CoB
metal· CoB
Cobalt–boron (CoB) is an intermetallic compound combining cobalt and boron, typically used as a hard ceramic or wear-resistant coating material. It finds application in cutting tools, wear-protection coatings, and catalytic systems where its hardness and thermal stability are valued. CoB is also of interest in research contexts for hydrogen storage and electrochemical applications, making it relevant for engineers working on advanced surface engineering or emerging energy technologies.

Regulatory Screening
Environmental
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.
