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.

The thin silicon steel strips are suitable for being used at higher frequencies. The thickness of the silicon steel strips haVE been reduced to the world's thinnest level, reducing the core loss caused by eddy currents. Combined with the insulation coating technology, the lamination factor is improved.

The thin silicon steel strips improve energy consumption and reduce size in high-frequency reactors, transformers, and motors.

The thin silicon steel strips reduce cost and improve the equipment performance at high frequencies.

Note: 1. Tensile strength and elongation are measured parallel to the rolling direction.

          2. Hardness are measured by *1: H;0.5Kg, *2: H;0.3Kg, *3: H;0.1Kg.

1.Thanks to the high permeability, low LH, and high resistivity of silicon steel, the hysteresis loss and eddy current loss are small.

2.Silicon steel requires high plasticity, smooth and flat surface, and low harmful inclusion in order to satisfy the process of punching and shearing, improve magnetic induction, and reduce hysteresis loss.

3.At present, the production process of hot-rolled silicon steel has been eliminated in China and replaced with cold-rolled silicon steel. The iron loss performance of the silicon steel that CUMIC supply far exceeds the iron loss requirements of the international standards.
