The 1J50 has rectangular hysteresis loop and high saturation magnetic induction, is mainly used to work at a moderate magnetic field magnetic amplifier, choke ring, rectifier circle, as well as the computer device components.
1J79 has a high initial permeability, to work in a weak magnetic field of various transformers, transformers, magnetic amplifiers, choke coil core and magnetic shielding.
3J53 has a low temperature coefficient of frequency in the range of -40 °C ~ 80 °C for mechanical filter orthography, relay reed, then vibration components.
4J29 (F15) having similar coefficient of linear expansion with hard glass within a certain temperature range, applied to vacuum industry to match hard glass.
