Sendust

[′sen‚dəst] (materials) The trade name for an alloy consisting of approximately 85% iron, 6% aluminum, and 9% silicon; its powdered form is compacted to manufacture low-loss magnetic cores.

Sendust

an iron-based alloy (optimum composition, approximately 85 percent Fe, 9.6 percent Si, 5.4 percent Al) characterized by high magnetic permeability (μ₀ up to 35,000; μ_max up to 100,000), electrical resistivity (approximately 80 microohm·cm), and mechanical hardness. It is classed as a softmagnetic material. Sendust was developed in the 1930’s in Japan and is known in the USSR by the name alsifer.

Sendust is brittle and can be easily ground into powder which, when mixed with a dielectric binder, is the base material from which magnetodielectrics are pressed. The magnetodielectrics are used in radio engineering and communications technology as cores for transformers and choke coils of high stability. In cast form, Sendust is used in the manufacture of pole pieces for tape recorders.
