· JVASP-107351· CrB2W

CrB2W is a refractory metal boride composite combining chromium diboride with tungsten, belonging to the ultra-hard ceramic-metallic material family. This material is primarily explored in research and specialized industrial contexts where extreme hardness, high-temperature strength, and wear resistance are critical; typical applications include cutting tools, wear-resistant coatings, and high-performance abrasive components where traditional cemented carbides or ceramics fall short. Its tungsten addition enhances toughness and thermal stability compared to monolithic CrB2, making it a candidate for demanding aerospace and tooling applications, though industrial adoption remains limited compared to established alternatives like WC-Co or Al2O3-based ceramics.

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.
