Metal Powder, Method Of Producing Additively-manufactured Article, And Additively-manufactured Article

The present invention relates to a metal powder, a method of producing the additively-manufactured article, and the additively-manufactured article. The metal powder contains not less than 0.10 mass % and not more than 1.00 mass % of at least one of chromium and silicon, and a balance of copper. The total content of the chromium and the silicon is not more than 1.00 mass %. In accordance with an additive manufacturing method for this metal powder, an additively-manufactured article made from a copper alloy is provided. The additively-manufactured article has both an adequate mechanical strength and an adequate electrical conductivity. 本发明涉及金属粉末、层叠造型物的制造方法以及层叠造型物。金属粉末含有铬和硅中的至少任者0.10质量％以上且1.00质量％以下，该铬和该硅的总量为1.00质量％以下，余量为铜。通过以该金属粉末作为对象的层叠造型法，提供由铜合金构成的层叠造型物。该层叠造型物能够兼顾机械强度和导电率。
