Product Description

 

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 thin&long neodymium rectangle magnets are give another name of strong neodymium(NdFeB) bar or strip magnets, The same as normal block(rectangular) neodymium magnet, neodymium bar and strip magnets also expressed by length(L) x width(W) x thickness(T).

 

Types of Neodymium Bar Magnets: neodymium strip magnets, neodymium magnet bars, simple bar magnet, neodymium bar, rare earth bar magnets, bar shaped magnet, magnetic flat bar and so on, if you want to know bar magnet cost, please contact us.

 

Surface Treatment of Strong Rare Earth NdFeB Bar Magnets

 

Strong neodymium(NdFeB) bar magnets are 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 Magnet Bars

The magnetized direction of powerful neodymium(NdFeB) bar&strip magnets can be magnetized through all direction, which is determined according to the required working face.Please let us know the magnetization direction when send us inquiry.

 

Custom Strong Neodymium(ndfeb) Strip Magnets

Neodymium bar&strip magnets are non-standard products,they are made according to customers’ need.Sintered neodymium material has good machinability and can be machined into different sizes of neodymium(NdFeB) bar magnets,mould is not needed for customizing strong neodymium bar or strip magnets.We can make tiny and large neodymium bar magnets for any quantity.
