Neodymium magnet is also called” NdFeB magnet, or rare earth magnets”, which is based on Nd2Fe14B. The main components are rare earth elements Neodymium (Nd), iron (Fe), and boron (B). Its main raw material is rare earth metal neodymium about 30%, metallic element iron about 65%, non-metallic element boron about 1% and other elements.
-What are magnetic properties?
-There are different grades based on the maximum energy product and these are related to magnetic flux output, high value means strong magnets. Like NdFeB magnet, it has international classification chart, which mentioned exact parameters for Remanence(Br), Coercivity(Hcj),Maximum Energy product(BHmax) and working temperature(C°) etc. The ordinary grades of sintered NdFeB magnets have: N33-N52,N35M-N48M,N33H-N46H,N33SH-N44SH,N30UH-N38UH,N30EH-N35EH etc. All these magnetic grades can be tested by special testing machines and compared with standard international property chart to tell whether the Neodymium magnets were made in right quality or not, usually a standard testing report about magnetic property test will be provided before shipment for customer.
-Application: electric motors, speakers, electronics, medical equipment, wind turbines, aerospace, toys, magnetic tools and other fields.
-Main Process flow: raw material – smelting ingot/spinning belt – powder making – profiling – sintering – grinding – cutting – electroplating – finished product.
-Main Testing: dimensions Inspection, gauss test, magnetic flux test, magnetic property test, salt spray test, coating thickness test, pulling force test.
