Large Diameter Seamless Aluminum Tubes FAQ

Here are most of the questions related to large diameter aluminum seamless tubes. We hope you will find the answer to your question. If not, please leave us a message.

2024 Aluminum vs. 7075 Aluminum2023-09-13T07:58:38+00:00

If you are unsure which option between 2024 and 7075 aluminum is better, it is understandable. Both alloys are known for their high strength, so they could suit a project if that is the sole consideration.

But when it comes to specifics, things begin to change. For instance, if you are looking for an alloy with higher stress/stain resistance, then we would recommend the 7075 aluminum. However, use 2024 aluminum if the cyclic fatigue resistance requirements for your project are high.

The 2024 aluminum is mainly composed of aluminum, copper and magnesium. The 7075 aluminum is mainly composed of aluminum, zinc and copper.

They are all hard alloy, and widely used in aircraft parts. But the 2024 aluminum is not common for general industries.

Can I use 6061T6 instead of 7075T6?2023-02-28T03:35:14+00:00

Different aluminum alloy and temper is with different mechanical properties, as well as different requirement in application. Click How to Choose Aluminium Profiles: 7075T6 VS 6061T6 to see the differences of 6061T6 and 7075T6, which can help you to confirm the material that you need for production.


What is the max. width you can extrude?2023-12-05T03:13:45+00:00

The max. width that we can do depends on the exact profile shape. Please send us your CAD drawings for a brief check firstly.

The wider the cross-section, the larger the extrusion press is needed. Our largest capability is with width 750mm for some shapes. Many construction companies will be concerned about the maximum width that an aluminum extruder can do. For example, the width of the aluminum formwork usually needs to be at least 300mm.

In cooperation with top institutions in China, we offer and produce aluminum extrusions with a maximum section width of 1100mm. We are working with many famous transportation companies on large size aluminum extrusions.

Can you provide machining service for extrusion order?2023-05-04T04:13:17+00:00

We have an aluminum fabrication shop to provide CNC machining and fabrication service.
The material is not only aluminum extrusion products but also aluminum sheet panels. Please send us your CAD and 3D drawings for a quote.
