Silicon steel sheets and coils are essential materials in transformer manufacturing. Based on their characteristics and applications, they are classified as follows:

1. Silicon steel sheets are primarily divided into hot-rolled and cold-rolled types. Hot-rolled silicon steel sheets possess good magnetic permeability and are widely used in motors, electrical appliances and other fields; cold-rolled silicon steel sheets, on the other hand, are characterised by high magnetic flux density and low loss, and are commonly used in high-performance electronic equipment.

2. Silicon steel coils are classified into multiple grades based on silicon content, thickness, width and other factors. These include high-, medium- and low-silicon steel coils, as well as ultra-thin, standard and thick-gauge coils. Furthermore, there is a distinction between grain-oriented and non-grain-oriented silicon steel coils; the former possesses directionality, whilst the latter does not.
