Product Detail

    7075 Aluminum Sheet/Plate


    Alloy 7075 aluminum sheet and coil have been and remain the baseline standard with a good balance of properties required for aerospace applications.  7075 aluminum sheet is among the highest strength alloys available and used in highly stressed parts.  Corrosion resistance and machinability are rated as fair, though the addition of chromium provides good stress-corrosion cracking resistance in 7075 aluminum sheet products.  As with alloy 2024, alloy 7075 is available in bare form or in clad (“Alclad”) to offer even further protection from corrosion.


    Applications of 7075 Aluminum Sheet:

    Aircraft and aerospace structures

    Alclad skin sheet
