China sintered Alnico factory manufacturers Block Bonded Magnet

N42 Sintered Ndfeb neodymium block magnets 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 called Ndfeb magnet, which 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, and has strong magnetic performances and appearance does not rust. The magnets are 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. Electronics:  permanent magnetic…
