Custom Rare Earth Neodymium Block Magnets
NdFeB block magnets are non-standard products, sintered NdFeB material has good machinability and can be customized into different sizes of neodymium(NdFeB) block magnets, mold is not needed for customizing strong neodymium rectangular magnets. We can make tiny and large neodymium block magnets for any quantity.
How to Order Square Shaped Rare Earth Neodymium Magnet?
1, Choose the correct neodymium magnet grade for the block magnets according to working temperature and the needed magnetic performance.
2, Choose the correct surface treatment according to the application conditions.
3, Clear for the magnetization directions for the block neodymium magnets.
