Small changes in magnetic properties to temperature effects,Excellent temperature stability temp. coefficient of Br is the smallest among all of the other permanent magnets.
Casting Alnico magnets are suitable for being used in instrument, meter, micro-motor, electro-acoustic device, microwave device and magnetic drive unit etc.
Casting Alnico magnets possesses high magnetic density and great time stability and low coefficient of temperature ,so under the quick change of temperature the demagnetization is low
