Product Description

7075 Aluminum Plate

7075 aluminum plate

Alloy 7075 aluminum plate are the outstanding member of the 7xxx series and remains the baseline among the highest strength alloys available. Zinc is the primary alloying element giving it strength comparable to steel. Temper T651 possesses good fatigue strength, fair machinability, resistance welding and corrosion resistance ratings. Alloy 7075 aluminum plate in temper T7x51 has superior stress corrosion resistance and replaces the 2xxx alloy in the most critical applications. It is widely used by the aircraft industry with the typical specifications of ASTM B209, AMS-QQ-A-250/4, as well as many end users requirements.
