· JVASP-111788· PrSmCo17

PrSmCo17 is a rare-earth cobalt-based permanent magnet alloy combining praseodymium and samarium with cobalt in a 1:17 stoichiometric ratio, belonging to the SmCo family of high-performance magnets. This material is used in demanding applications requiring strong magnetic performance at elevated temperatures and in corrosive environments, particularly in aerospace, defense, and specialized industrial equipment where conventional ferrite or NdFeB magnets would degrade. PrSmCo17 offers superior thermal stability and corrosion resistance compared to neodymium-iron-boron magnets, making it the preferred choice when reliability and performance consistency across wide temperature ranges are critical.

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.
