Cast Alnico
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. Because of high hardness, it¡¯s only fit for grind. Casting Alnico magnets are suitable for being used in instrument, meter, micro-motor, electro-acoustic device, microwave device and magnetic drive unit etc.
