White gold powder PM-AU131P

Powmet 750‰ (18 KT) WHITE GOLD (Ni-free) powder, -30+10µm

PM-AU131P is a gas atomized white gold alloy powder at title 750‰ (18 Kt), specifically developed for laser melting applications. PM-AU131P is carefully prepared by using high purity gold (99.99%) and through a special atomizing process, that guarantees spherical powder particle geometry and maximizing the powder quality. Composition and size distribution (-30+10μm) have been designed to maximize energetic absorption from laser beam during the laser melting process. PM-AU131P can be used with success in all the laser melting machines. The powder offers excellent flowability; the as cast items produced are clean from oxide scales. It has extremely high shininess and lustrous color after finishing.
