Samarium Kobalt Magnets (SmCo Magnet)
produkt Omskriuwing
Samarium-kobaltmagneten (SmCo) hawwe de bêste Br temperatuerkoëffisjint (-0,035% / ℃) dy't de absolute hegere beskikbere induksje boppe 150 ℃ wurktemperatuer ferlient.Nettsjinsteande in hegere kosten as oare magnetyske materialen, SmCo biedt in treflike kombinaasje fan hege enerzjy, termyske stabiliteit, en corrosie ferset.Beskermjende coatings binne oer it algemien net fereaske, útsein foar bepaalde tapassingen.Mar SmCo is heul skerp en breklik: as jo it falle, sil it brekke.
