Alnico Disc Magnets
Alnico magnets aren't as strong as rare earth magnets, but they withstand the highest temperatures.
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.

Alnico Magnets with Unthreaded Hole
Alnico magnets aren't as strong as rare earth magnets, but they withstand the highest temperatures. Slide onto a rod or use a bolt or screw to install.
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 Alnico Magnets with Threaded Hole
A steel case concentrates and focuses the magnetic field. It also protects the magnetic material. Alnico magnets aren't as strong as rare earth magnets, but they withstand higher temperatures.
A keeper covers the poles to preserve the strength of the magnet and protect it from attracting metal during storage.
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.
