· JVASP-128057· CuPt3

CuPt3 is an intermetallic compound composed of copper and platinum in a 1:3 stoichiometric ratio, forming an ordered metallic phase with a cubic crystal structure. This material exhibits exceptional hardness and high-temperature stability, making it of interest in aerospace and high-performance applications where extreme conditions demand materials resistant to thermal cycling and oxidation. CuPt3 remains primarily in the research and development phase rather than widespread industrial production, with potential advantages in specialized applications where the platinum content justifies the cost relative to conventional superalloys or refractory metals.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
