NdFeB(Neodymium Iron Boron)
1> The third generation of rare earth permanent ndfeb magnet is contemporarily the most performance of the permanent magnet. it can suck up as much as 640 times as its own weight
2> Due to main raw material of NdFeB magnet is very cheap, rare earth neodymium reserves is more ten - 16 times than samarium, so the price is much lower than samarium cobalt magnet.
3> Ndfeb magnet mechanical performance is better than samarium cobalt magnet and alnico magnet , it is more easy to cut and drill , including complex shape processing.
4> The disadvantages of NdFeB magnet is temperature for poor performance . normally, it is for 80 degrees Celsius, after special treatment , the plating highest working temperature can reach 200 degrees Celsius.
5 >Due to the material contains a large number of neodymium and iron, so it is easy to rust ,so, ndfeb magnet must be surface coating processing. it can be nickel (Ni), zinc (Zn), gold (Au), chromium (Cr), Epoxy resin (Epoxy), etc.
6> Ndfeb magnet has been widely used in aerospace, electronics, mechanical and electrical, instrumentation, medical, etc. also, it is being used more and more widely in non-technical fields , such as adsorption magnet, toys, jewelry, etc.
