ndfeb magnets, also known as Neodymium magnet, the patent for Nd2Fe14B, is a kind of man-made permanent magnet. So far, this is one of the strongest magnetic materials, so called the king of the magnet.Nowadays, a neodymium magnet in rapid development and wide application. In many areas are unlikely to replace the traditional pure iron, cobalt nickel alloy aluminum magnet motor magnets such as cobalt and samarium, instrument and meter, automobile industry, petroleum chemical industry and magnetic health products. Can produce various shapes such as disk magnets, rings, rectangular magnets, magnet, arc magnet and other shapes of magnets.

Also known as neodymium iron boron magnets, the chemical formula for Nd2Fe14B, is a man-made permanent magnet.So far, this is the strongest magnetic materials, known as the king of the magnet. NdFeB magnet is found in the commercialization of highest performance magnets, known as the magnetic king, with a high maximum magnetic energy product (BHmax) higher than the ferrite (Ferrite) 10 times.Mechanical processing properties of its own some very good.Operating temperature up to 200 degrees Celsius.And its hard texture, stable performance, good value for money, so its application is extremely broad.But because of its strong chemical activity, it is necessary for its surface coating.(Such as plating Zn, Ni, electrophoresis, passivation, etc.).

We specialized in the production and sale of Neodymium Magnet, can be customized according to various Neodymium Magnets, if you need to know more Neodymium Magnet relations information, please contact us.

Feature:

NdFeB magnet is found in the commercialization of highest performance magnets, known as the magnetic king, with a high maximum magnetic energy product (BHmax) higher than the ferrite (Ferrite) 10 times.Mechanical processing properties of its own some very good.Operating temperature up to 200 degrees Celsius.And its hard texture, stable performance, good value for money, so its application is extremely broad.

Application:

Today, neodymium magnet in the rapid development and wide application.In many areas, may replace the traditional magnet iron, aluminum, nickel and cobalt alloys and samarium cobalt magnets such as motors, equipment and instrumentation, automotive, petrochemical industry and magnetic health care products.Can produce a variety of shapes: such as disc magnets, ring magnets, rectangular magnets, arc magnets, and other shapes of magnets.

Manufacturing Process
Neodymium, Iron, Boron and a few transition metals will be made into the NdFeB powder, then fine NdFeB powder will be compacted in a die and sintered, fusing thepowder into a solid material. There are 2 forms of pressing: die pressing and isostatic pressing. Sintered parts normally need some finish machining in order to meet final tolerances.

Machining & Tolerance
Generally, NdFeB magnets must be machined using diamond-grinding techniques. Sometimes, machining operations may be performed on NdFeB materials using carbide tools, but surface finishes thus obtained may be less than optimal. The Standard tolerances for NdFeB magnets are +/- 0.1mm for ground dimensions, but sticter tolerances are possible if specially required.

Surface treatments
The corrosion resistance of NdFeB magnets is considered poor. Surface coating or plating is therefore highly recommended for NdFeB magnets. All kinds of surface coating are available, like Nickel, Zn, Ni-Cu-Ni, Gold, Silver, Sn, Chrome. We also applied special surface protection to NdFeB magnets, like ABS coating, Rubber coating, PTFE(Telfon) coating, stainless steel case, etc.

Magnetizing & Packing
NdFeB magnets require extremely high magnetizing fields, and can be magnetized in any direction as long as it is aligned properly. In some instances multiple pole magnetization is possible with special fixtures.All NdFeB magnets are anisotropic, and can only be magnetized in the orientation direction, so particular consideration must be given to this when designing complex assemblies, if it is intended to magnetize after assembly.
NdFeB magnets are mechanically weak, and magnetically very strong. They should be packed properly in order to help user to use and handle them.
