non oriented silicon steel high magnetic strength 440

Because different applications require different properties. For example, transformers require oriented silicon steel, while rotating machinery may be more suitable for non-oriented silicon steel.

2. Costs to consider

Oriented silicon steel tends to be more expensive than non-oriented silicon steel due to the added processing steps.

3. Some efficiency factors

The higher the silicon content, the higher the efficiency because it reduces energy losses. However, too high a silicon content can make the steel more difficult to process.

4. Think About Size
Large equipment components may be better suited to non-oriented silicon steel because it is less sensitive to mechanical strain.

5. Operating Environment
Operating Environment The product operating environment may affect your choice. For example, silicon steel with a higher Curie temperature may perform better in high temperature applications.

Silicon Steel: An Evolutionary Journey

The original soft magnetic material of electrical steel, iron, contains impurities. However, later with the addition of silicon, the resistivity improved significantly. The first is that hysteresis loss is reduced, magnetic permeability is increased, and aging is almost completely eliminated. Today, we see large quantities of oriented silicon steel mainly in power and distribution transformers, but this does not mean that non-oriented silicon steel is not important. Non-oriented silicon steel is widely used in areas where low-cost, low-loss materials are essential, especially in rotating equipment.
