How Does Custom Aluminum Extrusions And Custom Drawn Aluminum Compare?

Among the aluminum products, you can opt for custom aluminum extrusions or drawn aluminum extrusions.

Here is a comparison between the custom aluminum extrusion and the custom drawn aluminum.

Custom Aluminum Extrusions

Aluminum profile extrusion

Aluminum extrusion profiles

You will make custom aluminum extrusion by heating aluminum alloys and forcing it through a die.

At the other end of the die, you will obtain the final product from the heated aluminum alloy.

You must also understand that the shape of the extrusion die will determine the final shape of the extrusion.

Custom Drawn Aluminum

You will make the custom drawn aluminum by pushing the heated aluminum alloys into a mould.

The mold stretches out the heated aluminum alloys thus undergoing plastic deformation.

You can use this process to make aluminum products such as pots, cans, among other circular objects.

Why Is 6XXX Series Alloys The Best For Structural Custom Aluminum Extrusions?

You can choose from a long or extended list of aluminum alloys with different tempers.

In construction and building applications, you should consider using the 6XXX series.

It is the most suitable aluminum alloy with the most convenient characteristics for building and construction.

In this case, the main alloys that you will consider using are 6060, 6063, 6061, and 6005A.

In case you are looking for aesthetical value, you should the 6060 alloys and 6063 aluminum alloys.

You will also use the 6061 aluminum alloys and 6005A aluminum alloys for the purpose of construction.

The 6XXX series offers you greater strength, proper electrical conductivity, as well as other functional benefits.

What Production Steps Are Involved In Custom Aluminum Extrusion Process?

The main process of producing aluminum extrusions is through the extrusion of aluminum alloys.

To properly understand the whole process, here are the main steps to follow during the extrusion of aluminum alloys.

1. Design the Custom Aluminum Extrusion

First, you must have the design of the custom aluminum extrusion that you would like to have.

You must have the design of the custom aluminum extrusion according to the demands of the client.

Apart from that, you will also create a die which mimics the exact cross-section of the final product design.

As soon as you complete the design, you should share it with your client on a CAD file to confirm the design.

You may also have a 3D printer to produce the exact design that your client needs.

2. Die Cutting

As soon as your client approves of the die design and drawing, you will produce the die.

You will cut the die in order to produce an off tool or initial sample.

After that, you will use the sample to check the measurements as well as the production processes.

In addition to that, you must also conduct fine tuning ion order to get the most preferred specifications.

3. Production or Extrusion Process

As soon as the off-tool sample is ready and approved, you will proceed with the production process.

You will heat and load billets or blocks of aluminum alloys into the extrusion press.

After that, you will apply pressure which will push the heated aluminum billet through the die.

On the other hand of the extrusion die, the desired shape will emerge before cutting it to length.

After that, you will tamper the extruded aluminum with heat and the increase the strength by stretching.

4. Value Addition

These are the final stages of the extrusion process where you will complete the fabrication and extrusion process.

Some of the finishing touches you can have on the custom aluminum extrusion are anodizing, and powder coating among others.

Apart from that, you can proceed with further fabrication such as punching holes, cutting and drilling among others.

You can also add thermal breaks before packaging and distributing to different locations.

Do Custom Aluminum Extrusions Require Additional Finishing?

No, you do not need to have additional finishing on the custom aluminum extrusions.

As soon as extrusion is complete, the custom aluminum extrusions naturally form tenacious oxide films to prevent them from corrosion.

You will only need the additional finishing for aesthetic reasons as well as severe service conditions.

In most cases, your client will specify the most suitable type of surface finish for custom aluminum extrusions.

Which Are The Modern Extrusion Processes Used In Custom Aluminum Extrusions Manufacturing?

In the extrusion of aluminum, there are different processes that you may opt for.

There are two most recent extrusion processes that you can have for your custom aluminum extrusions.

Here are the two main types of modern extrusion processes for aluminum.

Friction Extrusion

Illustration of friction extrusion

Illustration of friction extrusion

You may use friction extrusion which involves automatic rotation of aluminum billets by looking at die position.

As the die rotates, it leads to the production of heat through friction at the entry point of the die.

The presence of heat allows for the extrusions to flow through the die easily.

Micro Extrusion

Micro extrusion

Micro extrusion

You can also create micro-sized and small objects by using the micro-extrusion process.

It is a very technical process that requires a lot of concentration and resources thus decreasing its popularity.

What Parameters Influence The Wall Thickness Of Custom Aluminum Extrusions?

One of the most important things that you have to look at when considering extrusion strength is wall thickness.

Apart from that, you must also look at the cost efficiency among other factors when looking at wall thickness.

Here are the main parameters that will influence the wall thickness of the custom aluminum extrusions.

  • Choice of Aluminum Alloy
  • Shape of the custom aluminum profile
  • Extrusion press speed and power
  • Final Surface Treatment

What Is The Recommended Wall Thickness Of Custom Aluminum Extrusions?

Thickness of aluminum extrusions profile

Thickness of aluminum extrusion profile

When looking at the most suitable wall thickness for the aluminum extrusion, there are factors to consider.

Among the factors to consider are strength as well as optimum cost efficiency for a better wall thickness.

Implying that, there are no specific wall thickness that you must have on your custom aluminum extrusion.

You can easily determine the most appropriate wall thickness that will suit your application specifications.

Apart from that, you can also have varying wall thickness for your custom aluminum extrusions.

Do You Offer Services In Prototyping Of Custom Aluminum Extrusions?

Absolutely, we offer services in prototyping of the custom aluminum extrusions.

Before we make the final custom aluminum extrusion, we often produce the prototype.

As soon as the prototype is complete, we will send it to the client for approval.

The client must make sure that the prototype is according to the production specifications before we proceed with production.

How Many Tempers Of Custom Aluminum Extrusions Can You Choose From?

The tempers of the custom aluminum extrusions are an indication of the class of treatment and basic operations.

Here are the main types of tempers that you can use with the custom aluminum extrusions.

F Temper (AS Fabricated)

In this forming process, you will not need special control over strain or thermal hardening conditions.

O – Temper (Annealed)

In this case, you will have to heat the products to produce lowest strength to improve dimensional stability and ductility.

H – Temper (Strain Hardened)

You will apply this temper to products which you will strengthen through the cold hardening process.

You may follow it with supplementary thermal treatment which may reduce strength.

W – Temper (Solution Heat Treated)

This is an unstable temper that you will apply to alloys that age spontaneously at the room temperature.

This will happen as soon as the process of solution heat treatment is complete.

T – Temper (Thermally Treated)

You will apply this temper to heat treated alloys with supplementary strain hardening for a stable temper.

You can get T4, T5 or T6.
