Price: [price_with_discount] modname=ckeditor Description: Shape: disc Size: diameter 3mm x thickness 3mm Tolerance: + -0-0.5mm Material: neodymium magnet Authentication: RoHS pass Grade: N42 Magnetization: the pole at the axial magnetization / flat ends. Maximum working temperature: 80 degree C / 176 degree F Neodymium (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. Neodymium block magnet was made of NdFeB, have strong magnetic performances and appearance does not rust, usually placed in room temperature, the maximum operating temperature is 80 ° C ,and it never will demagnetization. Applications Acoustic field: the speaker, receiver, microphone, alarm, stage audio, car audio and so on….
