SmCo2
metal· SmCo2
SmCo2 is a samarium-cobalt intermetallic compound belonging to the rare-earth permanent magnet family, characterized by high magnetic anisotropy and strong magnetic coupling between samarium and cobalt atoms. This material is widely used in high-temperature magnetic applications, including aerospace actuators, oil-well logging tools, and precision instrumentation, where its magnetic properties remain stable beyond the operating limits of ferrite or neodymium magnets. Engineers select SmCo2-based systems when thermal stability, corrosion resistance, and reliability in extreme environments outweigh cost considerations, making it essential for applications in jet engines, satellite systems, and deep-subsea equipment.

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.
