Product Description
Oriented silicon steel is a low-carbon silicon iron alloy material with a silicon content of 0.5%~4.5%, which has characteristics such as high permeability(which can reduce Joule loss in power equipment, improve efficiency and energy-saving effects), lower iron loss and high resistance coefficient.
Raw material:CRGO silicon steel from Bao-steel and Wu-steel.
