Ceramic Channel-Type Magnets are made in a variety of simple and complicated shapes and sizes. Ceramic Holding Assemblies provide a strong magnetic field. The ceramic magnet material possesses high coercive force and resists demagnetization from heat, vibration, and electrical fields. Most of our ceramic assemblies are permanently embedded in epoxy plastic. They are typically more economical than Alnico assemblies and can be used in temperatures up to 180°F. Temperatures higher than 180°F can cause the standard epoxy that holds the magnet material to fail.
Alnico Channel-Type Magnets are made in a variety of simple and complicated shapes and sizes. The alnico magnet material derives its magnetic properties and name from the elements aluminum, nickel, and cobalt. Alnico magnets have the widest range of temperature stability of any standard magnetic material (up to 1000°F) and possess excellent corrosion resistance. Cast alnico magnets may be manufactured in complex shapes, such as horseshoes, and are suitable for a wide range of applications. Alnico channel magnets work by channeling great holding strength onto one large surface, placing a strong alnico magnet into a plated steel channel in order to concentrate magnetic power and provide the magnet itself with protection and a sturdy fixture for them to be positioned in. Channel magnets are durable, easy to use, and powerful.
