7075 Aluminum Tube

7075 aluminum alloy is a cold-treated forged alloy with high strength, far superior to mild steel. It is one of the strongest alloys commercially available. A small amount of copper, chromium and other alloys are generally added to 7075 aluminum.

Among the series, the 7075-T651 aluminum alloy is particularly high-grade, and is known as the best product in the aluminum alloy, with high strength and far superior to any mild steel. This alloy also has good mechanical properties and anodic reaction. 7075 mainly contains zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, and a super-hard aluminum alloy with good wear resistance.

Uses:
7075 is often used in aviation and mold fields. For aircraft parts that require both strength and light weight, 7075 is the best choice; in the field of molds, 7075 has hardness comparable to steel, excellent thermal conductivity and better machining performance, 7075 is a good substitute for alloy steel . In addition, 7075 is also used to make golf heads. In recent years, sporting goods such as ski poles and golf bats have also been made of this alloy.
