· Y2C

Y2C is a rare-earth carbide ceramic composed of yttrium and carbon, belonging to the family of refractory carbides used in extreme-temperature and wear-resistant applications. This material is valued in specialized industrial sectors where conventional ceramics or metals cannot tolerate high thermal stress, chemical aggression, or severe mechanical wear. Y2C is notable for its combination of hardness and thermal stability, making it relevant for cutting tool coatings, high-temperature structural components, and wear-resistant surfaces in demanding environments.

Regulatory Screening

Environmental

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.
