Neodymium Arc Magnets
Ningbo Beilun Meank Magnetics Co.,Ltd. Is known as a 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 strong neodymium(NdFeB) magnets in arc/segment shape are mainly used in permanent magnet motor,and called neodymium magnetic tile.strong neodymium(ndfeb) magnetic tile is mainly used in permanent magnet DC motor.There are various kinds of magnet arc: neodymium motor magnets, NdFeB arc magnets, large neodymium arc magnets, neodymium arc magnet, if you want to know the arc magnet price, you can click our offical website.
urface Treatment is Needed for Strong Neodymium(NdFeB) Segment Magnets
Strong neodymium(NdFeB) arc/segment magnets are not rust-resistant and easy to corrode, and its surface need to be coated, generally including zinc plating, nickel, environmental protection zinc, environmental protection nickel, nickel copper nickel, environmental protection nickel copper nickel,epoxy coating etc.

Magnetization Direction of Powerful & Strong Neodymium Ndfeb Arc Magnets
The magnetized direction of powerful neodymium(NdFeB) ring magnets generally divided into radially magnetized and diameterly magnetization, which is determined according to the required working face.Please let us know the magnetization direction when you send us inquiry for strong neodymium arc magnets.
Custom Strong Large Neodymium Arc Magnets
Neodymium arc magnets are custom magnetic tiles,sintered Nd-Fe-B material has good machinability and c.an be customized into different sizes of neodymium(NdFeB) arc/segment magnets,mould is not necessary for customizing strong neodymium arc magnets.We can make machine strong neodymium magnetic tile for all kinds of motors.Please provide drawings when you inquiry and order strong neodymium arc magnets for use.
