Co4B
metal· JVASP-144680· Co4B
Co₄B is a cobalt-boron intermetallic compound that belongs to the family of transition metal borides, which are known for high hardness and thermal stability. This material is primarily of research and development interest rather than established industrial production, with potential applications in hard coatings, wear-resistant surfaces, and high-temperature structural applications where cobalt's strength and boron's hardening effects are leveraged together.

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.
