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. When welding Aluminium 5083 to itself or another alloy from the same sub-group, the recommended filler metal is 5183. Other suitable fillers are 5356 and 5556.

The most common tempers for Aluminium 5083 are:

• 0 – Annealed wrought alloy
• H111 – Some work hardening imparted by shaping processes but less than required for a H11 temper.
• H32 – Work hardened and stabilised with a quarter hard temper.

Aluminium 5083 is used in:

• Shipbuilding: Commonly used in 5083 H116 / H321 / H112 status,  with the Classification Society certification including CCS, DNV.GL, ABS, BV, LR;
• Vehicle: Aluminum alloy tanker car body / tank, automobile fuel tank, gas tank, bus skin, C82 coal truck, automobile top / bottom guard, etc.
• Medium and Heavy Plate: Mold, LNG storage tank, flange material, GIS high-voltage switch housing, precision machining etc.
