Welding 5083 Aluminum. Aluminium 5083 is highly resistant to attack by both seawater and industrial chemical environments. 5083- 5 Mg is the highest strength non-heat-treatable alloy in commercial use.
Machining Machinability of 5083 is poor due to its high strength. 5083 provides good formability and weldability. When welding aluminum the designer must not assume that the properties of the starting material and the properties of the weld are equivalent.
It has the highest strength of the non-heat treatable alloys but is not recommended for use in.
The 5556 base alloy has slightly higher mechanical properties over the 5183 and can be used to weld the slightly higher strength 5456 base material but will also meet the minimum tensile requirements for the 5083 base material. The 5556 base alloy with slightly higher mechanical properties than the 5183 will meet the minimum requirements for the 5083 base alloy. Aluminium 5083 is highly resistant to attack by both seawater and industrial chemical environments. When welding aluminum the designer must not assume that the properties of the starting material and the properties of the weld are equivalent.
