Amorphous Bars

Amorohous bas & Amorphous Block Core – SUNBOW's amorphous-SWAM & nanocrystalline-SWNA alloys are based on Fe, Si, B and with further additions of Nb and Cu, and produced by rapid solidification technology.

Composition metals melt in furnace under around 1500℃, and turn into liquid metal which pass through a narrow nozzle, and solidify at rate of 1million degree/s. Atoms have no enough time to reach microstructure-crystalline state and stay in amorphous state.

A subsequent heat treatment-annealing at around 500~600℃ transforms the initially amorphous microstructure into nanocrystalline state in which fine crystalline grains (average grain diameter of 10-40 nm) embedded in an amorphous residual phase.

Application:High-power (especial more than 50KW) reactors of solar or wind inverters.

power transformer, high speed motor (rotor & stator), welding machine, induction heating, medical equipment (X-ray & CT), inductor and reactor (EV/HEV/FCV-Bulk & Boost, solar & wind-inverter, automation-converter & UPS, military)

>Thickness (24μm) - smaller eddy & loss

>Coercivity (2.4A/m) - smaller hysteresis loss

>High Frequency(≤20KHz) - wider working range

>Big Saturation Flux Density (1.56T)- smaller dimension and less weight

Other sizes can be customized .
