N52 25mm x 5mm Strong Round Disc Magnets Rare Earth Neodymium Magnets

Description:N52 25mm x 5mm Strong Round Disc Magnets Rare Earth Neodymium MagnetNeodymium (chemical symbol Nd) is element 60 on the periodic table. It is a rare earth metal and forms one of the Lanthanides series. When added to Iron (Fe) and Boron (B) (chemical formula Nd14Fe21B) the resultant magnets are the strongest magnets currently available. Neodymium magnets are sometimes known as Neo, Neod or NIB magnets.Neodymium magnets are usually coated Nickel-Copper-Nickel plating to prevent the iron from rusting.Usually placed in room temperature, the maximum operating temperature is 80C , and it never will demagnetization.Specification:Shape: DiscGrade: N52Size: 25mm x 5mmPlating: Ni-Cu-Ni ( Nickel )Material: NdFeBOperating temperature: 80℃Quantity: 1 PieceApplications:Acoustic field: the speaker, receiver, microphone, alarm, stage audio, car audio and so on.Electronics: permanent magnetic actuator vacuum circuit breakers, magnetic relays, meter, meter, sound meter, a reed switch, sensors.Electrical field: VCM, CD / DVD-ROM, generators, motors, servo motors, micro-motors, motors, vibration motors.Machinery and equipment: magnetic separation, magnetic crane, magnetic machinery.Healthcare: MRI scanners, medical equipment, magnetic health products and so on.Other industries: magnetized Wax, pipe descaling, magnetic fixture, automatic mahjong machine, magnetic locks, doors and windows magnetic, magnetic luggage, leather magnetic toys, magnetic tools, gifts and packaging.Tip:1, St
