Sintered alnico magnet:
Compact crystal, high intensity
Regular shape, precision size
Even elements, stable performance
Suitable for compound magnet
Excellent temperature stability
  • DunBen
Product Description

Sintered Alnico magnets are manufactured with powder metallurgical technique, which utilizes high temperature sintering in a controlled atmo sphere to produce near net shape parts. Sizes may range from as small as 0.1g up to 150g.

Common Characteristics of Alnico magnets

  1. Very temperature stable, great for high heat applications 
2. Wi de 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 normal type:

Speakers, Telephones, Mobile Phones 
Odometers, Electric Meters, Water Meters
