BeMoW
metal· JVASP-65058· BeMoW
BeMoW is a beryllium-molybdenum-tungsten ternary metal alloy combining the lightweight and thermal properties of beryllium with the high-temperature strength and refractory characteristics of molybdenum and tungsten. This material is primarily of research and specialized industrial interest, valued in applications requiring exceptional strength-to-weight ratios at elevated temperatures, though its use is limited by beryllium's toxicity concerns and the material's overall scarcity and cost. Engineers would consider BeMoW for extreme performance applications where conventional superalloys fall short on weight or where molybdenum-tungsten alloys alone lack sufficient low-temperature ductility.

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.
