Bonded NdFeB magnet is usually made of NdFeB alloy powder mixed with epoxy resin by repression, can also be mixed with plastic by injection or extrusion molding. It is of high magnetic performance, high dimensional accuracy, variety of shape, corrosion resistance, diversification of magnetization, suitable for high-volume, high production efficiency. Mainly used in a variety of micro motors, such as spindle motors, stepper motors, synchronous motors, DC motors, brushless DC motors…

Bonded NdFeB is easily machined. Coolants must be used while machining this material in order to avoid spontaneous combustion of powder. Machining this material removes a layer of protective coating, and re-coating for corrosion resistance may be necessary.
