Sintered aluminum nickel and cobalt:
It uses the powder metallurgy method to make, easy to process small size and easy to control the tolerance, suitable for complex shape, light, thin, small products.
but the magnetic properties is lower than the cast AlNiCo,
The advantages of the Alnico magnet remanence (up to 1.25T), low temperature coefficient. The temperature coefficient of -0.02% / ° C, while the maximum operating temperature up to about 450 ℃.
