Introduction

Aluminium / Aluminum alloys are known for their strong corrosion resistance. These alloys are sensitive to high temperatures ranging between 200 and 250°C (392 and 482°F), and tend to lose some of their strength. However, the strength of the aluminium / aluminum alloys can be enhanced at subzero temperatures, thus making them ideal low-temperature alloys.

The aluminium / aluminum 5252 alloy is a wrought, non-heat treatable alloy. The 5252 alloy has medium strength but retains its excellent corrosion resistance. The following datasheet will provide more details about the aluminium / aluminum 5252 alloy.

Machinability

The machinability of the aluminium / aluminum 5252 alloy is poor when compared with other aluminium / aluminum alloys. If machining is performed, lubricating oil must be used. However, the finish tends to be ‘gummy’.

Forming

The aluminium / aluminum 5252 alloy can be hot and cold formed very easily.

Welding

The aluminium / aluminum 5252 alloy is weldable using commercial welding methods. The preferred methods are TIG and /or MIG. Brazing method is not suitable.

Forging

The aluminium / aluminum 5252 alloy is forgeable from 510 to 371°C (950 to 700°F).

Hot Working

The aluminium / aluminum 5252 alloy can be hot worked if required in the range of 482°C (900°F) down to 260°C (500°F).

Cold Working

The aluminium / aluminum 5252 alloy can be easily cold worked using the conventional methods. It is suited for cold forming by blanking, drawing, or bending.

Annealing

The aluminium / aluminum 5252 alloy can be annealed at 343°C (650°F) and then air cooled.

Hardening

The aluminium / aluminum 5252 alloy can be hardened by cold working only.

Applications

The aluminium / aluminum 5252 alloy is widely used in the manufacture of automotive trim and appliances.
