We are supplier of White mark NDFEB ARC MAGNET,or call Neodymium block magnet, block sintered NdFeB Magnet, which can be used as fan generator magnets .

1.NdFeB magnet is The strongest power magnets in all of the permanent magnets. Which can be made in different shape, such as Block sintered NdFeB magnet, Disc sintered NdFeB magnet, etc.

2.Material:Sintered Neodymium-Iron-Boron;

3. The material Grade including: N35 to N52;N35M to N50M;N35H to N48H;N35SH to N45SH;N30UH to N40UH,N30EH to N38EH.Also we can suggest the grade according to where the magnets will be used according to our customer's request.

4. Advanced techniques: Utilizes new Sintered NdFeB magnet techniques and equipment such as strip casting, HDDR technology in our factory to allow us to make high performance NdFeB over N52 possible.

5. The Excellent strength value: the highest (BH)max reaches up to 51MGOe.

6. The Extremely Resistance to demagnetization with Hci,the intrinsic coercive force is over 30000Oe.Neodymium magnet loss -0.09~-0.13% on Br/°C;

7. The moderate temperature stability, their working stability is under 80  degree centigrade for low Hci for NdFeB magnet and above 200 degree centigrade for high Hci NdFeB magnet.

8.Various shapes and sizes or according to customers' requirement; Also we can design the size for our customer's request.

9.Effective Surface treatment to prevent corrosion, such Nickel coating(Ni-Cu-Ni coating);Zinc coating, gold coating, silver coating, tin(Sn) coating, epoxy coating, chemical coating, parylene coating, and so on;

10.Widely used in different application, such as sensors, Motor,rotors, wind turbines/wind generators, loudspeakers, magnetic hooks, magnetic holder, filters automobiles and so on;

11.The quality control: we have our large and expert quality control department and we ensure the magnets ( block sintered NdFeB Magnet,block Neodymium Magnet) from our factory are in high quality.

12.We will provide our customers the test report and BH curves for each item magnets, and also we can do the PCT test ,salt spray test report, aging test report and provide the test report and so on according to our customer's request.

 Neodymium arc-segment magnets is one special shape of Rare earth magnets and permanent magnets. It is always manufactured via Wire Cutting and grinding etc. Regular Arc magnets or Segment magnets have the following important factors such as, Outer Diameter Or Outer Radius, Inner Diameter or Inner Radius, Degree of Angle, Thickness, Length, Round Edge etc 

Generally speaking, Arc Magnets are all made as Customer Design and as Special requirement. 
Our factory produce and manufacture magnets according to customer's design on shape, dimension, grades, coatings etc. 
To offer you our Arc magnets price, please offer the following details: 
Magnets grade: From N35 To N50, from N Series to UH Series. 
Magnets drawing with size and shape and different side view. 
Magnetism direction: Mostly magnetized via diameter, if special magnetism direction, please show on the drawing in advance. 
Magnets coating: Nickel, Zn, Black Epoxy, AG, Au etc. 
Quantities: More mass order quantities. More Lower the prices. Original factory.
