About Magnets

A steel case concentrates and focuses the magnetic field. It also protects the magnetic material.

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.

Flexible Magnets

These flexible magnets are made of corrosion-resistant ceramic and bonded with rubber for flexibility. Use scissors to cut them into custom shapes and sizes.

Rubber adhesive adheres quickly and works especially well on plastics.

Acrylic adhesive is more water- and chemical-resistant than rubber adhesive.
