Semi-finished products - EI silicon steel lamination
EI silicon steel lamination is a type of magnetic material made by laminating thin sheets of silicon steel to create a core for electrical transformers and other electromagnetic devices. The EI designation refers to the shape of the core, which consists of two E-shaped pieces and one I-shaped piece.
The key advantage of EI silicon steel laminations is their high magnetic permeability, which allows them to efficiently transfer electrical energy between two coils. They also have lower core losses, which means that they save more energy as heat during operation.
Price of EI lamination varies depending on factors such as steel raw material quality, production volume, and market competition.
