• Better resistance to atmospheric corrosion
• Excellent machining properties

Well, as you can see, these are the key grades of aluminum rectangular tubes you’re likely to find in the market.

As a rule of thumb, before you buy any grade of aluminum rectangular tubing, know the type of applications first. Secondly, understand the environment where you intend to use the extruded aluminum tube.

Of course, discussing all these with your aluminum tubing manufacturer will make it easier to get a suitable accessory.

Manufacturing Process of Aluminum Rectangular Tube

Once you have the right aluminum tubing extrusion machine, the process remains simple and straight forward.

Also, before you begin the process, it is important to test the quality of the aluminum grade.

Here is how the extrusion of aluminum rectangular tube works:

Step 1: Cut billet to the right size and heat to a suitable extrusion temperature. It may range between 800 and 925° F, depending on the aluminum grade.

Step 2: Transfer the billet to the loading area, then add a parting agent to prevent possible sticking of the billet during aluminum tube extrusion process. The extrusion machine will then apply pressure on the billet, putting in the right position ready for extrusion.

Step 3: The aluminum billet is then pushed against the die. Here the dies have the shape of an aluminum rectangular tube you need.

To prevent the die from overheating and oxides from forming, you’ll add liquid nitrogen.

Step 4: As you extrude aluminum rectangular tubing, take note of the exiting temperature. It will help you to maintain the extrusion speed.

Remember, different grades of aluminum have varying exiting temperature. For instance:

• For alloys 6063 aluminum alloy, the minimum temperature is 930° F
• In the case of 6061 aluminum alloy, the minimum temperature is 950° F

Step 5: Extruded aluminum rectangular tubing leaves the die, cools, and cut to an appropriate length.

Depending on the specific requirements, you can take through various finishing operations such as polishing, painting, etc.

Fabricating Aluminum Rectangular Tubing

Machining and fabrication is an important part of any metalwork process.

The best part, you can easily machine or fabricate aluminum rectangular tubing to meet your unique application requirements.

Here are some of the most common procedures:
