Description
The Umicore 95% Pt. / 5% Ru platinum casting alloy is among the most popular platinum among jewelry manufacturers in the U.S.
This alloyed platinum has an annealed hardness of 120 HV (Vickers hardness) and a working hardness of approximately 220 HV, along with high tensile strength.
These properties — refined grain structure, excellent hardness, and strength — make the Pt/Ru alloy well suited for machine casting and polishing, making it an ideal choice for ring manufacturing. Available in small rod form, this .950 platinum alloy produces bright, high-quality finished jewelry pieces
