COPPER ALLOY POWDER FOR ADDITIVE MANUFACTURING, ADDITIVELY MANUFACTURED COPPER ALLOY ARTICLE, AND METHOD FOR MANUFACTURING COPPER ALLOY ADDITIVELY-MANUFACTURED ARTICLE

WIPO Patent Application WO/2023/248453

A1

The present invention makes it possible to manufacture an additively-manufactured copper alloy article having high strength by efficiently producing a Corson alloy from nickel and silicon. This copper alloy powder for additive manufacturing is used to manufacture an additively-manufactured article by additive manufacturing, the copper alloy powder for additive manufacturing containing nickel and silicon with the remainder made up by copper and unavoidable impurities, the value obtained by dividing the nickel content (wt%) by the silicon content (wt%) being 3.3 to 7.2. This copper alloy additively-manufactured article is additively manufactured by an additive manufacturing device, the copper alloy additively-manufactured article containing 1.5 wt% to 6.0 wt% of nickel and 0.35 wt% to 1.5 wt% of silicon with the remainder made up by copper and unavoidable impurities, and being such that the value obtained by dividing the nickel content (wt%) by the silicon content (wt%) is 3.3 to 7.2.
