Aluminium Alloy   |   BS-L

L95 T651 Plate

Commercial7075 - OBSOLETE

Applications:
Aircraft and military highly stressed structural components. Rolling stock for machine parts and tools (for rubber and plastics). Screws and bolts, nuts. Rivets. Nuclear applications.

Characteristic Properties:
Heat treatable very high strength alloy with a strength slightly lower than 7010. Very high fatigue strength. Joining preferably by rivets, adhesives or screws. Corrosion protection is recommended also in outdoor atmosphere.

Precautions and Warnings:
Care to be taken when selecting temper (and other thermal treatment) for balance of properties. May be clad with 7072 for better protection against stress corrosion cracking.
