TaWC2
metal· JVASP-101689· TaWC2
TaWC2 is a tantalum-tungsten carbide composite material belonging to the refractory metal carbide family, combining the extreme hardness and wear resistance of carbide phases with the toughness contributions of tantalum. This material is used in cutting tool inserts, wear-resistant coatings, and high-temperature structural applications where conventional tool steels and tungsten carbides reach their performance limits. Engineers select TaWC2-type composites when extreme hardness, thermal stability above 1000°C, and resistance to adhesive wear are critical—particularly in machining hard superalloys, ceramics, and composites where tool life and edge retention significantly impact manufacturing economics.

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.
