About Magnets

Uncoated Neodymium Magnets

Cover these unfinished magnets with your choice of coating to prevent corrosion.

Alnico Bar Magnets

Alnico Disc Magnets

Alnico Horseshoe Magnets

Alnico Button Magnets

Alnico Rotor Magnets

These magnets have a central hole for mounting on shafts. Use them in motors and turbine generators.

Alnico U-Channel Magnets

Ceramic Magnets

Ceramic magnets resist demagnetization better than other magnets and are an economical choice. They resist temperatures up to 400° F.

Samarium-Cobalt Magnets

Strong and compact, these rare earth magnets resist temperatures up to 570° F.

Ceramic Magnets with Unthreaded Hole

Ceramic magnets resist demagnetization better than other magnets and are an economical choice. They resist temperatures up to 400° F.

Alnico Magnets with Unthreaded Hole

Alnico magnets aren't as strong as rare earth magnets, but they withstand the highest temperatures—up to 970° F.

Encased Magnets

Encased Ceramic Magnets with Unthreaded Hole

Ceramic magnets resist demagnetization better than other magnets and are an economical choice. They resist temperatures up to 480° F.

Encased Ceramic Magnets with Threaded Hole

These ceramic magnets resist demagnetization better than other magnets, and have a metal case to protect the magnetic material. They resist temperatures up to 175° or 245° F.

Encased Alnico Magnets with Threaded Hole

Alnico magnets resist temperatures up to 420° F.

Encased Ceramic Magnets

A case protects the magnetic material.

Nonmarring Encased Ceramic Magnets

A plastic case protects the mounting surface as well as the magnet.

Press-Fit Encased Magnets

Press these magnets into a drilled hole so they are flush against the surface.

Conformable Magnets for Irregular Surfaces

Stretch these magnetic strips over corners and irregular surfaces.

Machinable Magnets

These magnets are bonded with epoxy resin, so they can be machined with carbide tooling.

Machinable Magnets with Unthreaded Hole

Slide these magnets onto a rod or install with a bolt. They are bonded with epoxy resin, so they can be machined with carbide tooling.

Building and Machinery Hardware

Magnetic Latches

Often used on audio/visual cabinets, magnetic force keeps your doors closed.

Magnetic Wall-Mount Door Holders

A magnet holds the door open; pull on the door to release.

Magnetic Floor-Mount Door Holders

A magnet holds the door open; pull on the door to release.

Multi-Compartment Belt Pouches

Slip these pouches onto your belt to keep several tools within reach.

Magnetic Contact Alarm Switches
