1J50 Iron - Nickel Alloy Strip Permalloy Strip With High Magnetic Permeability
Product Description
Permalloy refers to an iron-nickel alloy, also known as a soft magnetic alloy. Its nickel content ranges from 35% to 90%. The biggest feature of permalloy is its high weak magnetic field permeability. Their saturation magnetic induction is generally between 0.6--1.0T.
The alloy is smelted in a vacuum induction furnace, and is made into cold-rolled strip, cold-drawn wire or hot-rolled (forged) sheet and bar through hot-cold plastic deformation.
Used to make audio transformers, transformers, magnetic amplifiers, magnetic modulators, chokes, audio heads, etc.
My country's permalloy grade is 1JXX. Among them, J means "precision alloy", "1" means soft magnetism, and the number on the back permalloy surface is the serial number, which usually indicates the nickel content in the alloy. For example 1J50, 1J851 and so on. Permalloy has high magnetic permeability, so it is often used in the iron core of medium and high frequency transformers or devices with strict requirements on sensitivity, such as high frequency (tens of KHz) switching power supply transformers, precision transformers, leakage switch transformers, Magnetic shield, yoke, etc.
