We supply various sizes of round disk neodymium magnets for users and distributors, the size of 20x3mm is very popular in the round disc neodymium magnets market.
The magnetic energy product range of 33-53 MGOe make the round disc magnet 20x3mm powerful and surpasses any other magnetic material.
Thin neodymium magnets of 20x3mm should be properly operated and used,neodymium-iron-boron is fragile.
20x3mm rare earth neodymium disc magnets are usually plated with nickel or epoxy for the need of resisting corrosion.
