Other Materials We Provide
In addition to traditional electrical steel, we also offer other special materials to meet the needs of high-end applications:

Amorphous Alloy
Amorphous alloys have extremely low hysteresis loss and high magnetic saturation, making them suitable for high-performance motors such as high-frequency transformers and small efficient motors.

Soft Magnetic Composite
Soft magnetic composites perform excellently in high-frequency motor applications, effectively reducing losses and improving magnetic permeability. We can provide materials such as Somaloy 1P, Somaloy 3P, and Somaloy 5P.

Iron-Cobalt Alloy
Iron-cobalt alloys have high magnetic permeability and high saturation magnetic flux, suitable for high-energy applications such as high-performance motors and electric tools. We offer materials like China’s 1J21, 1J22, 1J27, which are equivalent to Hiperco 50 and Hiperco 27.
Different Motor Applications of Lamination Materials
Different types of motors require different lamination materials. Below are some common applications and the recommended materials:
- Transformers typically use grain-oriented silicon steel, which has low magnetic loss and high saturation magnetic flux, making it ideal for high-power transformers.
- Electric vehicle motor laminations often use non-oriented silicon steel or amorphous alloys, as these materials provide higher efficiency and lower energy consumption, making them ideal for high-efficiency drive systems.
- Ultra-thin silicon steel is widely used in precision motors, such as micro-motors and high-frequency transformers, helping reduce energy loss and improving motor performance.
