Description
Epoxy plated disc neodymium round magnet are strong rare earth magnets that has an additional epoxy coating on top of the standard nickel-copper-nickel to provide better resistant to water and rust. Black epoxy plated neodymium is much stronger than the weaker ferrite/ceramic magnets, the black colour plating makes it look very similar to the regular black ferrite magnet. Each piece is 20mm diameter with a thickness of 3mm overall measurement inclusive of the epoxy coating.
Caution: Do not drop these magnets on hard surface or let 2pcs smash together, it will break on impact!
These are the characteristic of neodymium magnets.
The additional epoxy coating on these magnets offer better protection against water, rain or humid which will cause normal nickel-copper-nickel plated neodymium magnets to rust in a few weeks.
While epoxy coating does offer better water resistance and endure wet environment much better, the coating may still be compromised if submerged or subjected to harsh conditions over prolong period of time.
