Robust core for high-power applications requiring thermal stability and precision.
Lightweight, high-efficiency components for advanced motor and generator designs.
Amorphous alloys are non-crystalline metallic materials with a disordered atomic structure, offering extremely low core losses and high magnetic permeability. They are ideal for high-efficiency transformers and inductors.
Nanocrystalline materials consist of ultra-fine crystalline grains (typically 10–20 nm), combining the best properties of amorphous and crystalline materials—high saturation flux, excellent temperature stability, and ultra-low coercivity.
These advanced materials are critical in modern power electronics, enabling smaller, lighter, and more efficient components for EVs, renewable energy, and smart grid systems.
