SmCo Magnets
High-temp choice · Operating temp up to 350°C · 1:5 and 2:17 series
DESCRIPTION
Samarium-cobalt magnets outperform NdFeB on temperature stability and corrosion resistance, common in aerospace, downhole tooling, and automotive high-temp motors. SmCo5 (1:5) covers standard high-temp duty; Sm2Co17 (2:17) handles ultra-high temperature (working temp up to 350°C). Exports involving aerospace or military-adjacent end-use require an end-use declaration upfront.
