Cold-rolled oriented silicon steel
Product Details: Silicon steel, also known as electrical steel, lamination steel, or transformer steel, is a ferritic alloy of iron and silicon. It contains 0.5%-4.5% silicon by weight and less than 0.08% carbon. It is available in grain-oriented (GO) and non-oriented (NGO) forms. GO silicon steel can be further subdivided into regular grain-oriented (RGO) and high permeability grain-oriented (HGO) materials. It is used in the cores of transformers, motors, generators, and other electrical devices due to its high magnetic permeability, low core loss, and high electrical resistivity[1][2][4].
