Properties of 7075 Aluminum Forging
Aluminum 7075 refers to a common alloy in 7-series aluminum alloy, and 7075 alloy is the most common aluminum alloy with the best strength. It is widely used in CNC cutting parts, suitable for aircraft frames and high-strength parts. The 7-series aluminum alloy contains zinc and magnesium. Zinc is the main alloying element in this series, so corrosion resistance is quite good, plus a little magnesium alloy allows the material to be heated to very high strength.
Application：Aerospace fixtures, trucks, tower structures, ships, tubes, and other applications where strength is required. Such as aircraft parts, gears and shafts, fuse parts, instrument shafts, and gears, missile parts jump valve parts, turbines, keys, aircraft, aerospace, and defense applications.
