Samarium-Cobalt Magnets
Samarium-cobalt offers a balance of strength and temperature resistance. Strong and compact, these rare earth magnets resist corrosion and can handle higher temperatures than other rare earth magnets.
Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

Encased Samarium-Cobalt Magnets
Strong and compact, these rare earth magnets resist corrosion and can handle higher temperatures than other rare earth magnets. A metal case protects the magnetic material.
Magnets with iron and brass cases concentrate and focus the magnetic field.
Knurled magnets are easier to grip than smooth magnets.
Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.
