· JVASP-100155· CoW3

CoW₃ is a cobalt-tungsten intermetallic compound representing a hard, high-density material from the refractory metal alloy family. It appears in industrial applications requiring exceptional hardness and wear resistance, particularly in cutting tools, wear parts, and high-temperature applications where conventional steels and standard tungsten carbides may be insufficient. This material is notable for its potential to combine cobalt's toughness with tungsten's extreme hardness and density, making it relevant for engineers seeking alternatives to WC-Co composites in specialized demanding environments.

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.
