Aluminium 7075
Materials Aluminium 7075 T6 (AA7075)
Description
7075 T6 is a high-strength, heat-treated aluminium alloy known for its exceptional strength-to-weight ratio and fatigue resistance. Common in aerospace and motorsport applications, it performs well under high stress but offers lower corrosion resistance than other aluminium alloys. 7075 T6 is ideal where maximum performance and minimal weight are critical.
