In a copper-based sintering sliding material, to reduce attacking power to the counter material by expressing an ability to scrape a local adhered object on the sliding surface, improve abrasion resistance of the material, and suppress the abrasive heat generation due to the hard phase, thereby improving the seizure limit, heat shock resistant ceramics comprising two or more selected from SiO2 and/or SiO2, Al2O3, LiO2, TiO2 and MgO are dispersed in an amount of 0.05 to 0.5% by weight or less, as nonmetallic particles comprising one or more kind(s) selected from finely grinded oxides, carbides and nitrides.
A copper-based sintering sliding material wherein finely grinded nonmetallic particles comprising one or more kind(s) selected from oxides, carbides, nitrides and carbonitrides are dispersed in an amount ranging from 0.2% by volume, inclusive, to 4% by volume, exclusive.
A copper-based sintering sliding material, wherein one or more intermetallic compound(s) comprising two or more selected from Ni, Si, Ti, Co, Fe, Al, V and P is/are dispersed, and the adding amount thereof is in the range of 0.5 to 10% by weight in terms of a total adding amount of two or more selected from Ni, Si, Ti, Co, Fe, Al, V and P.
A copper-based sintering sliding material, wherein one or more intermetallic compound(s) comprising two or more selected from Cu, Sn, Ca, Mn, Cr, Mo, W, Sb and Te is/are dispersed, and the adding amount thereof is in the range of 0.1 to 10% by volume in terms of intermetallic compound.
A copper-based sintering sliding material, wherein one or more intermetallic compound(s) comprising two or more selected from Ni, Si, Ti, Co, Fe, Al, V and P is/are dispersed, and further one or more intermetallic compound(s) comprising two or more selected from Cu, Sn, Ca, Mn, Cr, Mo, W, Sb and Te is/are dispersed, and the adding amount thereof is in the range of 0.1 to 10% by volume in terms of intermetallic compound.
