We can provide custom strip materials of various specifications based on customers' needs.
Features
- This amorphous alloy has high saturation magnetic induction intensity, so it uses less strip material under the same magnetic induction intensity to make its size smaller.
- Fe based amorphous alloy has high magnetic permeability and low coercive force, which can improves the efficiency of transformer when being used in transformer.
- This amorphous alloy has low loss, and the loss rate is only 1/3-1/5 to that of the silicon steel sheet, which can reduce the temperature rise of transformer.
- The low magnetizing current can reduce the copper loss of the primary coil in the transformer.
- This alloy has good stability, making it able to work below 130℃ for long time.
