· JVASP-126920· PtAu3

PtAu3 is a platinum-gold alloy containing three parts gold to one part platinum, belonging to the noble metal alloy family. This material is valued in specialized applications requiring exceptional corrosion resistance, biocompatibility, and electrical conductivity, particularly where the lower cost of gold must be balanced against platinum's superior durability. The alloy is used primarily in high-reliability electronics, dental and medical devices, and precision jewelry where both aesthetic and functional performance are critical.

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.
