Oriented silicon steel is a high-efficiency, low-carbon silicon iron alloy with a silicon content between 0.5% and 4.5%. Renowned for its high permeability, it significantly reduces Joule loss in power equipment, thereby enhancing efficiency and saving energy. Additionally, it boasts lower iron loss and a high resistance coefficient.
Raw Material: Premium CRGO silicon steel sourced from industry leaders Bao-steel and Wu-steel.
