· JVASP-116554· NdCo9Si2

NdCo9Si2 is a rare-earth transition metal intermetallic compound combining neodymium with cobalt and silicon, belonging to the family of hard magnetic and high-strength materials. This material is primarily of research and development interest for permanent magnet applications and high-temperature structural alloys, where the neodymium-cobalt combination offers potential for enhanced magnetic properties or wear resistance compared to conventional cobalt-based superalloys. The silicon addition typically improves hardness and oxidation resistance, making it relevant for aerospace and automotive applications requiring extreme performance at elevated temperatures, though industrial adoption remains limited.

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.
