Abstract:
Provided is a sliding material including a substrate; and a copper alloy layer bonded to the substrate. The copper alloy includes 2.0 to 15.0% by mass of tin. The copper alloy layer includes a sliding body part including a sliding surface, and a gradient region including a bond surface with the substrate. A tin concentration in the gradient region reduces from the sliding body part toward the bond surface. A method for producing the siding material is also provided. The method includes preparing the substrate having a first surface and a second surface opposite to the first surface; melting the copper alloy; casting the molten copper alloy on the first surface of the substrate; and solidifying the copper alloy unidirectionally by cooling the substrate from the second surface by a coolant.

Claim (Index 5):
The sliding material according to  claim 1 , wherein the copper alloy further comprises not more than 10.0% by volume in total of either or both of MoS 2  and graphite.
