· JVASP-36142· CoW

CoW is a cobalt-tungsten alloy, a dense refractory metal combination that combines cobalt's magnetic and thermal properties with tungsten's high melting point and hardness. This material is used in specialized high-temperature and wear-resistant applications where extreme conditions demand both strength and thermal stability, particularly in aerospace, tooling, and industrial heating contexts where conventional steel cannot perform.

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.
