1. AlNiCo magnet  
AlNiCo pickup magnet is hard and brittle. Machining or drilling cannot therefore be accomplished by ordinary methods. Holes are usually cored in at the foundry, and magnets are cast close to final size and then finish machined to closer tolerances.    
 
 
2.Alnico MagnetManufacturing Methods
AlNiCo magnets are manufactured through either casting or sintering processes.  
Cast magnets are manufactured by pouring a molten metal alloy into a mold and then further processing it through various heat-treat cycles.   

 
Sintered magnets are manufactured by compacting fine AlNiCo powder in a press, and then sintering the compacted powder into a solid magnet.

5.Alnico Magnet Surface Treatments

The corrosion resistance of AlNiCo is considered excellent , and no surface treatments are required. However, AlNiCo magnets are easily plated for cosmetic reasons if required.

6.AlNiCo Magnet appliaction

1) Inner magnetic voltmeter/ammeter, measuring instrument, avometer, flow meter.
2) Magnetic sensors, polarized relay, terperature and pressure controller.
3) Buzzer of mobile phone, hearing aids, mini speaker
4) Lighter of automobile, odometer of automobile and motorcycle, permanent motor, adsorptive appliance
5) Widely applied in high stability field as aviation, space flight and military technologhy
In addition, due to the good corrosion resistance characteristic, non-coating is need for surface protection.
