Data Sheets

Aluminium Alloy - Commercial Alloy

5083 - H321 Sheet


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.

Applications
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 H321 temper
