Abstract
The present invention relates to sliding material provided by sintering a lead-free copper or copper alloy and contains at least one mineral selected from the group consisting of talc, mica, kaolinite mineral and montmorillonite mineral. Pb has conventionally been included in sliding materials for the purpose of obtaining conformability and seizure resistance. Despite the absence of Pb, the Pb-free copper-based sliding material and sliding parts according to the present invention have improved sliding properties.
