· JVASP-156680· PtAu

PtAu is a platinum-gold alloy that combines the corrosion resistance and chemical inertness of platinum with gold's workability and thermal properties. This precious metal alloy is used primarily in high-reliability electronics, jewelry manufacturing, and specialized chemical processing equipment where both noble metal performance and cost optimization are important considerations. Engineers select PtAu when exceptional corrosion resistance, electrical stability, and biocompatibility are required but the expense of pure platinum can be partially offset through gold alloying.

Export Control

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.
