7075 alclad sheet aluminum alloy belongs to Al-Zn-Mg-Cu series super-durable aluminum. This alloy is a high-strength deformed aluminum alloy that has been widely used in the aircraft industry since the late 1940s and is still widely used in the aviation industry. It is characterized by good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150 ℃, and particularly good low temperature strength; poor welding performance; tendency to stress corrosion cracking; need to be coated with aluminum or other Protective use. Two-stage aging can improve the alloy's ability to resist stress corrosion cracking.
7XXX series aluminum alloy represents 7075 mainly contains zinc element. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy which is a heat-treatable alloy. It is a super-hard aluminum alloy and has good wear resistance. It also has good weldability but poor corrosion resistance.
7075 alclad sheet belongs to Al-Zn-Mg-Cu series super-durable aluminum. The plasticity of 7075 in the annealed and hardened state is slightly lower than that of 2A12 in the same state. It is slightly better than 7A04. The static fatigue of the sheet. Notch sensitivity, stress corrosion resistance It is superior to 7A04, among which the state of 7075-T651 is particularly superior, known as the excellent product among aluminum alloys, with high strength and far superior to mild steel. This alloy has good mechanical properties and anode reaction and is a typical aluminum alloy material for aerospace.
7075 alclad sheet main applications: aerospace fixtures, trucks, tower buildings, ships, pipelines and other applications that require strength, weldability, and corrosion resistance. Such as: aircraft parts, gears and shafts, fuse parts, instrument shafts and gears and other applications.
