Neodymium Disc - 20mm x 3mm  N42 (Epoxy)

Magnetic Product Description:

This rare earth disc has a diameter of 20mm and a height of 3mm. It has a magnetic flux reading of 1810 Gauss and a pull force of 4.3kg. It is identified by the AMF magnet part number 20018A.


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.

Review on 20mm x 3mm epoxy magnets

Very happy with the fast delivery and strength of these magnets. I used them for a fashion project recently and were the perfect strength and size. I particularly liked that these were black in colour

(better suited my garment) as opposed to the standard silver colour. Highly recommend these magnets, especially if being used for a fashion-garment related project!

Thankyou!

Just perfect for my application

I needed a way to support a few flags up against a wall, the wall fortunately had a steel cross-member that makes up the lintel on a few doors, solution use magnets, needed strong ones to ensure nothing moves, these were perfect.
