1. 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.    
 

2.CUSTOM ALNICO MAGNET SHAPES

Alnico Magnets can customize any magnet shape. We work with you to personalize your magnets for your application. Common magnet shapes include:
  • Rods
  • Bars
  • Assemblies
  • Horseshoe
  • C-shaped
  • Cynlinders
  • Rings
  • Channels
3. Available Size of alnico  magnet rings
Ring Out Diameter(mm) Inner Diameter(mm) Thickness(mm)
Maximum 200 150 120
Minimum 12 4 3

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.
