About Magnets

Uncoated Neodymium Magnets

Cover these unfinished magnets with your choice of coating to prevent corrosion. Made of neodymium, these rare earth magnets are the strongest for their size.

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.
