product  name  Sintered Arc Ndfeb magnet for speaker 

Product Name:Hot sale rare earth permanent Sintered Ndfeb magnet

1)   Neodymium Magnets are the strongest magnets in the world., whose temperature resistance can reach 200 centigrade.

2)   Neodymium Magnets are easy to machine, compared to Alnico and SmCo magnets.
Not so easy to be scrapped

3)   . Neodymium Magnets are with high resistance to demagnetization, which makes its property quite Stable

4)   .Magnetic characteristics of Neodymium Magnets:
The choice of Strip casting and HDDR technology in our factory allows us to make high performance Neodymium Magnets of N52 possible.

5)   for big blocks.Our post processing department can reach a pretty high precision, which is quite difficult for other factories.
