摘要： PURPOSE:To provide a Zn-Ni alloy-electroplated Al sheet or an Al alloy sheet good in workability (powdering resistance) and moldability and having high corrosion resistance after coating as well and to provide the manufacturing method therefor. CONSTITUTION:This Al sheet or an Al alloy sheet has a Zn-Ni alloy electroplated film (Ni content: 5 to 25wt.%) incorporated with 0.01 to 20.0wt.% oxide of titanium. For manufacturing the Al sheet or Al alloy sheet, as a plating bath, a suefuric acidic Zn-Ni alloy electroplating bath contg. soluble titanium salt such as titanium chloride and titanium sulfate is used. Since this Zn-Ni alloy electropalted Al sheet or Al alloy sheet is good in powdering resistance and moldability, furthermore remarkably increased in the coating weight compared to that in the conventional one and has excellent corrosion resistance after coating, it is suitable as the Al sheet for an automotive outer sheet used in a severe corrosive environment and is easily manufactured.
