed products that have been fully annealed to obtain the lowest strength.

• H Temper :

Cold-work hardening condition. It is used to get higher strength.

After cold hardening, it maybe followed by additional heat treatment.

Heat treatable alloys:

As the name implies, these alloys achieve their unique strength and mechanical properties by the initial process of heat treatment.

It is then subjected to cooling and finally aging. Temper for aluminum alloys is usually denoted by the letter T.

Natural aging:

T1, T2, T3 and T4 tempers are included this category. This process occurs at an ordinary temperature spontaneously, until the metal reaches a stable condition. This will make the metal hard after heat treatment.

Artificial aging:

T5, T6 and T9 are included in this category. In this process, the metal is heated for a time within the range of 2-30 hours at a low temperature of 100-200ºC.

This process is continued until the metal attains a stable state.

Heat aging machine

This will eventually make the metal hard and increases its strength.

Among these tempers, T4, T5 & T6 are the most common for aluminum extrusion.

T4 is Natural aging to a basically stable condition after solution heated.

T5 is the state being cooled from an elevated temperature forming process then artificial aging.

T6 is the state of artificial aging after solution heat treatment.

Aluminum Extrusion Surface Finishes that Improve Performance

Once you have manufactured the Aluminum extrusion product,it is really important that the extrusion product have a suitable surface finishing option.

The reason is that surface finishing provides an extra protection to Aluminum extrusion, making it highly corrosion resistant and durable.

You can also enhance the appearance of Aluminum extrusion if you choose an appropriate finishing method. Following are the finishing methods available at Wellste:

Anodizing

Anodizing is one of the most commonly used surface treatment methods.

In the anodizing process, a layer of oxidation is added to the Aluminum extrusion products.

This oxidized layer forms the protective layer on the extruded Aluminium. The film is less likely to peel, chip or crack.

Owing to the anodizing process, the properties of Aluminium are not only enhanced, but also provide many beneficial uses.

Advantages of anodizing Aluminium:

1. The protective oxidation layer provides resistance not only against wear and tear but also corrosion. This makes the Aluminum extrusion products quite durable.
2. Anodizing process creates an extrusion product that has an aesthetically pleasing finish, thus providing a clear and smooth appearance. The colour tends to last longer on an anodized surface.
3. Anodized Aluminium tends to have a greater strength.
4. Anodized extruded products require low maintenance and are able to withstand every type of weather.

Electrophoresis:

In this process, two protective layers are formed. The first layer is the protective oxide layer and the other layer is the electrophoretic coating.

Both of these layers provide stain resistance, corrosion resistance and high quality finish.

At first, an oxide layer is added by the electro -chemical method. Then, the anodized Aluminium extrusion is placed in an electrophoresis tank.

This is an electrophoretic painting  process, in which an electricity is passed so that an acrylic resin can adhere to the Aluminium surface.

Usually, the electro-coated aluminum is then placed in another tank for about 30 minutes, having a temperature range of 180-200℃, so that the Aluminium extrusion product can be completely dried.

The Aluminium extrusion products having electrophoretic treatment are extensively used for architectural purposes.

Advantages of Electrophoresis:

• Better performance and durability after electrophoresis treatment than anodized Aluminium extrusion products. This is because the electrophoresis process creates two protective layers.
• The most important advantage of electrophoresis is that it creates a uniform coating for the Aluminium. The thickness of the coating can be controlled simply by adjusting the electricity.
• The electrophoretic coating is both safe and environmental friendly.
• Electrophoresis provide coatings such as high transparent gum resin, which ensure the high decorative effect.
• Electrophoresis-coated aluminium extrusion products are of superior quality, as they are less likely to crack and peel off.

Powder Coating

Powder Coating is to spray powder coatings onto the surface of aluminum extrusion by powder spraying equipment (electrostatic spraying machine).

Under the action of electrostatic force, powder will be evenly adsorbed on the surface and form powder coatings

Advantages of Powder Coating:

• Powder coating produces a high quality and long-lasting protective coating for the Aluminium extrusion products.
• Powder coating is available in a wide range of colours from simple matt, satin and gloss finishes to super matt, super gloss, and textured finishes.
• Dents and cracks can be easily repaired simply by using a liquid coating, which precisely matches original colours. Powder coating tends to have a better colour uniformity between batches.

PVDF

PVDF is yet another process which provides a great finish to the Aluminium extrusion products. It is an electrostatic spraying and liquid spraying method.

The overall performance of a PVDF coating is determined by the fact that the spraying equipment must have an excellent atomizing effect.

This will ensure that the Aluminium surface receives a uniform coating. This will provide a metallic luster and bright colored extrusion product.

Therefore, PVDF coating provides a number of beneficial properties to the Aluminium extrusion products, such as:

• Anti-corrosion
• Anti-frosting
• Anti-fading
• Anti-air pollution
