· JVASP-56212· Cr2B

Cr2B is a chromium boride ceramic compound that belongs to the family of transition metal borides, characterized by high hardness and thermal stability. It is primarily investigated for wear-resistant coatings, cutting tools, and high-temperature applications where conventional materials fall short, particularly in aerospace and industrial manufacturing environments where it can extend tool life and reduce replacement costs compared to traditional cemented carbides.

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.
