· JVASP-101133· NdFeCoSi2

NdFeCoSi2 is a rare-earth intermetallic compound combining neodymium, iron, cobalt, and silicon—part of the Heusler alloy family known for magnetic and structural properties. This material is primarily of research and developmental interest for high-performance magnetic applications and advanced functional devices where the synergistic combination of rare-earth elements and transition metals offers potential advantages over conventional permanent magnets or soft magnetic materials. Its use in commercial applications remains limited, with exploration focused on next-generation permanent magnets, magnetostrictive actuators, and high-temperature magnetic systems.

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.
