Physical properties
Magnetic properties
1J79 alloy saturation magnetic induction Bs≥0.75T, Curie point ℃ = 450, Resistivity (μΩ • m) = 0.55; having small Magnetostrictive coefficient, Easy permeability, Fast demagnetization, small Coercive force, Low eddy loss, be used covering frequency, medium to high frequencies over the entire frequency range, Products include: strip, sheet, bar, wire and foil. Mainly used for switching power transformers, Precision transformer, Leakage switch transformer, Magnetic shielding, Yoke and weak magnetic field applied high sensitivity small power transformer zero-sequence power transformer, Low-power magnetic amplifiers, high frequency power.
Application: Pulse transformer, Relays, Transformers, Magnetic amplifier, Electromagnetic clutch, Choke core and magnetic shielding, Automotive sensors.
We can control the temperature of the heat treatment in order to achieve customer requirements permeability.
