· JVASP-151843· DyCo4B

DyCo4B is a dysprosium-cobalt boride intermetallic compound belonging to the rare-earth transition-metal boride family. This material is primarily of research and development interest rather than established high-volume production, valued for its potential in high-temperature applications and magnetic systems where rare-earth elements offer superior performance. The dysprosium-cobalt combination makes it relevant to advanced magnets, refractory systems, and specialized alloys where thermal stability and magnetic properties are critical design drivers.

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.
