· JVASP-127821· CuMo

CuMo is a copper-molybdenum composite or alloy that combines the excellent electrical and thermal conductivity of copper with the high-temperature strength and refractory properties of molybdenum. This material is used in specialized high-heat and high-current applications where copper alone would soften or degrade, and where molybdenum's extreme melting point provides critical performance margins. Engineers select CuMo when thermal management and electrical performance must coexist under severe operating conditions that exceed pure copper's capability.

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.
