The material selection of transformer iron cores has a crucial impact on their performance. Currently, the commonly used material is silicon steel sheets. Silicon steel sheets are made by adding a certain amount of silicon to iron. The addition of silicon can increase the resistivity of iron and reduce eddy current loss. According to different manufacturing processes, silicon steel sheets can be divided into hot-rolled silicon steel sheets and cold-rolled silicon steel sheets. Hot-rolled silicon steel sheets have lower costs but relatively poor magnetic properties, and are mostly used in small and medium-sized transformers; cold-rolled silicon steel sheets are further divided into oriented silicon steel sheets and non-oriented silicon steel sheets. Oriented silicon steel sheets have excellent magnetic properties, with high magnetic permeability and low loss in specific directions, and are widely used in large power transformers; non-oriented silicon steel sheets have relatively uniform magnetic properties and are often used in motors and small transformers and other fields. In addition to silicon steel sheets, in some special occasions, such as high-frequency transformers, materials such as ferrites are also used. Ferrites have high magnetic permeability and high resistivity, which can effectively reduce losses at high frequencies.
