· Mo2C

Mo₂C is a molybdenum carbide ceramic compound that belongs to the family of refractory metal carbides, known for exceptional hardness and thermal stability at elevated temperatures. It is employed primarily in cutting tools, wear-resistant coatings, and catalytic applications where extreme conditions demand materials that can withstand both mechanical stress and thermal shock. Engineers select Mo₂C over conventional tool steels and tungsten carbide alternatives when applications require superior chemical inertness, enhanced catalytic performance in hydroprocessing, or lower material density without sacrificing hardness—making it particularly valuable in petroleum refining, metal machining, and high-temperature structural applications.

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.
