· JVASP-100170· Cu3Rh

Cu3Rh is an intermetallic compound combining copper and rhodium in a 3:1 ratio, belonging to the family of copper-rhodium alloys used in high-performance applications. This material is primarily of research and specialized industrial interest for applications requiring excellent corrosion resistance, high thermal stability, and catalytic properties that neither pure copper nor rhodium alone can efficiently provide. Cu3Rh appears in catalytic converters, wear-resistant electrical contacts, and advanced coating systems where the synergistic properties of both elements deliver superior performance compared to single-metal alternatives, though it remains less common than binary copper alloys due to cost and processing complexity.

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.
