MoRh
metal· MoRh
MoRh is a molybdenum-rhodium binary alloy that combines the high-temperature strength and refractory properties of molybdenum with the corrosion resistance and ductility of rhodium. This material is primarily of research and specialized industrial interest, used in extreme environments where both thermal stability and chemical resistance are critical, such as high-temperature catalytic applications, aerospace propulsion components, and specialized laboratory equipment. Engineers consider MoRh alloys when standard refractory metals prove inadequate for oxidizing conditions or when enhanced toughness at elevated temperatures is needed without sacrificing strength.

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.
