Aluminium 6060

Scope

This data sheet applies to cold drawn and extruded rod/bar, tubes and profiles made of aluminium-silicon alloyEN AW-6060.

Application

Among the heat treatable aluminium alloys the material EN AW-6060 shows medium mechanical properties and a good atmospheric and seawater corrosion resistance. The material is good weldable and is used for example in the automotive and railway industry.The alloy EN AW-6060 is heat treatable and it is suitable for decorative anodizing.

Processing / Welding

The material is good weldable with the conventional processes (MIG and TIG). As welding filler metal is SG-AlMg5, SG-AlSi and SG-AlMg3 recommended. In annealed temper there may arise some difficulties during machining (for example ribbon or thread chips). The machinability improves with the grade of ageing.

Remarks

According to EN 602 the use of the material is allowed for the contact with food.For decorative anodizing the material EN AW-6060 should be selected as anodizing quality acc. to DIN 17611 for quality reasons.
