Product Description
Oriented silicon steel, a low-carbon silicon iron alloy, boasts a silicon content ranging from 0.5% to 4.5%. It offers remarkable attributes such as high permeability, which significantly reduces Joule loss in power equipment, thereby enhancing efficiency and delivering notable energy-saving benefits. Additionally, it features lower iron loss and a high resistance coefficient.
Raw material: CRGO silicon steel sourced from Baosteel and WISCO
