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.
Machinability
Aluminium 6060 has fair machinability with excellent formability. The machinability properties of aluminium 6060 makes it ideal for decorative anodising.
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.
