Conventional silicon steels are widely used for electrical power apparatus, electrical components in industrial products and home electronics. However, most silicon steel strips are thicker than 0.20mm and applied only to apparatus operated at industrial frequencies.

On the other hand, thin-gauge silicon steel strips have advantage for use at higher frequencies. The thickness of the silicon steel strips have been reduced to the world's thinnest level so that the core loss caused by eddy currents is combined with the insulatioin coating technology of steel manufacturer, the lamination factor has been improved. 

Thin-gauge silicon steel strips assist saving energy and down-sizing high frequency reactors, transformers and motors.

Thin-gauge silicon steel strips allow superior cost saving as well as performance at high frequencies.


Characteristics


■ Low Core Loss

   They have low core loss at high frequencies and allow improvements in efficiency, and saves energy of reactors and transformers.


■ High Permeability

   High permeability allows use for shields.


■ High Saturation Flux Density

   They contribute to down-sizing of high frequency reactors and transformers due to high saturation flux density.


■ Excellent insulation coating

   The inorganic coating allows excellent insulation, which enables the best stress relief annealing (results).
