Ndfeb Ring Magnet
1. Excellent strengthvalue: the highest (BH)max reaches up to 51MGOe.
2.advantage: Extremely Resistance to demagnetization with Hci,theintrinsic coercive force is over 30000Oe.
3. Moderate temperaturestablity: under 80°C for low Hci NdFeB magnet and above 200 °C for highHci NdFeB magnet.
4. Coating: Effective Surface treatment toprevent corrosion, such as Nickel, Ni-Cu-Ni co, Zinc, gold, siliver, tin(Sn),epoxy, chemical, parylene, etc.
5.Shapes and sizesof NdFeB magnet ring:various according to clients'request
6. Application: Sensors, Motors, Rotors, Windturbines/wind generators, Loudspeakers, Magnetic hooks & holder, Filters,Automobiles, etc
