SmYCo10
metal· JVASP-137346· SmYCo10
SmYCo10 is a samarium-yttrium-cobalt permanent magnet alloy, part of the rare-earth cobalt magnet family that emerged as a high-performance alternative to earlier ferrite magnets. This material is valued in aerospace, defense, and precision instrumentation for applications requiring strong magnetic fields in compact, thermally stable packages, particularly where operating temperatures exceed the limits of neodymium-iron-boron magnets or where corrosion resistance and long-term reliability are critical.

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.
