Nanocrystalline E Shape Transformer Core Product Description
Amorphous alloy is a new soft magnetic material. It is known as a new material with environmental protection, energy saving and high efficiency. It is produced through an advanced technology of rapid solidification of molten metal at a cooling rate of about a million 'C/sec.



Nanocrystalline E Core Feature
High saturation magnetic induction intensity
Nanocrystalline materials have a relatively high saturation magnetic induction intensity, generally ranging from 1.2T to 1.5T. They can store more magnetic energy in a smaller volume, thereby effectively reducing the size and weight of the transformer.
High magnetic permeability
Its initial magnetic permeability is usually above 10,000, and can be as high as 80,000 or even more. This enables the nanocrystalline E-shape core to generate a high magnetic induction intensity under a low magnetic field strength, improving the efficiency of the transformer and reducing the excitation power and copper loss.
Low loss
Nanocrystalline cores have low hysteresis loss and eddy current loss at high frequencies, which can reduce the temperature rise of the transformer and enhance its operational stability and reliability.
Excellent temperature stability
Nanocrystalline materials have a high Curie temperature, generally around 570°C. Within the temperature range of -55°C to 130°C, the change rate of their main magnetic properties is less than 10%, showing good temperature stability.
Nanocrystalline alloy Core Application
- Inverter power supplies: Such as inverter welding machine power supplies, electrolytic plating equipment, induction heating equipment, etc. The nanocrystalline E-shape core can meet the working requirements of these devices under high-frequency and high-power conditions, improving the efficiency and power density of the power supply.
- Communication power supplies and UPS power supplies: In communication power supplies and UPS power supplies used in places like communication base stations and data centers, the nanocrystalline E-shape transformer core can effectively reduce the loss of the power supply, improve its stability and reliability, and ensure the normal operation of the equipment.
- Other fields: It can also be applied in X-ray machine power supplies, laser power supplies, variable frequency speed control power supplies and other fields to provide efficient and stable magnetic performance support for these devices.
