FONNOV 7075 Aluminum Extrusions For Our Customers
▹Custom 7075 Aluminum Extrusions
7075 aluminum alloy is super hard, but it can still be extruded. 7075T6 is common extrusion products. 7075 T6 aluminum has good plasticity after solution treatment and has excellent heat treatment strengthening effect. It has high strength below 150 degrees and has particularly useful low-temperature strength, poor weldability, stress corrosion cracking tendency, and double aging can improve anti-SCC performance. It has lower resistance to corrosion than many other aluminum alloys but has significantly better corrosion resistance than the 2xxx (2024, 2A12) alloys. Its relatively high cost limits its use, and its extrusion is also harder in production compared with other aluminium alloys.

7075 Aluminum Extrusions FAQ
Here are most of the questions related to 7075 aluminum extrusions. We hope you will find the answer to your question. If not, please leave us a message.
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.

7075 aluminum extrusion is a zinc-magnesium-copper alloyed aluminum product, and it is produced by an extrusion process.
Generally, 7075 aluminum extrusion products are used in the aerospace and defense industry because of their superior strength. 7075 aluminum alloy is considered one of the highest-strength aluminum alloys. Aluminum is lightweight than steel. So the strength-to-weight ratio of 7075 aluminum extrusion is excellent, and this is the reason that it is ideally suited for high-stressed aircraft parts with light weight.
The 7075 aluminum extrusion products include custom 7075 aluminum extrusion profiles as per drawings, 7075 aluminum rods, 7075 aluminum bars, 7075 aluminum tubes and pipes, 7075 aluminum round tubes, 7075 aluminum square tubes, 7075 aluminum angles, 7075 aluminum channels, 7075 aluminum beams, 7075 aluminum rails, etc. FONNOV ALUMINIUM can produce 7075 aluminum extrusions with solid shapes and hollow shapes.
