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.
