Sendust

Sendust

Sendust is a magnetic metal powder that was invented at Tohoku Imperial University in Sendai, Japan, about 1936 as an alternative to permalloy in inductor applications for telephone networks. Sendust composition is typically 85% iron, 9% silicon and 6% aluminum. The powder is sintered into cores to manufacture inductors. Sendust cores have high magnetic permeability, low loss, and good temperature stability.

Sendust is harder than permalloy, and is thus useful in abrasive wear applications such as magnetic recording heads.
