    About Magnets
    industrial info icon

    Choose a magnet with the right strength, material, and temperature resistance for your application.

    Ceramic Disc Magnets

    Our most economical magnets cut costs, not reliability. They stay strong in temperatures up to 400° F and resist some corrosion. They’re also nonconductive to prevent short circuits in DC motors, transformers, and speakers. However, they are not as strong as rare earth magnets.
    Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron surfaces. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.
