    high quality round hard drive magnet   1.Material: Neodymium-Iron-Boron   2.Size:  5x1mm   3. Magnetic property: From N35 to N52, 35M to 50M, 35H t 48H, 33SH to 45SH, 30UH to 40UH, 30EH to 38EH;we are able to manufacture the full range of Sintered Nd-Fe-B products including the high energy magnets such as N52, 50M, 48H, 45SH, 40UH,38EH,34AH, (BH)max from 33-53MGOe, maximum working temperature up to 230 Degrees Centigrade.    4. Coating: zinc   5. Advantage: a. Chemical Composition: Nd2Fe14B: Neodymium Magnets are hard, brittle and easily corrode; b. Moderate Temperature Stability: Neodymium magnets lose -0.09~-0.13%of Br/°C. Their working stability is under 80°C for low Hcj Neodymium magnets and above 220°C for high Hcj Neodymium magnets; c. Excellet Strength Value: The highest(BH)max reaches up to 51MGOe;   6. Application: sensors, speakers, brushless motor, DC motor, Step motor, wind turbine/wind generator, magntic hooks, magnetic filter, cup magnet, Automobiles, magnetic coupling, magnetic chuch, Permanent Magnetic lift, and so on.     7.  the  physical properties,
