 We can produce top grade neodymium magnet,

like N52,N50M,N48H,N45SH,N42UH,N40EH,35AH (max 250C) magnet. 


We are professional sintered ndfeb magnet manufacturer, we mainly produce high quality sintered ndfeb magnets, with ENERGY PRODUCTS from 33MGOe to 52MGOe, the operating temperature range is up to 250oC. We produce and design the ndfeb magnet as your specification and requirement. 


NdFeB magnet (neodymium magnet) is mainly made from neodymium, iron and boron. With excellent magnetic property, abundant raw material and reasonable prices, NdFeB Magnet is used as an ideal magnet in instruments and meters, mini-motor, magnetic transmission machine, medical apparatus, aviation, electronics and etc. For NdFeB, if left it exposed, the iron in the magnet will rust. 

To protect the magnet from corrosion, 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. Some other options for coating are zinc and epoxy.


Applications of the Neodymium magnets(Ndfeb Magnet)

Voice coil motor of hard disc motor, pick-up of optical disk drive, mobile phones, magnetic resonance image, Hi-Fi system, auto motors, wind-power generators, MRIs, magnetic separators, lifting equipment, spaceflight equipment and new energy products, etc. Especially suitable for the development of high-performance, compact and light products.

NdFeB Permanent Magnets 

The third generation of rare earth-permanent magnetic ND2Fe14B is the strongest performance of permanent magnetic in the contemporary era. Its possess a high potential magnetic properties, can be easy to be cutting and drilling, so as processing of complex shape. Now, permanent magnetic ND2Fe14B are widely used in aeronautics and astronautics, electronic, electromechanical, instrument, medical treatment. Besides, it also have a growing market in non-technical field, such as toy, jewelry and so on. 


Production process: 

Charge mixture--->Smelt--->Powder process--->Forming--->Clotting--->Testing--->Machining--->Electroplate--->Magnetization--->Checkout--->Packing 


Advantages of NdFeB 

1)Possess a first-class position in the permanent magnets' performance. 

2Possess a excellent mechanical properties, thus it can be easily cutting drilling and complex shape processing.

3)Possess a cheap raw materials and abundant storage, which contribute to it tangible benefits prices. 

4)Possess a value of BHmax 5-12 times more than Ferrite magnets, and 3-10 times more than AlNiCo magnets. 

5)Possess a ability of coercive equivalent 5-10 times more than Ferrite magnets, and 5-15 times more than AlNiCo magnets. 

6)Possess a high potential of its performance, for it can absorb the heavy weight which is 640 times to its own. 


Surface treatment: 

1)Plating with metals, such as galvanizing, nickeling, gilding, silvering, etc. 

2)Organic plating, for instance, Epoxy resin coating, nickel + epoxy resin coating. 

3)Temporary: Surface passivation. 

4)Coated black or others.  


Shape of products: Ring shape, round cake, square, trapezoid, spherical, tile. Cylindrical, pentagram, etc. And we can also according to customer's drawings to make any shapes by line cutting and die bed.
