· JVASP-108792· CrCoB

CrCoB is a chromium-cobalt-boron ternary alloy combining the corrosion resistance and strength of cobalt-chromium systems with boron's hardening and wear-resistance effects. This material family is primarily investigated for high-performance coatings and wear-resistant applications where enhanced surface hardness and tribological performance are required without sacrificing the biocompatibility or corrosion resistance inherent to CoCr base alloys. Engineers select CrCoB-type compositions when standard cobalt-chromium alloys need improved hardness, reduced friction, or extended service life in aggressive environments.

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.
