Abstract

The present invention provides a copper alloy for a sliding member which contains tin, sulfur, iron and phosphorus as its main components, but in which even if no iron is contained or the iron content is reduced, sliding properties are obtained which are equal or superior to the sliding properties of a conventional copper alloy. The present invention also provides a production method for producing a sliding member by casting the copper alloy. The copper alloy of the present invention consists of not less than 3.0% by mass and not more than 16.0% by mass of tin; not less than 0.3% by mass and not more than 1.0% by mass of sulfur; less than 0.3% by mass of iron; not less than 0.04% by mass and not more than 0.5% by mass of phosphorus; and a balance consisting of copper and unavoidable impurities.
