7050
The main alloying element of 7050 series aluminum alloy is zinc. Adding magnesium to an alloy containing 3%-75% zinc can form a significant strengthening effect. The MgZn2 attached makes the heat treatment effect of this alloy far better than that of aluminum-zinc binary alloy. 7050 is a high-strength heat-treatable alloy.Aviation super-hard aluminum alloy has high strength and good wear resistance. Extremely high strength and resistant to spalling corrosion and stress corrosion fracture cracking performance. Commonly used in aircraft structural parts for medium and thick plate extrusions, free forgings and die forgings.
