1J85, 1 J86 are soft magnetic alloys with high initial permeability.
Typical properties: 1, high or very high initial permeability and maximum permeability, 2, very low coercivity, 3, low saturation magnetic induction.
They are commonly used in the manufacture of: high sensitivity low power transformers for low magnetic field operation, low power magnetic amplifiers, relays, chokes, magnetic head cores for magnetic recording devices, magnetic shields, micromotors for electronic watches, current transformers, telephone transformers, leakage circuit breakers, relay parts for leakage circuit breakers, a variety of band-wound cores, cut cores, and laminated cores.
