Rectangular Amorphous Bare Cut Core
Rectangular Amorphous Bare Cut Core

Our rectangular amorphous bare cut cores (split cores) have the advantage of low core loss and high operation flux density, thus, they can replace Metglas AMCC FINEMET F3CC series cut cores made by Hitachi Metals. We can also design and manufacture customized split nanocrystalline cores of different sizes.
