Samarium Cobalt (SmCo) Magnet
Samarium cobalt (SmCo) magnets are a type of rare-earth permanent magnet material. They are produced by proportioning samarium, cobalt and other rare-earth metals, smelting them into alloys, then pulverizing, compacting and sintering.
They feature high magnetic energy product and an extremely low temperature coefficient, with a maximum operating temperature of up to 350°C and no lower temperature limit.
At operating temperatures above 180°C, their maximum magnetic energy product (BHmax), coercivity, temperature stability and chemical stability all surpass those of NdFeB permanent magnets.
Samarium cobalt magnets are available in two composition ratios: samarium‑to‑cobalt atomic ratios of 1:5 and 2:17.
