Products Description

Ni80Mo5  Permalloy refers to an iron-nickel alloy with a wide range of nickel content, ranging from 35% to 90%. The biggest feature of Permalloy is its high magnetic permeability in weak magnetic fields. Their saturation magnetic induction intensity is generally between 0.6-1.0T.

1J85 alloy is smelted in a vacuum induction furnace. After being cast into a steel ingot, it is hot forged into a slab, then after hot rolling, pickling, and surface finishing, it is cold rolled into a finished strip or forged into the required bar. Most of these alloys are said to be used under alternating magnetic fields. They are mainly used for high-conductivity yoke irons, sensitive relays, low-loss micromotors, low-power power transformers, pulse transformers, transistor switches, magnetic amplifiers, magnetic modulators, and sensitive signals. Input and output transformers, magnetic sensors of aviation magnetic heading instruments, magnetic sensitive components in magnetic measuring instruments, moving and stators in precision electric meters, magnetic shielding and magnetic temperature compensation components.
