6005 aluminium alloy

6005 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is closely related, but not identical, to 6005A aluminium alloy. The main difference between the two alloys is that 6005 has a higher minimum composition percentage of aluminium than 6005A (while having essentially the same maximum). The most common forming method is extrusion. It can also be forged or rolled, but as a wrought alloy it is not used in casting. It is commonly heat treated to produce tempers with a higher strength at the expense of ductility.[1]

Alternate names and designations include AlSiMg and A96005. The alloy and its various tempers are covered by the following standards:[2]

  • ASTM B 221: Standard Specification for Aluminium and Aluminium-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 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
