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.
This material is used for pressure vessels, tip truck bodies, rail cars, ship building, vehicle bodies and mine skips & cages
Alloy 5083 also corresponds to: GM41, A95083, AIMg 4.5 Mn and Al Mg 4.5 Mn 0.7.
The most common tempers for 5083 aluminium are: O - Soft, H111 - Some work hardening imparted by shaping processes but less than required fro H11 temper and H32 - Work hardened by rolling then stabilised by low temperature heat treatment to quarter hard.
- Solderability: Poor
- Weldability - Gas: Average
- Weldability - Arc: Excellent
- Weldability - Resistance: Excellent
- Brazability: Poor
- Workability - Cold: Average
- Machinability: Poor
When welding 5083 to itself or another alloy from the same sub-group, the recommended filler metal is 5183. Other suitable fillers are 5356 and 5556.
