NdFeB magnets
NdFeB magnet is an alloy magnet made from Nd,Fe,B and other trace metal elements. It isa rare earth magnet known so far for the strongest magnetism as well as high performance (8MGOe-55MGOe) and good coercive force. Sine Magnets Company Limited customizes NdFeB magnets in different shapes and sizes, grades include N35~N54, N30M~N50M, N30H~N48H, N30SH~N45SH, N28UH~N40UH, N28EH~N38EH and N28AH~N35AH, coatings include Ni-Cu-Ni, Zinc, grey epoxy, black epoxy, Ni+Au, Ni+Ag, color paint, etc. Strong neodymium magnets can be shipped by express, air or by sea to overseas countries after properly packages.Proven production process, strict quality assurance, complete technical service and remarkable cost performance.
Common applications
Machining and tolerances Neodymium (we like to just call it Neo) is easily ground, although coolants must be used in the process to avoid spontaneous combustion of powder. Grinding should be completed before coating or plating is applied to protect the magnets from corrosion. Standard tolerances for neodymium magnets are +/-.005” for ground dimensions. Temperature constraints The temperature coefficient of neodymium has triggered several grades to be developed to meet specific operating requirements. Please refer to our chart of magnetic properties to compare the characteristics of each grade. Before choosing a neodymium magnet be sure to consider your application’s maximum operating temperature. Magnetization Neodymium magnets require extremely high magnetizing fields and particular consideration must be given to this when designing complex assemblies. Neodymium can be magnetized in any direction as long as it is aligned properly. In some instances multiple pole magnetization is not possible; when it is possible, special fixtures are required. Added value services Our knowledgeable engineering department is always available to assist in determining the best grade and size of neodymium magnet for your application. We also offer coating and plating choices for magnets we custom-machine.
