Latest Patents

Nishizawa's latest patents include innovations in lamination shaping copper powder. One of his inventions involves a copper powder to which tin (Sn) is added. This innovation allows for the creation of a high-density laminated and shaped product using a fiber laser as a heat source. By appropriately reducing the electrical conductivity of copper, this method results in a product that maintains both high density and high electrical conductivity. The copper powder is designed to contain 0.5 wt % or more of the tin element, with an optimal range of 5.0 wt % or more. Additionally, when the product achieves sufficient electrical conductivity, the copper powder should contain 6.0 wt % or less of the tin element.

Another significant patent involves a copper powder with added phosphorus (P). This invention also aims to produce a high-density laminated and shaped product using a fiber laser. The copper powder is formulated to contain 0.01 wt % or more of the phosphorus element, with a desirable range of 0.04 wt % or more. The maximum recommended phosphorus content is 0.30 wt %, ensuring that no other elements are added to the copper powder.
