· JVASP-101732· CrB4Mo

CrB4Mo is a chromium-molybdenum boride compound, part of the transition metal boride family known for exceptional hardness and wear resistance. While primarily of research and developmental interest rather than widespread commercial use, this material represents exploration into ultra-hard ceramic-metal composites with potential for cutting tools, wear surfaces, and high-performance bearing applications where conventional tool steels and carbides reach their limits.

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.
