Amorphous iron core is a machine part made of iron-based amorphous strip, with a crystallization temperature of 550 degrees.
Various transformer cores, such as aviation transformers, railway control system transformers, mechanical parts quenching equipment transformers, laser power transformers, etc.
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:
|Saturation magnetic induction intensity Bs||1.56T||Residual magnetic induction||≥0.8|
|Curie temperature||410℃||Coercivity, A/m||<4|
|Crystallization temperature||550℃||Loss (400Hz, 1.0T), W/kg||<15|
|Saturation magnetostriction coefficient||27x10-6||Loss (400Hz, 0.5T), W/kg||<1.5|
|Maximum permeability||>20×104||Loss change rate (-50~130℃)||<15%|
|Transverse magnetic annealing||Magnetic-free annealing||Longitudinal magnetic field annealing|
|Saturation magnetic induction||1.5 T||1.5 T||1.5 T|
|Residual magnetic induction||<0.5 T||1.0 T||1.2 T|
|Loss (50Hz, 1.4T)||<0.2W/kg||<0.13W/kg||<0.3W/kg|
|Loss (400Hz, 1.2T)||<1.8W/kg||<1.25W/kg||<2W/kg|
|Loss (8kHz, 1.0T)||<80W/kg||<60W/kg||<100W/kg|
|Iron loss rate of change (-55 oC-125 oC)||<15%||<15%||<15%|
