· JVASP-55185· NdCo4B4

NdCo4B4 is a rare-earth cobalt boride intermetallic compound that combines neodymium, cobalt, and boron in a fixed stoichiometric ratio. This material belongs to the family of rare-earth transition metal borides, which are primarily investigated for their potential hard magnetic and high-temperature structural properties. While NdCo4B4 remains largely in the research phase, compounds in this family are of interest for permanent magnet applications and wear-resistant coating systems where the combination of magnetic strength and hardness at elevated temperatures could offer advantages over conventional alloys.

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.
