*Feature
Thermo-magnetic compensation alloys are provided with low curie temperature between 25~200℃. Their outstanding characteristics are those magnetic induction decreases dramatically with the increase of temperature under curie temperature, and the magnetic induction is almost linear with temperature.
*Application
Thermo-magnetic compensation components or thermal sensor used in traveling wave tube, magnetron, voltage regulator, gasoline gauge, watt-hour meter and speed milometer, etcs.
