摘要
A sintered alloy article having superior corrosion resistance while also ensuring product dimensional accuracy is provided. A sintered alloy body is formed by molding and sintering (S2) a raw material powder containing copper, and tin plating (S4) treatment on this sintered alloy body is performed, followed by sizing (S5). When the tin plating layer is compressed during sizing, the tin plating layer is formed to a nearly uniform thickness, pores opened in the outer surface of the sintered alloy body are blocked by the above tin plating, as a result of said tin plating being compressed by the above sizing. Moreover, by combining a copper-based sintered alloy and tin plating, a sintered body is obtained provided with both corrosion resistance to sulfur and its compounds as well as corrosion resistance to formic acid, acetic acid and other organic acids.
