Oriented silicon steel is a low-carbon silicon iron alloy with silicon content ranging from 0.5% to 4.5%. It boasts high permeability, reducing Joule loss in power equipment, thus increasing efficiency and offering energy-saving advantages. Additionally, it features lower iron loss and a high resistance coefficient.
Raw Material: Premium CRGO silicon steel sourced from Bao-steel and Wu-steel.
