SmCo ak alnico, ak mayetis pi fò pase leman ferit ak rezistans ekselan kont korozyon ak tanperati ki wo, yo se de ideyal materyèl yo mayetik pou akoupleman. Men tou, gen tou yon ensifizans siyifikatif nan SmCo ak Alnico materyèl: segondè pri materyèl anvan tout koreksyon.

SmCo and alnico, with stronger magnetism than ferrite magnets and excellent resistance against corrosion and high temperature, are the two ideal magnetic materials for couplings. However, there is also a significant shortcoming of SmCo and Alnico material: high raw material price.
