Representative 7075 mainly contains zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy. It is a heat-treatable alloy. It is a super-hard aluminum alloy and has good wear resistance. The 7075 aluminum plate is stress-relieved and will not deform or warp after processing. All oversized super All thick 7075 aluminum plates have been ultrasonically detected to ensure there are no blisters or impurities. The 7075 aluminum plates have high thermal conductivity, which can shorten molding time and improve work efficiency. The main feature is its high hardness.
7075 is a high-hardness, high-strength aluminum alloy that is often used in manufacturing aircraft structures and futures. It requires high-stress structural parts and mold manufacturing with high strength and strong corrosion resistance. Basically relying on imports, my country's production technology still needs to be improved. (A foreign company in this company once pointed out that domestically produced 7075 aluminum plates are unevenly annealed, resulting in inconsistent surface and internal hardness of the aluminum plates)
The more commonly used ones are 8011 which belongs to other series. In my memory, the aluminum plate is mainly used for making bottle caps. It is also used in radiators, and most of them are aluminum foil. Not commonly used.
