Oriented silicon steel is a superior low-carbon silicon iron alloy with a silicon content of 0.5% to 4.5%. It boasts high permeability, greatly reducing Joule loss in power equipment, thus enhancing efficiency and promoting energy savings. Furthermore, it features lower iron loss and a high resistance coefficient.
Raw Material: Premium CRGO silicon steel sourced from Baosteel and WISCO.
