Motor Neodymium magnet is an alloy magnet made from ND, Fe, B and other trace metal elements. It is a rare earth magnet known so far for the strongest magnetism as well as high performance (8MGOe-55MGOe) and good coercive force. Proven production process, strict quality assurance, complete technical service and remarkable cost performance.

Machining and tolerances

Neodymium 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 +/-0.05mm 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.

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.
