Oriented silicon steel is a premium low-carbon silicon iron alloy material with a silicon content ranging from 0.5% to 4.5%. It boasts high permeability, significantly reducing Joule loss in power equipment. This enhancement in efficiency translates to substantial energy-saving benefits. Moreover, it features minimal iron loss and a high resistance coefficient.
Raw Material: We utilize CRGO silicon steel sourced exclusively from industry giants Bao-steel and Wu-steel.
