About the Product

Neodymium disc magnets are a compact, high-energy format used for sensor prototypes, closures, and robotic fixtures. The round footprint seats cleanly in counterbores and adhesive pockets, with consistent thickness tolerance for reliable stack-ups. Standard axial magnetization provides predictable pull to steel. During test-fit, use the Pull Force Calculator to estimate holding force and select coatings appropriate to the environment; consult material data when evaluating grade and thermal behavior.

D1077 is the perfect size for what I needed to use it for.

This is a strong magnet for its size.

For the purpose we were shooting for they are nowhere near strong enough. Doesnt affect the 34” Gongs pitch. Would need a lot more mass for eadh magnet. I will keep them for other projects!

After spending the past few years (hit and miss) sourcing neodymium magnets from other resources on the web. I happened upon Super Magnet Man (supermagnetman.com). I have placed two orders so far and have been extremely satisfied with both. I am a magician. I spend a significant amount of time determining the specifications for my builds and on my two most recent projects I was able to come here and find a magnet fitting the exact dimensions required.
