sintered Alnico magnet

Alnico magnets are made from aluminum, nickel, cobalt, copper, iron, titanium and other element. There is cast or sintered Alnico magnet due to different process craft.

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 ℃.
Alnico permanent magnet products are widely used in various instruments and other applications.
Shortcoming: the coercivity is very low (typically less than 140kA / m), demagnetization curve is nonlinear. Alnico magnets easily magnetized, also easy to demagnetization.

Applications:
instrumentation,
communications,
magnetic switches
variety of sensors.
Controls
Generators
Receivers
Telephones
Microphones
Bell ringers
Loudspeakers
