Temperature compensated magnetic alloys

Precision Alloy 1J30/1J31/1J32/1J33/1J38

Temperature compensated magnetic alloys

Note:
In instrument such as anemometer and electric meter, the compensation ability of magnetic temperature compensation materials to the permanent magnets determines the apparatus s accuracy.
