Neodymium disc magnets with countersunk holes offer strong magnetic hold and easy mounting with screws or bolts. They're used in various industries for closures, fixtures, signage, and more.
Unlike gold, zinc and nickel, an epoxy magnet coating acts as an excellent barrier to salt, ambient air, water or moisture. But it's slightly more expensive than the first three alternatives. Although it is easy to scratch, with a thickness of 15-30 um, it has good adhesion to steel with magnetic glue. Epoxy coatings are mainly used in the Marine, motor, sensor, automotive and consumer goods industries.
The surface treatment of NdFeb magnet is not to improve its performance, and the surface coating of neodymium magnet mainly plays a protective role. No surface coating of NdFeb strong magnets, it is easy to react with oxygen in the air and quickly oxidize, so in order to prevent this from happening, we usually carry out plating treatment. Moreover, the appearance of the strong magnet after electroplating is more beautiful.
Neodymium disc magnet with 3M adhesive, can be easily fixed to non-metallic surfaces with adhesive. Because the adhesive is not resistant to high temperatures, please use it at normal temperatures.
NdFeB magnets, also known as neodymium magnets, are a type of permanent magnet made from an alloy of neodymium, iron, and boron. They are the strongest type of permanent magnet commercially available, offering high magnetic strength and excellent performance in a wide range of applications.
Neodymium(NdFeB) magnets are the strongest type of rare earth magnet commercially available and are manufactured in a wide range of shapes, sizes and grades.
