This is a kind of 7000 serial aluminum-zinc-magnesium alloy.Aluminium Alloy 7075 is one of the highest strength alloys available.It is applied to make airplane structural component and other structural component with high stress requiring high strength and corrosion resistance, such as surface plate of airplane upper and lower wings, purlin and bulkhead. It has high plasticity after solution treatment, good reinforcement performance after heat treatment, high strength in the condition under 150℃, excellent low temperature strength, bad weldability, liable to crack under stress corrosion, double-aging may improve SCC performance.
