Grain Oriented Electrical Steel with 3% silicone is the cream of the crop when it comes to making high-performance motors and transformers. This is because it has high permeability and low hysteresis loss in magnetic fields, which are super important for these applications. Plus, you can customize the size and grade of the silicon steel to fit your specific needs.
Cold-rolled grain-oriented electrical steel can be divided into ordinary grain-oriented silicon steel sheets (GO) and high magnetic induction grain-oriented silicon steel sheets (Hi-B) according to the magnetic properties.

Advantages Of Grain Oriented Silicon Steel
Generally, motors, transformers and other electrical components are required to have high efficiency, low power consumption, small volume and light weight. Electrical steel plate usually takes the core loss and magnetic induction strength as the magnetic guarantee value of the product. The requirements for the performance of electrical steel plate are as follows:
1. Low core loss (PT)
2. High magnetic induction (b)
3. Requirements for magnetic anisotropy
4. Good washability
5. The surface of the steels plates is smooth, flat and uniform in thickness
6. Good insulating film performance
7. Small magnetic aging phenomenon
