In conjunction with ISO 6361-1, this part of ISO 6361 specifies the mechanical properties of wrought aluminium and aluminium alloy sheets, strips, and plates for general engineering applications. It applies to flat-rolled products. The chemical composition of these materials is given in ISO 6361-5. The designations of aluminium and aluminium alloys and the temper designations used in this part of ISO 6361 are in accordance with ISO 2107. NOTE In certain countries, for purposes of mechanical properties, the thickness limit can be lowered to 0,15 mm by agreement between the purchaser and the supplier, in the case of sheets and strips.
