Magnetau SmCo Samarium Cobalt Parhaol
Disgrifiad o'r Cynnyrch
Mae gan magnetau Samarium-Cobalt (SmCo) y cyfernod tymheredd Br gorau (-0,035% / ℃) sy'n rhoi'r anwythiad absoliwt uwch sydd ar gael uwchlaw tymheredd gweithio 150 ℃. Er gwaethaf cost uwch na deunyddiau magnetig eraill, mae SmCo yn darparu cyfuniad rhagorol o ynni uchel, sefydlogrwydd thermol, a gwrthsefyll cyrydiad. Yn gyffredinol nid oes angen haenau amddiffynnol ac eithrio ar gyfer cymwysiadau penodol. Ond mae SmCo yn grimp ac yn fregus iawn: os byddwch chi'n ei ollwng, bydd yn torri.
