Product Introduction And Advantages

The sintered NdFeB permanent magnet is made by powder metallurgy, and its chemical combination is Nd₂Fe₁₄B. It is the highest magnetic material at present. Its advantages are anti-demagnetization and cost-effectiveness. Its disadvantages are relatively strong temperature dependence and relatively weak corrosion resistance. But after proper coating or electroplating, plus the use of products with different coercivity in different use environments, NdFeB can basically meet the requirements of different customers.

The tile-shaped motor magnet must fit seamlessly with the entire motor or generator, including the laminations, the required number of poles, wire size and surrounding components. Choosing the right permanent magnet will ensure the most efficient operation of the motor or pump and provide the required torque, RPM and output.

Arc-shaped permanent magnets are generally used in high-performance products, and are also called segmented magnets.

It is usually used in motors, generators, pipelines, etc.

We can also manufacture special arc magnets, crescent magnets and arc magnets with countersinks. Most of the magnets we produce are customized by customers. If you have any requirements, you can send us an inquiry and tell us the size, tolerance, surface treatment, performance, quantity, magnetization direction, and application of the magnets we need. Will send you our quotation. If you are not sure what kind of magnets your products need to be equipped with, you can also ask us. We will listen to your needs carefully and recommend suitable magnets for you to choose according to your specific needs. We sincerely welcome you to get in touch with us.

Surface Treatment

Sintered NdFeB permanent magnet material is a powder metallurgical material with strong chemical activity, its characteristics are hard and brittle, and it is easy to be oxidized and corroded. Based on this feature, the most effective method currently adopted is to coat the surface. The usual methods are blue and white zinc plating, color zinc, nickel copper nickel, chemical nickel, epoxy resin, phosphating and so on.

We can also perform surface treatments such as silver plating, gold plating, Everlube, etc. according to your requirements.
