disc ndfeb permanent neodymium magnet

permanent neodymium magnets 1)Ndfeb,smco,alnico magnets 2)High qulity and good price 3)Design according to customer's require

disc ndfeb permanent neodymium magnet:  

   Key features:

1)Neodymium Magnets has high BH value, but easy to be rusty, so we usually produce sintered neodymium magnets with plating.

2)We produce ndfeb magnet in many shapes and size, usually make strong ndfeb magnet according to our clients' requirement, or drawing.

3)Their working stability is under 80°C for low Hci Neodymium magnets and above 200°C for high Hci NdFeB magnets

4)The material is so reactive with mositure and ozygen,coating may be applied depending on the expected environment
