· CrB2

Chromium diboride (CrB₂) is a ceramic compound belonging to the transition metal boride family, combining chromium with boron in a hard, refractory phase. It is used in wear-resistant coatings, cutting tool materials, and high-temperature structural applications where extreme hardness and thermal stability are required. CrB₂ is valued as an alternative to traditional hard ceramics and cermets because of its combination of hardness and relative toughness, making it suitable for abrasive environments where conventional materials degrade rapidly.

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.
