Aluminum 7075

7075 ALUMINUM SHEET


This is one of the highest strength aluminum alloys available. Its strength-to-weight ratio is excellent, and it is ideally used for highly stressed parts.

It may be formed in the annealed condition and subsequently heat treated. Spot or flash welding can be used, although arc and gas welding are not recommended.

It is available in the clad (“Alclad”) form to improve the corrosion resistance with the over-all high strength being only moderately affected.
Specifications:  Bare Sheet – QQ-A-250/12, AMS-4044 (O), AMS-4045 (T6). Alclad Sheet – QQ-A-250/13, AMS-4048 (O), AMS-4049 (T6)

Applications:   Used where highest strength is needed.

Machinability:   For automatic screw machine operations, 7075 is rated between 75% and 85% of 2011 in the T6 conditions, and 65% in the O condition.
