Neodymium Bar Magnets
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).
Surface Treatment of Strong Rare Earth NdFeB Bar Magnets
Strong neodymium(NdFeB) bar magnets are easy to corrode, and their surface needs 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 strip
The magnetized direction of powerful neodymium(NdFeB) bar&strip magnets can be magnetized through all directions, which is determined according to the required working face. Please let us know the magnetization direction when sending us an inquiry.
Custom Strong Neodymium(NdFeB) Strip Magnets
Neodymium bar&strip magnets are non-standard products, rare earth NdFeB magnets are made according to customers' needs. 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.
