7000 series aluminum alloys mainly consists of alloy elements such as zinc. With few amount of magnesium alloy allows the material to undergo heat treatment so that it achieves high strength. Grade 7075 aluminium alloy has the highest strength among them and wide range of usage in aircraft frame and high-strength accessories.
Sainty provides various grades of 7000 series aluminum alloy bars and have mass storage of it. Kindly contact us for further information.
