The hardness of 7075 t6 aluminium alloy is 150HB, which belongs to high hardness aluminum alloy 7000 series. The detailed specification of 7075 t6 aluminum is aluminum sheet thickness: 0.2mm-10 mm, width 400-2000mm, aluminum plate thickness 10 mm-450mm, width 400- 2400mm. 7075 t6 aluminum alloy is one of the most commercially available and precision processed aluminum plates. The main alloy element of 7075 aluminum alloy is zinc, which has strong strength, good mechanical properties and anode reaction.
After solution treatment, 7075-T6 aluminium alloy has good plasticity and heat treatment strengthening effect. It has high strength below 150℃, especially good low temperature strength, poor welding performance and stress corrosion cracking tendency. Double aging can improve SCC resistance. 7075 aluminum is one of the most powerful commercial alloys with general corrosion resistance, good mechanical properties and anode reaction. And 7075 aluminum plate is the most common used aluminum product in 7000 series. 7075 t6 aluminum alloy is mainly used to manufacture aircraft structures and other high stress structural parts with high strength and corrosion resistance, such as high-strength mechanical parts, upper and lower wing panels, purlins, etc.
7075 t6 aluminium plate is stress relieved and will not be deformed or warped after processing. It is also widely used in military industry, mold processing, mechanical equipment, tooling and fixture, etc. 7075t6 has poor welding performance and tends to stress corrosion cracking.
