SmNi2
metal· JVASP-19698· SmNi2
SmNi₂ is an intermetallic compound formed between samarium (a rare-earth element) and nickel, belonging to the family of rare-earth intermetallics. This material exhibits strong magnetocrystalline anisotropy and is primarily investigated for permanent magnet and magnetostrictive applications where controlled magnetic properties are critical. SmNi₂ is largely a research-phase material used in specialized magnetic device development and competing against more established rare-earth compounds like SmCo₅ in niche high-performance applications.

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.
