Customized Industrial / Electronic Rare Earth Sintered NdFeB Magnet Blocks - Product

Other Specification :  Customized Strong Permanent Sintered NdFeB Magnet With Ni Coating Quick Detail Composite: Rare Earth Magnet Material Shape: Block, Ring, Disc, Cylinder, Or Customized Application: Industrial And Electronic Magnet Grade: N35 N52 Surface Coated: Ni, Zn, NiCuNi Description Sintered NdFeB Magnets Are Produced By Powder Metallurgical Process. NdFe14B Is The Main Element In Neodymium And Gives Neodymium Strong Magnetic Power. In Fact Its Maximum RH Is More Than Ten Times That Of Ferrite. Neodymium Has Good Machinability Properties And Can Work Well At Temperatures Up To 200 Degrees Celsius. Since Sintered Neodymium Easily Rusts, Usually Coated With Such Metals As Zn, Ni, NiCuNi, Au, Sn, Gold Or Epoxy. Application They Are Widely Used In Motors, Speaker, Sensors, Toys, Electronic Products Specification - - - - Grade | Br (mT) | BHc (KA/m) | JHc (KA/m) | BHmax (MGOe) | Density (g/cm3) | Br.Temp.Coefficient (%/) | Working Temp.() | N35 | 1170-1210 | 868 | 955 | 33-36 | 7.4-7.6 | -0.12 | 80 | N38 | 1210-1250 | 899 | 955 | 36-37 | 7.4-7.6 | -0.12 | 80 | N40 | 1250-1280 | 923 | 955 | 38-41 | 7.4-7.6 | -0.12 | 80 | N42 | 1280-1320 | 923 | 955 | 40-43 | 7.4-7.6 | -0.12 | 80 | N45 | 1320-1380 | 876 | 955 | 43-46 | 7.4-7.6 | -0.12 | 80 | N48 | 1370-1420 | 836 | 876 | 46-49 | 7.4-7.6 | -0.12 | 80 | N50 | 1400-1450 | 836 | 876 | 47-51 | 7.4-7.6 | -0.12 | 80 | N52 | 1440-1480 | 836 | 876 | 49-52 | 7.4-7.6 | -0.12 | 80 | - - - - Advantage Strong Magnetic Power Good Machinability Property
