· JVASP-14844· Nd

Neodymium (Nd) is a rare-earth metal belonging to the lanthanide series, characterized by its silvery appearance and high reactivity in air. It is primarily used as a critical constituent in permanent magnet alloys (notably Nd-Fe-B magnets), where it enables exceptional magnetic performance, and in specialized optical, catalytic, and metallurgical applications where its unique electronic properties are leveraged. Engineers select neodymium-based materials when high magnetic strength, thermal stability, or specialized chemical reactivity is required in compact, high-performance designs.

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.
