Silicon Steel is a silicon iron alloy with a silicon content of 3%~ 5%. Divided into oriented silicon steel and non-oriented silicon steel, also known as electrical steel, silicon electrical steel, lamination steel, relay steel, or transformer steel is specialty steel with silicon added to it, which improves its electrical resistivity and magnetic properties, and reduces hysteresis loss.
