· Cr5B3

Cr5B3 is a chromium-boron intermetallic compound belonging to the family of hard, refractory borides. This material is primarily of research and specialized industrial interest, valued for its high hardness and thermal stability in applications requiring extreme wear and thermal resistance. The chromium-boron system offers potential as a wear coating, cutting tool additive, or high-temperature structural component, though it remains less commercially mature than competing ceramics and cermets.

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.
