摘要:
A continuous cast aluminum alloy strip is used in the production of thin gauge or converter foils. The alloy strip contains 0.4 to 0.8% by weigth Fe and 0.2 to 0.4% by weight Si, has an an cast thickness of less than about 30 mm and contains a substantially single intermetallic species of alpha-phase. The strip is cast using a continuous strip caster, e.g. a block or belt caster.
