Co3C
metal· JVASP-59689· Co3C
Co₃C is a cobalt carbide compound that forms as a hard, brittle phase in cobalt-based metallurgical systems. It is primarily encountered in tool materials, wear-resistant coatings, and cemented carbide composites where it either acts as a binder phase or strengthening constituent. Co₃C is valued for its high hardness and thermal stability, making it an alternative to tungsten carbide-cobalt systems in specialized cutting tool and abrasive applications, though it is less widely deployed in industry than WC-Co due to cost and processing complexity.

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.
