Product Details


High permeability soft magnetic alloy mainly nickel base alloy, nickel content is over 75%, this kind of alloy has the very high initial permeability and permeability.Often referred to as permalloy, also known as the early high magnetic conductivity alloy.They all have good processing performance, can be rolled into thin strip.Flat Soft Magnetic Wire is suitable for application in the ac weak magnetic field.Such as TV and instrumentation in various audio transformer, the high accuracy bridge transformer, transformer, magnetic shielding, magnetic amplifier, magnetic modulator, audio head, choke, precision electric meter of the piece and piece, etc

Ni79Mo4 widely used in radio-electronic industry, precision instruments, remote control and automatic control system.
