Aluminium alloy 5005 is a medium strength alloy with very good resistance to atmospheric corrosion and very good weldability that is highly suitable for decorative anodising. PLEASE NOTE THAT WHILST ALLOY 5005 IS SUITABLE FOR ANODISING, STREAKS CAN OCCUR - IF THE FINISH YOU ARE SEEKING IS CRITICAL PLEASE SPECIFY 'SPECIAL ANODISING QUALITY' AT TIME OF ORDER. This is a non-heat treatable alloy of aluminum with magnesium content. Cold working will strengthen (harden) the alloy and it is very good in both corrosion resistance and weldability.
