7 series alloy aluminium sheet:zinc mainly, but sometimes also a small amount of magnesium, copper. Among them, super hard alloy is the hardness of the alloy containing zinc, lead, magnesium and copper alloy approaching to steel. The extrusion speed is slower than that of the 6 series alloy, and the welding performance is good. 7005 and 7075 aluminium sheet plate are the highest grade in the 7 series, which can be enhanced by heat treatment. Applications: Aviation (aircraft bearing components, landing gear), rocket, propeller, air vehicle.
