Abstract
PURPOSE:To suppress the generation of black stripe after can forming by coating a specific amt. of oil film on the surface of an Al alloy plate in which the component ratios, the size distribution of intermetallic compounds, its areal ratio, contact angle and surface coarseness are specified. CONSTITUTION:The compsn. of the titled Al alloy plate contains, by weight, 0.8-1.5% Mn, 0.8-1.5% Mg, 0.05-1.00% Zn, 0.05-0.50% Cu, 0.30-0.80% Fe and 0.10-0.60% Si. At this time, the intermetallic compounds in the alloy are specified in such a manner that the maximum size is regulated to <=20mum, those having 15-20mum size are distributed in the ratio of <=20 pieces/mm<2> and the areal ratio is regulated to 1.5-4.0%; the contact angle thereof is regulated to <=60 deg. and the surface coarseness Ra is regulated to 0.10-0.40mum. Mineral oil or synthetic oil is coated on the surface of said Al alloy plate to provide said surface with an oil film of 50-500mg/m<2>. By this method, the black stripe resistance can be improved even at the time of the lubrication conditions in case of cup forming are inferior.
