· B2 Co4

B2 Co4 is a cobalt-based intermetallic compound with the B2 (CsCl-type) crystal structure, classified as a semiconductor material. This ordered intermetallic represents a research-phase material being investigated for applications requiring high stiffness and thermal stability in harsh environments where conventional alloys may degrade. Intermetallic compounds like Co4-based systems are of interest for high-temperature structural and functional applications, though they remain primarily in development stages compared to established superalloys or ceramics; their brittleness and processing challenges typically limit industrial adoption but their combination of ordered atomic structure and metallic bonding offers potential for aerospace, turbine, or extreme-environment applications where weight and temperature resistance are critical.

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.
