Product Name: China Magnet Manufacturer Strong Block NdFeB Magnet Model NO.: Block NdFeB Magnet Coating: Nickel Shape: Block Application: Industrial Magnet Type: Permanent Composition: NdFeB Magnet Trademark: Yuxiang Transport Package: Neutral Paper Carton Packing Specification: ROHS, SGS, CE Origin: Fujian, China (Mainland) HS Code: 850511900 Product Description Block NdFeB MagnetGeneral DescriptionNeodymium block magnets (ND-Fe-B) are composed of neodymium, iron, boron and afew transition metals. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discFeatures:1. Attributes of Neodymium2. Very high resistance to demagnetization3. High energy for size4. Good in ambient temperature5. Moderately priced6. Material is corrosive and should be coated for long term maximum energy output7. Low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically.Applications:Magnetic separators, linear actuators, microphone assemblies, servo motors, DC motors (automotive starters), computer rigid disc drives, printers and speakers...ParameterunitStandard DataCurie Temperature(Tc)ºC310-380Maximum Operating Temperature(Tw)ºC80-200HardnessHv620Electrical ResistivityΩ.CM1.8X10-4 ~2.0x10-4Density(D)g/cm37.5~7.65Recoil Permeabilityµ rec1.05Magnetization Field Strength(Hs)KOe> 30KA/m> 2400Bending StrengthMpa295~345Temp.
