Oriented silicon steel, a refined low-carbon silicon iron alloy with 0.5% to 4.5% silicon content, offers exceptional permeability, significantly minimizing Joule loss in power equipment. This heightened efficiency translates to substantial energy-saving benefits, featuring reduced iron loss and a high resistance coefficient.
Premium Raw Material: We exclusively utilize CRGO silicon steel sourced from Baosteel and WISCO, ensuring top-notch quality.
