ceramic

· YC2

YC2 is a dense ceramic compound belonging to the yttrium carbide family, characterized by high hardness and thermal stability. This material is primarily used in cutting tools, wear-resistant coatings, and high-temperature structural applications where conventional ceramics face thermal or mechanical degradation. Engineers select YC2-based ceramics over alumina or zirconia alternatives when extreme hardness combined with thermal shock resistance is required, particularly in machining operations and harsh industrial 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.
