High Precision Super Strong Cylinder Shape Round Rod Sintered AlNiCo Magnet for Meters and Sensors

Sintered AlNiCo Magnets
1.High intensity ans strong anticorrosion
2.Stable magnetic performance
3.Highest usage reach 500'C

Quantity:
sintered alnico magnet for meters and sensors
Sintered alnico is made from a powdered mixture of ingredients that are pressed into a die under tons of pressure, sintered in a hydrogen atmosphere and then cooled either within a magnetic field or without .
 

Feature of Alnico magnets

 1. Very temperature stable, great for high heat applications 
2. Wide range of working temperatures, up to 550ºC
3. May be ground to size 
4. Does not lend itself to conventional machining (hard and brittle) 
5. High residual induction and energy product compared to ceramic material 
6. Low coercive force compared to ceramic and rare earth materials (more subject to demagnetization) 

Application for Sintered Alnico:
Speakers, Telephones, Mobile Phones 
Odometers, Electric Meters, Water Meters
Motors
Switches
Adhesives
Sensors
