  • Patent number: 11752556
    Abstract: This invention provides a copper powder to which tin (Sn) is added such that a high-density laminated and shaped product can be obtained by a laminating and shaping method using a fiber laser as a heat source by appropriately reducing the electrical conductivity of copper, so a laminated and shaped product having a high density and a high electrical conductivity can be obtained. That is, this invention provides a copper powder for lamination shaping in which a tin element is added to pure copper. Desirably, the copper powder contains 0.5 wt % or more of the tin element. More desirably, the copper powder contains 5.0 wt % or more of the tin element. When the product has an electrical conductivity sufficient as a copper product, the copper powder desirably contains 6.0 wt % or less of the tin element. Furthermore, no element other than the tin element is desirably added to the copper powder.
