Small Sintered Neodymium Rare Earth Sphere Magnets

NdFeB, the third generation of the rare earth magnetic material, is one of the best cost performance permanent magnetic materials with high coercive force and excellent Br and Bhmax ;which is made of Nd, Fe, B, Dy, Co and other minor elements; Because of good mechanical properties, it can be easily shaped into differents sizes .Therefore, it is widely used in motors, wind energy, Audio products, telecommunications, meters, magnetic resonance product, magnetic levitation product, VCM, MRI, etc.

NdFeB magnet need the surface treatment to protect it from corrosion, coating can be Ni, NICUNI , bright NI, Dark Ni, Chemical NI, Zn , Blue Zn, Color Zn, Gold, Silver, phosphate , Epoxy, NI+ Epoxy, Zn+ Epoxy, parylene, etc. we can do the special coating in according to customers request.

NdFeB magnet's life span is affected by temperature and humidity. we welcome you to contact us for more details.

We are specialized in producing NdFeB Magnet over many years,We guarantee the best price based on the same quality and service. Our finance conditiearon and industrial reputation are excellent.

Testing Center

We are ISO/TS16949:2002 certified and well implement all procedures strictly under control. Problem preventive actions and quality assurance are preoperly combined with special inspection for all procedures from raw material purchasing ,outside cooperating part manufacturing,inside manufacturing to shipping . We also install a complete set of physical and chemical test equipment to make sure that all our products are manufactured and shipped under strictly quality control .

Salt Spray Test :

Mainly test the surface treatment against the corrosion.  Usually the tested samples will be  continuous sprayed 24 hours in the 35℃ temperature to see if there is any rust appearance on the surface. 

Projection Instrument:

Mainly test the magnets with irregular shapes such as arc segments and any other irregular-shaped parts to see if their dimensions meet the customers' requirements or not.  

PCT Instrument:

Mainly test the magnets to prevent against corrosion on the high temperature and high atmospheric pressure . Usually the test condition is 120℃ temperature and 2 atmospheric pressure .

Heat& Humidity Instrument:

Mainly test the magnet to against corrosion on certain temperature and humidity . Usually the test condition is 80℃ temperature and 90%+/-3% humidity

Hysteresgraph:

Mainly test the magnetic characteristics of the magnet, including Residual (Br ), Coercive(Hcb) . Intrinsic  Coercive(Hcj), Max. Energy product(BH max) and any other related magnetic parameters.
