Copper alloy powder, method of producing additively-manufactured article, and additively-manufactured article

A copper alloy powder is a copper alloy powder for additive manufacturing. The copper alloy powder contains more than 1.00 mass % and not more than 2.80 mass % of chromium, and a balance of copper. A method for producing an additively-manufactured article includes a first step of preparing a copper...

Zusammenfassung:	A copper alloy powder is a copper alloy powder for additive manufacturing. The copper alloy powder contains more than 1.00 mass % and not more than 2.80 mass % of chromium, and a balance of copper. A method for producing an additively-manufactured article includes a first step of preparing a copper alloy powder containing more than 1.00 mass % and not more than 2.80 mass % of chromium and a balance of copper and a second step of producing the additively-manufactured article from the copper alloy powder, and the additively-manufactured article is produced such that forming a powder layer including the copper alloy powder, and solidifying the copper alloy powder at a predetermined position in the powder layer to form a shaped layer are sequentially repeated to stack such shaped layers to thus produce the additively-manufactured article.
