Factory-Direct Anti-Corrosion Aluminum Foil Aluminum Coil Aluminum Strip with Coating

7075 mainly contains zinc. It also belongs to the aviation series. It is an aluminum magnesium zinc copper alloy, a heat-treatable alloy, a super-hard aluminum alloy, and has good wear resistance. The 7075 aluminum plate is stress-relieved, and will not deform and warp after processing. All the super-large and super-thick 7075 aluminum plates are subject to ultrasonic detection, which can ensure that there are no sand holes and impurities. 7075 is an aluminum alloy with high hardness and strength, which is often used to manufacture aircraft structures and futures. It requires the manufacture of high stress structural parts and moulds with high strength and strong corrosion resistance. Basically relying on imports, China's production technology needs to be improved.

Silicon is corrosive to cemented carbide. Although aluminum alloy with more than 12% Si is generally referred to as high silicon aluminum alloy, diamond tools are recommended, but this is not absolute, and the destructive force of the tool is gradually increased with the increasing silicon content. Therefore, some manufacturers recommend diamond cutters when the silicon content exceeds 8%.
