ABSTRACT:
A conventional Bi-containing sliding material sometimes underwent seizing in a sliding part operating at a high rotational speed. The present invention provides a sliding material which does not undergo seizing in a sliding part operating at a high rotational speed and a method for its manufacture. A low melting point alloy containing at least 20 mass % of Bi and having a liquidus temperature of at most 200° C. is made to penetrate into a porous portion comprising a Cu—Sn based alloy. A Bi—Sn based alloy or a Bi—In based alloy is suitable as the low melting point alloy. After a low melting point alloy paste is applied to a porous portion, the low melting point alloy is melted and made to penetrate into the porous portion.
