N52 Neodymium Large Ring Magnets
Neodymium magnet, the third generation of the rare-earth permanent magnet, is the most powerful and advanced permanent magnet today. Neodymium is named as"Magnet King" for its high remanence, high energy. Moreover, it has the high performance and high-cost ration, because of the rich rare earth resources in China and the ever-changing production process and technological progress. It can be easily formed into various sizes and different shapes, such as segment, ring, block, etc.

We accept customized services:
1) Shape and Dimension Requirements;
2) Material and coating requirements;
3) Processing according to design drawings;
4)Requirements for Magnetization Direction;
5) Magnet Grade Requirements;
6) Surface treatment requirements (plating requirements)


Neodymium magnets are a composition of mostly Neodymium, Iron and Boron. If left exposed to the elements, the iron in the magnet will rust. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated. There are a variety of options for coatings, but nickel is the most common and usually preferred. Our nickel plated magnets are actually triple plated with layers of nickel, copper, and nickel again. This triple coating makes our magnets much more durable than the more common single nickel plated magnets. Some other options for coating are zinc, tin, copper, epoxy, silver and gold. Our gold plated magnets are actually quadruple plated with nickel, copper, nickel and a top coating of gold.

Common direction of magnetization bellow:
1> Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametrically.
2> Rectangle shape magnets can be magnetized through Thickness, Length or Width.
3> Arc shape magnets can be magnetized Diametrically, through Width or Thickness.

Special direction of magnetization can be customized as required.

1). Electronics – Sensors, hard disk drives, sophisticated switches, electro-mechanical devices etc.;
2). Auto Industry – DC motors (hybrid and electric), small high-performance motors, power steering;
3). Medical – MRI equipment and scanners;
4). Clean Tech Energy – Water flow enhancement, wind turbines;
5). Magnetic Separators – Used for recycling, food and liquids QC, waste removal;
6). Magnetic Bearing – Used for highly sensitive and delicate procedures in various heavy industries.
