Magnet-Backed Standoffs
The magnetic end of these standoffs makes it easy to temporarily mount or reposition components on magnetic surfaces. They’re also good for tight spaces where it’s difficult to drill a hole. All standoffs are made of metal, which concentrates and focuses the strength of the magnet inside, so they maintain their strength even on thin magnetic materials. This metal also protects the magnet from damage.
Standoffs with an alnico magnet withstand temperatures up to 840° F, more than four times that of standoffs with a neodymium magnet. However, they’re not as strong as standoffs with a neodymium or other rare earth magnets.

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.
