1, Alnico magnet material is made by alloying aluminum, nickel and cobalt with iron.

2, Some grades also contain copper and/or titanium. The alloying process is casting or sintering.

3, These constituents, the process and the heat treatment needed to optimize magnetic properties produces hard (Rc45) and brittle parts that are best shaped or finished by abrasive grinding.

4, Sintered Alnico magnet, which are also alumium-nickel-cobalt iron alloys, is usually restricted to smaller sizes. it has slightly lower magnetic properties, but better mechanical strength than cast alnico magnet.

5, Sintered Alnico magnet is widely used in all kinds of sensors, meters, controller speedometer and other applications.

6, Sintered alnico magnets have slightly lower magnetic properties, however they have excellent mechanical properties.

7, Alnico magnets are excellent choices for applications involving vibration and shock as they have good resistance to demagnetization.

Characteristics:
Suitable for small volume magnets with complex shape
Compact crystal, high intensity
Regular shape, precision size
Even elements, stable performance
Suitable for compound magnet
Excellent temperature stability (temp. coefficient of Br is the smallest among all of the other permanent magnets.)

Application:
Inner magnetic voltmeter/ammeter, electronic type power energy measuring instrument, avometer, flow meter
A wide range of magnetic sensor, polarized relay, temperature and pressure controller
Buzzer of mobile phone, hearing aids, mini speaker
Lighter of automobile, odometer of automobile and motorcycle, permanent magnet motor, absorptive appliance
Widely applied in high stability fields, such as aviation, spaceflight and military technology.
