Uses for our rare earth disc magnets

These Neodymium Disc magnets have an Epoxy coating that prevents damage to the magnet and other surfaces it is contact with. Choosing the appropriate coating for your application is a key consideration as magnets are prone to corrosion or magnetic degradation in humid atmospheres. These Epoxy coated disc magnets are a practical choice for outdoor use or locations that are susceptible to moisture. The disc is produced from N42 grade magnetic material and this serves to compensate for the adverse effect of the coating which creates a small gap between the magnet and the steel surface it is applied to.
