NdFeB magnet is an alloy magnet made from Nd,Fe,B and other metal elements,which has the high remanence,high coercive force,high energy and high performance/cost ratio.The highest magnetic properties is from 33MGOe to 52MGOe,and we are able to control the magnetic properties within the range as you demanded,like SH,UH,EH such high stable properties could be produced as per your industrial application.
We focus on Sintered NdFeB magnet and develop it under experienced engineer and passionate&studious sales team.

Key Advantages of Neodymium Magnet:
Neodymium Magnet are the most powerful commercially produced magnets.
Neodymium Ring Magnet have a higher Maximum Energy Product, (BH).max, which can easily reach 30 MGOe and even goes up to 50 MGOe.
Neodymium Magnet can replace SmCo magnets in most cases, especially where operating temperature is less than 80 degrees Centigrade.
Neodymium Magnet has very high strength.
Relatively low cost.
Compared to Alnico and SmCo magnets, relatively easy to machine
