The advantages of neodymium magnet
Jun 21 , 2018
Sintered neodymium magnet are based on the inter-metallic Nd2Fe14B which has a very high Br and Hcj.
High energy density makes neodymium magnet widely used in the modern industry and electronic applications,which makes instruments, generators,magnetic separators and other products become more smaller,lower weight and thinner.
The advantages of neodymiuc are high cost/performance ratio and good mechanical properties.and the temperature resistance from 80℃ to 220℃. Since NdFeB magnet is easily oxidized,we have to improve its chemical composition and do surface treatment to achieve actual applications.
The process of sintered neodymium magnet is powder metallurgy,the smelted alloy powders are pressed into mould in the magnetic fields,the compression block was sintered into densified products.We usually do thermal effect processing in order to promote the Hcj of the magnets
