Alnico magnets are made primarily from aluminum, nickel, cobalt, copper, ironand sometimes titanium.
1) Alnico magnet have high magnetic flux density
2) strong corrosion resistance
3) excellent temperature stability, the maximum working temperature up to60°c.
4) Alnico magnet is widely used in all kinds ofsensors, electronics, instruments, automobile and otherapplications
5) due to the good corrosion resistancecharacteristic, non-caoting is need for surface protection.
6) there are two different manufacturing process foralnico: cast and sintered
