Co4 B4 W4
metal· Co4 B4 W4
Co₄B₄W₄ is a cobalt-based hard metal composite combining cobalt, boron, and tungsten phases, likely developed for wear and corrosion resistance applications. This material falls within the family of cobalt superalloys and hard-facing alloys; the boron and tungsten additions promote formation of hard intermetallic compounds and carbide/boride phases that enhance surface durability. Research-stage materials of this composition are typically explored for high-temperature wear protection, erosion resistance, and environments demanding superior hardness without sacrificing some toughness—positioning it as a candidate alternative to tungsten carbides or conventional cobalt-chromium alloys in demanding industrial settings.

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.
