Key Advantages of Neodymium Magnet

 

a)      Neodymium Magnet are the most powerful commercially produced magnets.

b)      Neodymium Magnet have a higher Maximum Energy Product ,(BH).max ,which can easily reach 30 MGOe  and even goes up to 50 MGOe.

c)      Neodymium Magnet can replace SmCo magnets in most cases ,especially where operating temperature is less than 80 degrees Centigrade .

d)      Neodymium Magnet has very high strength .

e)      Relatively low cost.
