7075
7075 aluminum alloy is a cold-processed forged alloy with high strength, much better than mild steel. 7075 is one of the strongest alloys commercially available
one. After heat treatment, it can achieve very high strength properties. 7075 materials generally add a small amount of copper, chromium and other alloys.
Among the series, 7075-T651 aluminum alloy is particularly top-grade and is known as the best product among aluminum alloys. It has high strength and is far superior to any soft material.steel. This alloy also has good mechanical properties and anodic reaction.
