Fe-based Nanocrystalline Alloy Strip

Introduction:

Fe-based Nanocrystalline alloy strip with Fe, Si, Nb, B, Cu ingredients, and the nanocrystalline materials have high saturation magnetic induction, high permeability, low coercivity, low loss and good stability, wear resistance, corrosion resistance and other excellent properties.

As the best performance-to-price ratio of nanocrystalline alloy materials, it can replace silicon steel, permalloy and ferrite to become the ideal raw materials for medium and high frequency transformers, current transformers and inductors.

Benefits：

• The nanocrystalline alloy ribbon with High Saturate induction (1.25T) and High initial magnetic permeability(＞80000), which can meet the design of high frequency,miniaturization and low cost.
• Nanocrystalline alloys with low core loss as 50w/kg at 100KHz, 300mT, and it reduces the temperature rise very well.
• The coercive force (Hc) could lower as 1.5A/m, and the efficiency of components could be improved.
• The saturation magnetostriction close to zero, so it can lower the working noise effectively.
• The magentic properties of nanocrystalline alloys is stable, and the rate of change less than 10% at -50℃~150℃.
• The nanocrystalline alloys has the excellent magnetic permeability and high impedance characteristics in a wide range of frequency.
• Besides, it is flexible to control the magnetic properties B-H curve by the magneti-field annealing, which could meet the customer’s requirements.
