Ring shape High Temperature Alnico Magnet , Aluminum Nickel Cobalt Magnet

Material:Cast alnico magnet
Grade: alnico2-alnico9
Size:Typical dimensions and customized
Magnetism direction: Customzied Specific Requirements
Tolerances: Cast surface +/-0.38-+/-0.5mm
Ground surface +/-0.01-+/-0.1mm
Application: Speaker Magnet, Industrial Magnet, Jewelry Magnet, Motor Magnet
Certification ISO/TS16949:2009, ROHS,SGS

Quantity:
AlNiCo magnet  
AlNiCo 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.    
Characteristics
1.Compact crystal, high intensity
2.good chemistry stability, strong anti-corrosion
3.Even elements, excellent and magnetic performance
4.Excellent temperature stability
5.Highest usage temperature reach 550°C


Size Specifications:

Applications:

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.
