Abstract

PURPOSE: To enhance close adhesiveness of a tin plating layer by a method wherein Cu is chemically plated on a surface of an electroconductive Al alloy and, thereafter, Cu is further plated electrically and the Sn plating is applied thereon in an alkali bath.
CONSTITUTION: In order to reduce contact resistance of the Al alloy used in an electroconductive part, the Sn plating is applied on a surface thereof. In this case, Cu is chemically plated on the surface of the Al alloy at first and, thereafter, a Cu plating layer is again formed by electroplating in a thickness of 10μ. Finally, the Sn plating layer is formed on the Cu electroplating layer in an alkali bath such as an Na bath or a K bath by electroplating. Thereby, the Sn plating layer which is not peeled even if heated at a high temp. and is excellent in the close adhesiveness is formed.
