Aluminium 7075 General Properties

Aluminium 7075 is a high-strength, heat-treatable 7XXX series alloy containing a high proportion of zinc together with magnesium and copper. It offers one of the highest strength levels among the common aluminium wrought alloys. The T6/T651 tempers target maximum strength, while the T73/T7351 tempers target improved stress corrosion resistance. It is used in aircraft fuselage and wing fittings, motorsport parts, climbing equipment, bicycle components and precision mould plates.

Characteristic Properties

Exceptional Strength-to-Weight

It gives aerospace and racing applications a very high load capacity at low mass.

Precision Machining

It machines cleanly in complex pockets, thin walls and close-tolerance mating faces.

Temper-Driven Performance

T6/T651 gives maximum strength, while T73/T7351 gives stronger stress corrosion resistance in critical environments.

Heavily Loaded Applications

It inspires confidence in fasteners, sports equipment and mould parts where repeated loading and fatigue are decisive.
