NdCo5
metal· NdCo5
NdCo5 is an intermetallic compound in the rare-earth cobalt family, combining neodymium with cobalt in a 1:5 stoichiometric ratio. This material is primarily valued for its permanent magnetic properties and has been extensively studied as a precursor compound in the development of high-performance rare-earth magnets, particularly in the Nd2Fe14B magnet system. Engineers select NdCo5 and related rare-earth cobalt phases for applications requiring strong magnetic coupling at elevated temperatures, though modern applications have largely transitioned to iron-based rare-earth compounds offering superior energy density and cost-effectiveness.

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.
