Excellent Performance of 7075 Aluminum Profiles
Excellent Performance of 7075 aluminum profiles
7075 tensile strength can reach 524Mpa, yield strength can reach 455Mpa, mainly used in aerospace, mold processing, mechanical equipment, fixtures, especially for the manufacture of aircraft structures and other high stress and high corrosion resistance Structure.
7075 aluminum profile is a cold-treated forging alloy with high strength and far better than mild steel. 7075 is one of the most powerful alloys in the industry, with common corrosion resistance, good mechanical properties and anodic reaction. The fine grain makes the deep drilling performance better, the tool wear resistance is enhanced, and the thread rolling is more distinctive. Zinc is the main alloying element in 7075. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with remarkable strengthening effect, which makes the heat treatment effect of the alloy far better than the aluminum-zinc binary alloy. Increasing the zinc and magnesium content in the alloy will further increase the tensile strength, but its ability to resist stress corrosion and flaking corrosion will decrease. Subject to heat treatment, very high strength properties can be achieved. 7075 materials are generally added with a small amount of copper, chromium and other alloys. Among them, 7075-T651 aluminum alloy is especially top grade. It is known as the best product in aluminum alloy, with high strength and far better than any mild steel. This alloy has good mechanical and anodic reaction.
