6060 aluminium alloy
# 6060 aluminium alloy

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:

* ASTM B 221: Standard Specification for Aluminum and Aluminum-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes
* EN 573-3: Aluminium and aluminium alloys. Chemical composition and form of wrought products. Chemical composition and form of products
* EN 754-2: Aluminium and aluminium alloys. Cold drawn rod/bar and tube. Mechanical properties
* EN 755-2: Aluminium and aluminium alloys. Extruded rod/bar, tube and profiles. Mechanical properties
* ISO 6361: Wrought Aluminium and Aluminium Alloy Sheets, Strips and Plates
