Alnico Holding Magnets

Features

  • Standard and Custom Magnet sizes
  • Technical Application Assistance from Prototype to Production
  • Precision Cutting, Grinding, Fabrication and Assembly to your specifications.

Benefits

  • Expertise in applying over 100 million magnets
  • High holding strength allows holding of heavier parts with greater stability.

Applications with temperatures up to 900°F can be achieved without damage to Alnico magnetic material or Magnet Assembly.

Alnico Pot Magnet Holding Assemblies

Alnico Pot Holding Magnets are assembled with non-magnetic sleeves between the magnet and the “pot”. The absence of epoxy binder allows for high temperatures and chemical stripping applications.

Pot magnets for applications that require greater holding values are available with Rare Earth magnetic material – Neodymium Iron Boron (NdFeB) for up to 180°F, Samarium Cobalt Magnet (SmCo) for up to 575°F.

Alnico Sleeve Magnet Holding Assemblies

The Storch brass-sleeved, Alnico round magnets are externally insulated permanent magnets. This series has been designed to supply magnetic holding in inaccessible areas, steel fixtures, tools, dies, and other steel components.  Sleeve magnets can be installed into blind holes in ferrous metal to provide maximum holding value.
