Application for 7075 aluminum alloy
Jan 15, 2020

High-strength aluminum alloy is one of the main structural materials for the aviation industry. The development of modern aviation industry requires higher strength, better fracture toughness, and stress corrosion cracking resistance of aviation structural materials. 7075 is mainly used to manufacture aircraft structures and other high-stress structural parts that require high strength and corrosion resistance, such as aircraft upper and lower wing wall panels, beams, etc. It is also widely used in mold processing, mechanical equipment, tooling fixtures, aerospace industry, blow molding (bottle) mold, ultrasonic plastic welding mold, golf head, shoe mold, paper plastic mold, foaming mold, dewaxing mold and machinery equipment.

 7075 mainly contains zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy and a heat-treatable alloy. 7075 aluminum plate has high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is that 7075 is a high hardness and high strength aluminum alloy, which is often used in the manufacture of aircraft structures. It requires high-stress structural parts and molds with high strength and strong corrosion resistance. After solution treatment, the plasticity is good, the heat treatment strengthening effect is good, it enjoys good strength below 150 degrees, and has particularly good low temperature strength, poor welding performance, and stress corrosion cracking tendency.

7075 aluminum alloy is a kind of cold-treated wrought alloy with high strength, far superior to soft steel. 7075 is one of the strongest alloys for commercial use and high strength characteristics can be achieved through heat treatment. 7075 materials are generally added with a small amount of copper, chromium and other alloys. Among them, 7075-T651 aluminum alloy is particularly superior. It is known as the best product among aluminum alloys whcih has high strength and far exceeds any mild steel.
