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.Marks' Standard Handbook for Mechanical Engineers, 8th Ed., McGraw Hill, pp. 6-50 to 6-52
