1J30, 1J31, 1J32, 1J33, 1J38 soft magnetic alloy features:
This is a type of low Curie temperature (25 ° C ~ 200 ° C) alloy, and its outstanding feature is that below the Curie temperature, the magnetic induction value decreases sharply with increasing temperature, and has a nearly linear relationship.
1J30, 1J31, 1J32, 1J33, 1J38 soft magnetic alloy applications:
It is usually used for magnetic branch temperature, compensation element or temperature sensing element in traveling wave tube, magnetron, wind direction and air permeability meter, voltage regulator, odometer, gasoline meter, electricity meter, etc. using permanent magnets.
