Copper alloy powder for additive manufacturing, copper alloy additively manufactured product, and manufacturing method of copper alloy additively manufactured product

Abstract

According to the present invention, it is possible to manufacture a high-strength copper alloy additively manufactured product by efficiently generating a Corson alloy containing nickel and silicon. A copper alloy powder for additive manufacturing used to manufacture an additively manufactured product by an additive manufacturing method contains nickel and silicon, a balance is formed from copper and an unavoidable impurity, and a value obtained by dividing the content (wt %) of nickel by the content (wt %) of silicon is not less than 3.3 and not more than 7.2. In a copper alloy additively manufactured product additively manufactured by an additive manufacturing apparatus, a value obtained by dividing the content (wt %) of nickel by the content (wt %) of silicon is not less than 3.3 and not more than 7.2, the copper alloy additively manufactured product contains not less than 1.5 wt % to not more than 6.0 wt % of nickel, not less than 0.35 wt % to not more than 1.5 wt % of silicon, and a balance is formed from copper and an unavoidable impurity.
