7 series of products

Features: zinc-based, but sometimes a small amount of magnesium, copper. The super hard aluminum alloy is containing zinc, lead, magnesium and copper alloy close to the hardness of steel. The extrusion speed is slower than that of 6 series alloy, and the welding performance is good. 7005 and 7075 are the highest grades in the 7 series and can be strengthened by heat treatment. Applications: Aviation (aircraft load-bearing components, landing gear), rockets, propellers, aerospace vehicles.
