A coated aluminium-base alloy comprises a core, i.e. a strip, of the alloy, a cladding of at least 99% pure aluminium on at least one face of the core, and a coating applied to the cladding. The alloy is defined as containing more than 50% by weight of aluminium and may be an aluminium-magnesium or aluminium-manganese alloy. The thickness of the cladding on one or both faces may be not more than 5% of the total metal thickness. The coating may be of lacquer, e.g. an epoxy or vinyl lacquer, of printing ink, paint, metal, e.g. by electroplating, or adhesives for attaching preformed films, or films formed in situ, e.g. of plastics. |
