PtRh3
metal· JVASP-39455· PtRh3
PtRh3 is a platinum-rhodium alloy containing 25% rhodium and 75% platinum, belonging to the platinum group metal family valued for exceptional corrosion resistance and high-temperature stability. This material is used primarily in high-reliability industrial and scientific applications where chemical inertness and thermal performance are critical, particularly in thermocouple elements, laboratory crucibles, and specialized catalytic systems. Engineers select PtRh alloys over pure platinum when enhanced hardness and creep resistance are needed without sacrificing the corrosion immunity that makes platinum group metals indispensable in harsh chemical environments.

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.
