Sintered neodymium magnet is the strongest magnetic material commercially available today. It is largely made of alloy of neodymium, iron and boron, and the chemical formula is Nd2Fe14B. Sintered NdFeB neodymium magnet exhibits high magnetic energy product in small size with high coercive forces. Examples of applications include permanent magnet motors, loudspeakers, magnetic separators, wind power generators, computer hard drive, and MRI devices. For more technical information of our sintered neodymium magnet, please refer to the sections of Technological Advantages, Demagnetization Curve, Grades, Magnetic Properties, Physical Properties, Magnetic Parameters, Surface Treatment, Magnetization Orientations. Technological Advantages High Coercive Force Highest Intrinsic coercive force Hcj≥35kOe High Consistency CPK of Remanence (Br) and Intrinsic coercive force (Hcj)>1.67 Low Reversible Temperature Coefficient αBr=-0.08%/℃, βHcj=-0.4%/℃ Low Weight Loss 130℃, humidity 100%, vapor pressure 2.7bar, 20days, average weight loss<2mg/cm2 Demagnetization Curves of Sintered Neodymium Magnet Grades The Grade of a magnet generally indicates how "strong" a magnet material is, which is measured by the Maximum Energy Product. The energy product is commonly specified in units of Gauss Oersted. The higher the grade the "stronger" the magnet. The grade also tells the temperature rating of a magnet material. Neodymium magnets have different heat tolerances which determine their maximum working temperature. As the heat tolerance increases the maximum available flux density decreases. Magnetic Properties of Sintered Neodymium Magnet Notes: 1. The above-mentioned data of magnetic parameters and physical properties are given at room temperature(20℃±2). 2. The maximum service temperature of magnet is changeable due to the ratio of length and diameter, coating and environmental factors Physical Properties Magnetic Parameters Surface Treatment As Neodymium magnet is prone to corrosion, it is usually preferable for the magnet to be coated for protection. Among a variety of options for coatings, nickel and nickel-copper-nickel are the most commonly used, making the magnet more corrosion resistant and durable.
