Permanent Samarium Kobalt Magnete SmCo Magnéit
Produit Beschreiwung
Samarium-Kobalt Magnete (SmCo) hunn dee beschten Br Temperaturkoeffizient (-0,035% / ℃) déi absolut méi héich verfügbar Induktioun iwwer 150 ℃ Aarbechtstemperatur gëtt. Trotz méi héije Käschte wéi aner magnetesch Materialien, bitt SmCo eng aussergewéinlech Kombinatioun vun héijer Energie, thermescher Stabilitéit a Korrosiounsbeständegkeet. Schutzbeschichtungen sinn allgemeng net erfuerderlech ausser fir speziell Uwendungen. Awer SmCo ass ganz knusprech a fragil: wann Dir et fällt, brécht et.
