· VRh

VRh is a vanadium-rhodium alloy combining the refractory strength of vanadium with the corrosion resistance and high-temperature stability of rhodium. This material family is primarily explored in research and specialized aerospace contexts where extreme temperature stability, oxidation resistance, and structural integrity are simultaneously required—notably in advanced jet engine components, nuclear reactor applications, and high-performance catalytic systems where conventional superalloys reach their performance limits.

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.
