Non-oriented Silicon Steel Features
Low iron loss: The most notable feature of non-oriented silicon steel is its extremely low iron loss (including eddy current loss and hysteresis loss). This is mainly due to the addition of silicon (Si). The addition of silicon increases the resistivity of the material, thereby reducing eddy current losses. At the same time, it also improves the magnetic domain structure of the material and reduces the hysteresis loss.
Good permeability: Although it is called “non-oriented”, it still shows relatively uniform permeability in multiple directions. This helps maintain stable working efficiency in complex electromagnetic field environments.
Good machinability: It has good ductility and machinability, and is easy to cut, press and weld. This can meet the electromagnetic core manufacturing needs of different shapes and sizes.
Suitable strength and toughness: While ensuring electromagnetic properties, it also has sufficient strength and toughness. In this way, it can withstand the mechanical and thermal stress during the operation of electromagnetic equipment.
Good thermal stability: In high temperature environment, it can still maintain low iron loss and stable magnetic properties.
Low coefficient of thermal expansion: Compared with other metal materials, its coefficient of thermal expansion is low, helping to reduce the size change and performance fluctuations caused by temperature changes.

Application Field
1. Electric power industry
Transformer manufacturing: It is the core material for the manufacture of power transformer core. Its low iron loss (that is, low energy loss) and high permeability characteristics make the transformer more efficient at converting electrical energy during operation. This can reduce energy waste and improve grid efficiency.
Motor manufacturing: Although the application of non-oriented silicon steel in motors is not as common as oriented silicon steel (the latter is more suitable for rotary motors), it can also play its role in certain types of motors, especially in small and medium-sized motors used in specific conditions, and improve the energy efficiency ratio of the motor.
2. New energy industry
Wind power: With the rapid development of renewable energy, wind power is one of the important forms of clean energy. The manufacture of the generator set also requires the use of non-oriented silicon steel. Efficient iron core materials can improve the conversion efficiency of wind turbines and increase power generation.
Electric vehicles: In the field of electric vehicles, key components such as inductors and transformers in drive motors and on-board chargers are also often used as core materials. This can improve energy efficiency and extend the range of electric vehicles.
3. Home appliance industry
It is also widely used in the field of home appliances, especially the compressor motor in household appliances such as refrigerators and air conditioners. The core material requirements of these motors include low iron loss, high heat resistance and good processability, and non-oriented silicon steel is the ideal choice to meet these requirements.
