· Co12 B4

Co12B4 is a cobalt-boron intermetallic compound belonging to the hard ceramic and refractory materials family. This material is primarily of research and development interest for applications requiring high hardness, wear resistance, and thermal stability, with potential use in cutting tools, wear-resistant coatings, and high-temperature structural applications where traditional cobalt alloys or borides reach their limits. Its stiffness and hardness characteristics make it a candidate for specialized aerospace and machining applications, though it remains less established in high-volume production compared to conventional cemented carbides or boride ceramics.

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.
