Prodsuct Introdsuction
Aluminium 5083 is a medium-strength magnesium-manganese-chromium-aluminium alloy. The 5000 series grades of aluminium are non-heat-treatable alloys. Aluminium 5083 is known for its exceptional performance in extreme environments. Aluminium 5083 is highly resistant to attack by both seawater and industrial chemical environments. The temper is achieved by the sheet being fully annealed and then rolled to the required temper, rather than being heat treated. It has the highest strength of the non-heat-treatable alloys but is not recommended for use in temperatures in excess of 65°C.
