Packging & Delivery

Iron based amorphous Ribbon are composed of 80%Fe, 20%Sic and B type metal elements

Amorphous Ribbon is an new soft magnetic material.

It has the common material property of soft magnetic, like low coercivity(Hc), high saturaion flux density(Bs), low loss(Ps), and high stability.

New Soft MagneticSolution

Amorphous aremainly used to replace silicon sheet:

Amorphous canreduce the fe-loss by 60-70%

Work frequencybetween 50Hz to 10KHz

Lowerloss: 1/3 to 1/5 of silicon sheet
