· JVASP-127524· MoW

MoW is a molybdenum-tungsten alloy that combines two refractory metals to achieve enhanced high-temperature strength and hardness. This material is valued in aerospace, tooling, and nuclear applications where extreme temperature resistance and wear resistance are critical, offering superior performance to single-element refractory metals or conventional steel alloys in demanding thermal environments.

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.
