sendust

Record heads are constructed of laminated permalloy, ferrite, or sendust.

The high frequency ranges are based on a Sendust core material, which has low magnetostriction, resulting in low acoustic noise.

Almag powder magnetic cores in MPP, Hi Flux, sendust and iron powder.

Due to its chemical composition and crystallographic structure Sendust exhibits simultaneously zero magnetostriction and zero magnetocrystalline anisotropy constant K.

A student of Kotaro Honda, Masumoto developed a magnetic metal powder Sendust in 1936, and was the winner of the Imperial Prize of the Japan Academy in 1946.
