Nd2Fe14B
metal· Nd2Fe14B
Nd₂Fe₁₄B (neodymium iron boron) is a rare-earth intermetallic compound and the primary phase in sintered NdFeB permanent magnets, among the strongest magnetic materials commercially available. It is the dominant material in high-performance permanent magnets used across automotive, industrial, renewable energy, and consumer electronics applications where compact, powerful magnetic fields are essential. Engineers select NdFeB magnets over ferrite or alnico alternatives when space and weight constraints demand maximum energy density, though cost and thermal stability considerations often drive material selection trade-offs.

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.
