Silicon steel
Silicon steel is an iron‑silicon soft‑magnet alloy with silicon added to reduce core loss and boost magnetic permeability. Commonly used in power grid, new‑energy vehicle and electrical equipment fields.
Non-oriented Electrical Steel
The 50W1300 CRNGO steel transformer core laminate material is a transformer core composed of multiple layers of high-performance magnetic steel sheets. It is a special type of silicon steel with excellent magnetic properties and low energy consumption. It is primarily composed of silicon, iron, and small amounts of carbon, manganese, and other elements. With its high permeability and low hysteresis loss, it is widely used in power transmission and conversion.
