· Nb4 Co4 B8

Nb₄Co₄B₈ is a complex intermetallic compound combining niobium, cobalt, and boron elements, representing a multi-principal-element alloy system that falls within the broader family of refractory metal borides and high-entropy metallic materials. This composition is primarily found in academic research contexts rather than established industrial production, where it is being investigated for potential applications requiring high-temperature strength, hardness, and wear resistance in extreme operating environments. The material's appeal lies in its potential to combine the refractory properties of niobium boride with cobalt's mechanical toughness, positioning it as a candidate alternative to conventional tool steels or ceramic composites in specialized wear and thermal applications.

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.
