· Nd11Co89

Nd₁₁Co₈₉ is a rare-earth transition metal intermetallic compound combining neodymium and cobalt in a fixed stoichiometric ratio. This material belongs to the family of hard magnetic intermetallics and is primarily of research and specialized industrial interest, particularly in permanent magnet applications where rare-earth elements provide strong magnetic coupling. The neodymium-cobalt system has been explored historically as an alternative to other rare-earth permanent magnets, though modern Nd₂Fe₁₄B magnets have become more dominant in commercial applications; Nd₁₁Co₈₉ remains relevant in niche applications requiring specific magnetic properties, high-temperature stability, or corrosion resistance that cobalt-based compounds can provide.

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.
