Characteristics

Machinability

The machinability of Aluminium / Aluminum 5052 alloy is rated as fair. This alloy can be easily machined in hard temper than in annealed form, and the quality of finish is better. Other than in very light cuts, all other machining should be done using oil lubricants.

Forming

Aluminium / Aluminum 5052 alloy can be easily formed at room temperature. However, consecutive cold working tends to reduce the alloy’s formability

Welding

Welding can be easily performed on Aluminium / Aluminum 5052 alloy using conventional methods. In case a filler rod is needed, it should be Aluminium / Aluminum 5356 alloy as filler. The most suitable welding methods are tungsten or consumable electrode inert gas shielded arc welding.

Forging

Aluminium / Aluminum 5052 alloy can be forged from 510°C (950°F) down to 260°C (500°F).

Hot Working

Aluminium / Aluminum 5052 alloy can be hot worked easily from 510°C (950°F) down to 260°C (500°F).

Cold Working

Aluminium / Aluminum 5052 alloy is easy to cold work. It can be formed by spinning and drawing. Depending on the extent of spinning, annealing may be required intermediately.

Annealing

Aluminium / Aluminum 5052 alloy can be annealed at 343°C (650°F) and then air cooled.

Hardening

Aluminium / Aluminum 5052 alloy can be hardened by cold working only.
