Product Description

 

The company's magnetic assemblies products cover a wide range of types & sizes, including neodymium cup(pot) magnets, ferrite(ceramic) cup/pot magnets,plastic&rubber coated holding magnets，fishing magnets, all kinds of hook magnets, channel magnets, different types of office magnets and so on. In addition to the regular sizes for magnet assemblies, the magnets company completes the processing and assembling of many customized magnets assemblies products every year.

 

The strong neodymium(NdFeB) cone magnets are special disc or cylinder magnets that the two ends have not the same size. One rare earth strong neodymium cone shaped magnets is expressed by bottom diameter(D1)x top diameter(D2) x thickness(T).

 

Surface Treatment is Needed for Rare Earth Strong Cone Shape Neodymium Magnets

 

Strong neodymium(NdFeB) cone 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 NdFeB Cone Magnets

 

The magnetized direction of powerful neodymium(NdFeB) cone magnets generally divided into axially magnetized and diameterly magnetization, which is determined according to the required working face.Please tell us which end is N-pole when you order cone shape strong neodymium magnets from us.

 

Custom Rare Earth Neodymium(NdFeB) Cone Magnets

 

 

Neodymium cone magnets are non-standard products,sintered Nd-Fe-B material has good machinability and can be customized into different sizes of neodymium(NdFeB) cone magnets,mould is not necessary for customizing powerful neodymium cone magnets.We can make machine cone shape neodymium magnets for any quantity from tiny size to large size.
