30x8x8mm neodymium block magnets

Neodymium magnet is referred to as NdFeB magnet,it is tetragonal crystal formed by neodymium,iron and boron(Nd2Fe14B).The magnetic energy of neodymium magnet is higher than SmCo magnets,it has the highest magnetic energy in the world.High performance neodymium blockmagnets are the most commonly used neodymium magnet.High performance neodymium blockmagnets are widely used in electronic products.To avoid corrosion on high performance neodymium blockmagnets,protecting treatment on surface are needed for high performance neodymium blockmagnets when they are used.Neodymium blockmagnets are divided into sintered neodymium blockmagnets and bonded neodymium blockmagnets.
