Prodsuct Introdsuction
The 7XXX series aluminum alloy represents 7055 mainly containing zinc. It also belongs to the aerospace series. It is an aluminum-magnesium-zinc-copper alloy and is a heat-treatable alloy. It is a super-hard aluminum alloy with good wear resistance. It also has good weldability but poor corrosion resistance. 7075 aluminum sheet belongs to Al-Zn-Mg-Cu super-hard aluminum. The plasticity of 7075 in the annealed and as-quenched state is slightly lower than 2A12 in the same state. It is slightly better than 7A04. The static fatigue of the sheet is sensitive to notches and has excellent stress corrosion performance. In 7A04, the state of 7075-T651 is particularly top-grade, and it is known as the most excellent prodsuct among aluminum alloys with high strength and far better than mild steel. This alloy has good mechanical properties and anode reaction and is a typical aerospace aluminum alloy material.
