About Magnets

Encased Neodymium Magnets with Threaded Hole

A metal case protects the magnetic material.

Nonmarring Encased Neodymium
Magnets with Threaded Hole

A rubber cover protects the mounting surface as well as the magnet.

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 Neodymium Magnets with Unthreaded Hole

A metal case protects the magnetic material.

Encased Neodymium Magnets with Polished Cover

A smooth metal cover gives these magnets a finished appearance.

Nonmarring Encased Neodymium
Magnets with Unthreaded Hole

A rubber cover protects the mounting surface as well as the magnet.

Encased Alnico Magnets with Threaded Hole

Alnico magnets resist temperatures up to 420° 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.
