Custom Industrial Rare Earth Permanent Magnets Bulk For Sale

Understanding permanent magnets/rare earth magnets and how their application can play into the innovative devices of today's markets is the foundation of our business. As one of the diametrically magnetized ring magnets suppliers, Leyuan Group's long history of magnetic expertise allows us to partner with you to deliver the best permanent magnet product, such as steel permanent magnet, strong permanent magnet, tiny permanent magnets, and suspended permanent magnet for your needs.

As one of the leading permanent magnet suppliers and rare earth magnet suppliers, Leyuan ship different types of permanent magnets in magnetized or non-magnetized forms according to our customers requests. Permanent magnets have high coercive forces and, therefore, keep their magnetic field stably under a proper application after they are magnetized.

The term permanent magnet comes from the ability of the magnet to hold an induced magnetic charge after it is removed from the magnetizing device.

When to choose permanent magnets for your application?

If you need help determining the best choice for your application, whether it be Neodymium Iron Boron Magnets, AlNiCo Magnets or Samarium Cobalt Magnets, we would be glad to assist you. Simply give us a call on 86-574-82819201 or email us at

Types Of Custom Powerful Rare Earth Permanent Magnets Wholesale

Neodymium Magnets
Neodymium Magnets

Sintered NdFeB magnets are produced in a powder metallurgical process and have the highest magnetic strength. They are widely used in MRI, VCM, motor, separator, lifting, sensor and loudspeaker applications. Leyuan has a production capability of over 100 tons per month. We also produce low temperature-coefficient materials which can work well under high temperatures.

Samarium Cobalt
Samarium Cobalt

Our Sintered Samarium Cobalt Magnet is characterized by high magnetic properties, outstanding thermal stability and excellent corrosion resistance ability. They are the ideal material in applications like servo-motors, pump couplings, and sensors, particularly where the magnet is required to work at high temperatures and/or in a corrosive environment. The temperature range for this magnet type is 250℃ to 350℃.

FAQs Of LEYUAN Large Rare Earth Permanent Magnets For Sale

How Long Do Permanent Magnets Last?

If the external environment does not change, it may exist permanently. However, if high temperatures, strong vibrations, positive and negative magnetic field, oxidation and other actions are applied, the permanent magnet will lose its magnetism quickly.

Are Thicker Magnets Stronger?

Yes, but not in direct proportion. As the thickness increases, the magnetic force increases slowly.

What Are The Uses Of Permanent Magnet?

Magnets are widely used in many applications including loudspeakers, motors, magnetic filters, magnetic pickup, magnetic drives, magnetic suspension, etc.

Can A Magnet That Has Lost Its Strength Be Re-magnetized?

Yes! Just put the magnet into a strong magnetic field to get its strength again. Equipment named magnetizers can provide a strong magnetic field.

Which Shape Of Magnets Is The Strongest?

The size of the magnetic force has no clear relationship with the shape but has a close relationship with the volume of the magnet. Of course, cylindrical or square-shaped magnets are the easiest to make.
