Title: COPPER ALLOY PARTICLES, SURFACE-COATED COPPER-BASED PARTICLES AND MIXED PARTICLES
Abstract:
The purpose of the present invention is to provide copper alloy particles and the like, wherein, by sufficiently melting the irradiation region with heat generated through the irradiation of a laser beam during molding in particular, a laminated molded product can be obtained which exhibits a low porosity (void fraction), and moreover has superior corrosion resistance and fatigue characteristics. These copper alloy particles 1 are used as a laminated molded material obtained by irradiation with a laser beam having a wavelength of 1.2 μm or less, and has an average particle diameter of 50 μm or less, wherein the light absorption rate of the material is 6% or more.
