Neodymium Block Magnets
Ningbo Beilun Meank Magnetics Co.,Ltd. Is known as magnets supplier, which began to machine and sell neodymium-iron-boron magnets 12 years ago. After years of accumulation of industry knowledge and exploration of experience, In 2013, the company introduced the production equipment of metal parts(turning machine and punching machine which for steel cups/iron shells), and started the processing and assembling of magnetic parts and magnetic devices. (Magnetic devices also known as magnet/magnetic assemblies, which are magnetic system with the application of magnetic circuit principle.)
The square shape strong neodymium (NdFeB) magnets are given the name of rare earth neodymium(NdFeB) block magnets or rectangular magnets,one strong NdFeB block(rectangular) magnet is expressed by length(L) x width(W) x thickness(T) / height(H).The strongest rare earth magnet blocks are made of neodymium.We provide NdFeB block magnets, neodymium magnet blocks, block neodymium magnets, square shaped magnet, neodymium block, square rare earth magnets, square magnets for saleand other products for customers.

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.
