Aluminum 5083 Australian stockist

Marine plate aluminium 5083 dimensions


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

Alloy 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.

Alloy 5083 is typically used in:

  • Shipbuilding
  • Rail cars
  • Vehicle bodies
  • Tip truck bodies
  • Mine skips and cages
  • Pressure vessels

Mechanical properties shown are for 0/H111 temper.

Temper types

The most common tempers for 5083 aluminium are:

  • 0 - Soft
  • H111 - Some work hardening imparted by shaping processes but less than required for H11 temper
  • H32 - Work hardened by rolling then stabilised by low temperature heat treatment to quarter hard
