1J50 Soft magnetic alloy 1J79 1J77 1J85 permalloy 0.015~2.5mm
Factory Customization super permalloy wire
Product brief introduction
1J50 is a kind of nickel-iron soft magnetic alloy which has high
initial permeability and maximum permeability with low coercive
force and high saturation magnetic induction strength. It is
usually used in saturable reactors, high gain magnetic amplifiers,
biostable switching devices, and power inverter-converter
applications.
