The 20x1.5mm round disc magnets are made of the strongest magnetic material of neodymium,the maximum magnetic energy product is 53 MGOe.
Neodymium-iron-boron must be coated,nickel is the most popular rust resistant coating for round disc neodymium 20x1.5mm
Neodymium magnet is fragile,especially thin disc neodymium magnets,like as 20x1.5mm, it must be properly operated and used.
Good quality,reasonable package,short lead time and cheap price will be available.
