· MoC

Molybdenum Carbide (MoC) is a ceramic-metallic compound combining molybdenum with carbon, forming a refractory material with metallic conductivity and ceramic hardness. It is used primarily in extreme-temperature applications, wear-resistant coatings, and catalytic systems where conventional metals fail due to oxidation or thermal degradation. Engineers select MoC for environments requiring simultaneous hardness, chemical resistance, and thermal stability—particularly in chemical processing, aerospace propulsion systems, and tool applications where cost-effectiveness relative to tungsten-based alternatives is important.

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.
