Copper alloy-based slide material, and copper alloy-based slide member

摘要

Disclosed is a copper alloy-based slide material which does not contain lead and has improved anti-seizing property and improved surface pressure resistance. Also disclosed is a copper alloy-based slide member. The copper alloy-based slide material comprises: a Cu-containing parent phase (23) which contains 5 to 15 wt% of Sn; and an alloy steel particle (25) which contains a fine carbide (24) and is dispersed in the parent phase (23) at a ratio of 1 to 20 wt% relative to the total weight of the slide material. The slide material has a Vickers hardness (Hv) ranging from 44 to 148 as a macro-hardness.
