PlatinII

PlatinII is a line of platinum-based alloys and protective coatings developed for high-performance applications in jewelry, medical devices, and industrial components. The designation II indicates the second generation of the alloy family, marketed by PlatinTech Industries since the early 2010s.

Composition and properties: PlatinII alloys are primarily platinum with minor alloying additions, typically ruthenium, palladium, and iridium, in approximate ranges Pt 85–95%, Ru 3–10%, Pd 0–5%, Ir 0–2%. The additions improve hardness, wear resistance, and oxidation resistance without significantly compromising the metal’s biocompatibility and corrosion resistance. The alloys retain a high melting point and are generally inert to common chemical environments.

Manufacturing and finishing: produced by vacuum arc remelting and subsequent thermo-mechanical processing. Finishes include mechanical polishing, electrochemical polishing, and protective coatings to enhance surface durability. The II generation includes refinements to grain structure to improve machinability and thermal stability.

Applications: used in luxury jewelry and timepieces for enduring wear and colorfastness; medical devices such as implants and surgical tools where biocompatibility is essential; and certain industrial components, including chemical processing equipment and high-performance connectors.

History and market: PlatinII was introduced as a second-generation evolution of early platinum alloys intended to combine the prestige of platinum with improved mechanical performance. It competes with other platinum-group metal alloys and is subject to market fluctuations in platinum prices. The term PlatinII may also appear in patents and product documentation to denote second-generation formulations.
