Product Description

1j31 Magnetic temperature compensation Soft Magnetic Alloy strip

Magnetic temperature compensation Soft magnetic alloy

Some soft magnetic materials in the near the Curie point, under a certain magnetic field of magnetic induction intensity and saturated magnetic induction intensity varies with temperature change quickly.If using the environment temperature close to the Curie point temperature and the temperature range of alloy magnetic induction intensity along with the change of temperature close to the line, you can take advantage of the characteristics of magnetic temperature compensation for the temperature error of instrumentation electromagnetic system, is used to eliminate or change such as non-contact temperature controller, the thermal relay parts and voltage regulator assembly instrument by the relationship between reading and temperature

The above 1 j30, j31, 1 j32 belongs to iron nickel binary alloy, the Curie point and magnetic induction intensity - temperature curve is very sensitive to the alloy composition.Nickel content changes with the carbon content of 0.1% or 0.01%, the Curie temperature is 5 ºC, and 65 ºC below zero in the structure and performance of irreversible changes will take place here, so the production and use of these alloys were required to be strictly controlled.Its temperature is - 55 ~ 70 ºC, it is mainly used for traveling wave tube, magnetron, etc
1 j33 alloy using temperature range for - 40 ~ 80 ºC, it is mainly used for voltage regulator.
1 j38 alloy using temperature range for 40 ~ 60 ºC, it is mainly used for electricity meter and automobile instrument.

Soft magnetic alloy are in weak magnetic field with high permeability and low coercive force of alloys.This kind of alloy are widely used in radio electronics, precision instruments and meters, remote control and automatic control system, the combination is mainly used for energy conversion and information processing, the two aspects of is an important material in the national economy.

2.Usage 
It is mostly used in small transformers, pulse transformers, relays, transformer, magnetic amplifier, electromagnetic clutch,the reactor coreand magnetic shielding which work inweak magnetic orsecondary magnetic field.
