About Magnets

Encased Alnico Magnets with Threaded Hole

Alnico magnets resist temperatures up to 420° F.

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 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.
