6060 Aluminum Alloy Plate

 

6060 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is much more closely related to the alloy 6063 than to 6061. The main difference between 6060 and 6063 is that 6063 has a slightly higher magnesium content. It can be formed by extrusion, forging or rolling, but as a wrought alloy it is not used in casting. It cannot be work hardened, but is commonly heat treated to produce tempers with a higher strength but lower ductility.


Alternate names and designations include AlMgSi, 3.3206, and A96060. The alloy and its various tempers are covered by the following standards:[2]

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.


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.
