Temperature compensated soft magnetic alloys
Temperature compensated soft magnetic alloys
Brands: 1J30, 1J31, 1J32, 1J33, 1J38
Standard: GB/T15005-94
Characteristics:
This alloy has a lower Curie temperature, generally between 100-200 ℃. When the temperature approaches the Curie temperature, the magnetic induction intensity B value will rapidly decrease as the temperature rises. Within the ambient temperature range, the magnetic induction intensity changes sharply with temperature changes, which can compensate for the magnetic error caused by temperature in permanent magnets.
Application:
Suitable for magnetic shunt compensation components, anemometers, temperature switches, high-performance gyroscopes, automotive speedometers, combination instruments, sensors, etc. in electromagnetic and permanent magnet circuits.
