1j79 Soft Magnetic Alloy Tube Permalloy Pipe 79hm Permalloy Soft Magnetic Alloy tube Ni79mo4
1. Description 1J79 (Soft magnetic alloy) (Common Name: Ni79Mo4, E11c, malloy, permalloy, 79HM) Precision Soft Magnetic Alloy is one kind of alloy with high permeability and low coercivity in weak magnetic field. This kind of alloy is widely used in radio electronics industry, precision instruments, remote control and automatic control system, generally, it is mainly used in energy conversion and information processing. 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.Alloy 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 Chemical Content(%)
Thermal Expansion Coefficient (20~100ºC)
Volume Resistivity (20ºC)
