High-alloyed Fe6.5Si is mainly used for soft magnetic high-frequency applications in so called dust-cores. The powder is difficult to compact and requires high pressures (1000-2000 MPa) and simple shapes. More common is use of the powder un-compacted, admixed in an insulating binder material to form a component. Excellent DC Bias performance, good temperature stability, high saturation flux density, low magnetostriction (low noise).
