· CuSnRh2

CuSnRh2 is a copper-tin-rhodium ternary alloy combining the corrosion resistance and electrical conductivity of copper-based systems with rhodium addition for enhanced hardness and wear resistance. This material family is primarily explored in advanced bearing and sliding contact applications, electrical contact assemblies, and specialized wear-resistant coatings where traditional bronze or brass alloys fall short in demanding environments. The rhodium addition distinguishes it from conventional copper-tin bronzes, making it relevant for applications requiring both mechanical durability and thermal/electrical performance in moderate-temperature industrial settings.

Regulatory Screening

Environmental

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.
