· JVASP-133283· Sm2Co17H3

Sm₂Co₁₇H₃ is a samarium-cobalt based permanent magnet material, specifically a hydride variant of the Sm₂Co₁₇ intermetallic compound. This rare-earth cobalt alloy belongs to the SmCo family of high-performance magnets, engineered for applications requiring exceptional magnetic strength and thermal stability at elevated temperatures. The hydride modification influences the magnetic and structural properties compared to its parent composition, making it relevant for specialized permanent magnet applications where conventional NdFeB magnets are insufficient.

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.
