7010 aluminium alloy offers a balance between mechanical properties (strength, toughness, fatigue) and resistance to stress corrosion. The alloy which is of European origin has properties similar to the American Grade 7050. The alloy benefits from high strength, high fatigue strength and is stress corrosion resistant. 7010 is used in the aerospace industry in the production of high strength parts.
Alloy 7010 is typically used for:
