We produce a wide variety of magnetic powders.
These powders are of varying composition and of varying size distribution
and widely used for sintered magnet and dust core.In particular,we can
produce super fine powder having diameter of less than 10µm and also
amorphous powder by super rapid cooling (more than 106K/s).
These powder are best suited for higher frequency,higher current application.
