2021-10-25

Amorphous core

amorphous core

Amorphous iron core is a machine part made of iron-based amorphous strip, with a crystallization temperature of 550 degrees.

Application field

Various transformer cores, such as aviation transformers, railway control system transformers, mechanical parts quenching equipment transformers, laser power transformers, etc.

Performance characteristics

It is made of iron-based amorphous strip material, which has high saturation magnetic induction and low loss, which can greatly reduce the weight of the equipment, reduce the volume, and improve the efficiency. Performance

The magnetic properties are as follows:
