Electrical steel, also known as silicon steel or laminated steel, is a special type of steel with excellent magnetic properties. It can be used in various electromagnetic applications. Its typical composition includes iron and a range of silicon contents, with carbon and impurities being reduced to a minimum level. This type of steel is usually supplied in sheet form for lamination, where multiple steel plates are stacked together and insulated from each other.

Electrical steel is suitable for use in power transformers, electric motors, generators and other electrical equipment because of the highly efficient magnetic properties of this combination of elements. Electrical steel is usually made in an electric arc furnace and then processed into sheet form for use in laminated transformers. In the following chapters, we will introduce the composition, properties and uses of electrical steel in more detail, clarifying its important position in contemporary electrical engineering.

What are the advantages of electrical steel?

Electrical steel has unique properties that offer distinct advantages:

More cost-effective than some advanced magnetic materials, making it a practical choice for a variety of applications, including transformers and electric motors. Materials such as neodymium iron boron (NdFeB) magnets have excellent magnetic strength but are much more expensive than electrical steel.
Durable and able to withstand mechanical stress, suitable for applications where mechanical strength is critical.
The core has low losses, which means it dissipates very little energy as heat when acted upon by a magnetic field, helping to improve energy efficiency.
