PtAu3
metal· 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.
