About Amorphous Core
Amorphous metals are made utilising rapid solidification technique, which involves cooling molten metal at a pace of one million °C per second to form thin solid ribbons. Because crystalline magnetic anisotropy does not exist, amorphous magnetic metal has a large permeability. Amorphous cores are composed of a thin, 25 µm-thick iron-based ribbon. Wound amorphous ribbon into toroidal and oval shapes. Our improved ribbon increases the amorphous ribbon's cross-sectional area, resulting in ultra-low loss cores. These cores are annealed and impregnated with a specific epoxy, allowing gaps in toroidal cores and cutting ovals in half to make a set of cut C-cores. For multi-phase applications, several oval cores can be coiled and sliced to form E-shaped cores.
Technical Advantage
Amorphous metal cores can operate at 1.56 Tesla, but ordinary ferrite cores can only operate up to 0.49 Tesla of flux saturation (Bsat). When combined with permeability comparable to high-end ferrites and the capacity to manufacture huge core sizes, these cores can be a suitable choice for many of these components
Low losses
When compared to standard crystalline magnetic materials, amorphous magnetic cores exhibit improved magnetic properties, such as lesser core loss. This is because the amorphous structure responds more rapidly to changes in magnetic fields (alternating AC fields) than other materials, resulting in a BH loop with virtually negligible hysteresis losses. Magnetic field variations also cause currents called eddy currents, which are another source of loss.
