Samarium cobalt magnets, also known as samarium cobalt magnets, are an alloy composed of two basic elements: samarium and cobalt. SmCo magnets are permanent and rare earth magnets available in a varie...
As the name suggests, NdFeB powerful magnets are mainly made of three materials: neodymium, iron, and boron. Of course, there will be other element materials. After all, the ingredients of different p...
Ferrite magnets are permanent magnets mainly made of SrO or BaO and Fe2O3. Compared to other permanent magnets, ferrite magnets are hard and brittle, with lower magnetic energy. However, it is not eas...
The circular coin shaped neodymium magnet with different diameter and thickness are known as neodymium disc magnet or NdFeB or rare earth disc magnets .Neodymium (also known as "NdFeB", "NIB" or "Neo") disc magnets have far stronger magnetism than all other round permanent magnet, and they are the most powerful disc magnets today. Because neodymium disc magnets have powerful magnetic strength, moderate price and can perform well at ambient temperature, they are the most important magnet components in industrial production.Generally,one circular plane of the industrial neodymium(NdFeB) disc magnet is the north pole and the other circular plane is the South Pole,that is axially magnetized neodymium disc magnets. All our NdFeB disc magnets are provided as axially magnetized,unless otherwise specified.

Neodymium (NdFeB) disc magnet are flat&round magnet and usually axially magnetized. Radially or diametrically magnetized neodymium disc magnets are custom neodymium magnets. Diametrically magnetized neodymium disc magnets are only produced according to customer's order.
The magnetic properties of neodymium disc magnets range from N30 to N52. N52 is the highest grade available for neodymium magnets. The size of neodymium disc magnets range from 1mm tiny neodymium disc magnet to 200mm super large neodymium disc magnets.

Neodymium disc magnets are suitable for all types of applications due to their small size and significant magnetic force. You will find that neodymium disc magnets are used in processes and model making, trade exhibition projects, high-performance motors, medical equipment, audio components, scientific research projects, etc.
Make the neodymium disc magnet thicker.
Enlarge the diameter of the neodymium disc magnets.
By using higher magnet grades (such as N52 instead of N30).
By using any combination on the surface.
Please note that the force required to pull the magnet apart is usually 5 times that required to slide the magnet, so you can separate the strong neodymium disc magnets by sliding.
Standard tolerances for neodymium disc magnets with small and middle size are +/- 0.05mm on both diameter and thickness dimensions.
The round and disc shaped neodymium magnets are made by sintering and cutting,the long rod magnets must be sintered first, then machine smaller&thin round neodymium disc magnets by cutting.
Common surface treatment options for rare earth neodymium disc magnet include galvanized, nickel plated (Ni-Cu-Ni) coating.
The strongest & most powerful disc magnets should be made of rare earth magnetic material, neodymium disc magnets are the strongest & most powerful disc shaped magnets in the world.
