· JVASP-102189· NdFeNi4

NdFeNi₄ is an intermetallic compound combining neodymium, iron, and nickel, belonging to the rare-earth transition metal alloy family. This material is primarily of research and specialized industrial interest for permanent magnet applications and high-strength structural components where rare-earth strengthening is valuable. The addition of nickel to NdFe-based systems modifies magnetic properties and corrosion resistance compared to conventional NdFeB magnets, making it relevant for applications requiring enhanced thermal stability or specific magnetic performance in demanding environments.

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.
