Silicon Steel Coil

Silicon steel, also known as electrical steel, lamination steel, or transformer steel, is a ferritic alloy of iron and silicon that have magnetic properties, which make it useful in motors and transformers. This type of steel material contains 0.5%-4.5% silicon in weight with low carbon of less than 0.08%. The addition of silicon (Si) improves the magnetic softness and increases the electrical resistivity of steel. There are two forms of silicon steel: grain-oriented (GO) and non-oriented (NGO). GO silicon steel can be further subdivided into regular grain-oriented (RGO) and high permeability grain-oriented (HGO) materials. Silicon steel is known for its high permeability and low amounts of core loss, which make it useful in the generation, distribution, and consumption of electricity, such as small to large motors, relays, solenoids, appliances’ motors, wind turbines, cores of transformers, EV, and power generator equipment, etc.
