Aluminium 5083 is known for exceptional performance in extreme environments. Aluminium 5083 is highly resistant to attack by both seawater and industrial chemical environments.

Aluminium 5083 also retains exceptional strength after welding. It has the highest strength of the non-heat treatable alloys but is not recommended for use in temperatures in excess of 65°C.

    I have a question about acceptance criteria of "impact toughness" for aluminium alloy welds (in particular, Al 5083). I appropriated it if you help me with this question... What is the exact reference for acceptance criteria of impact test of aluminium welds? I need detailed information. Thank you
