Home >> Magnetic Materials >> Bonded NdFeB Magnets

Bonded NdFeB magnets, i.e. bonded neodymium iron boron magnets, are those permanent magnetic materials made of rapid quenched NdFeB magnetic powders combined with resin binders (epoxy, Nylon/polyamide (PA), polyphenylene sulfide (PPS), etc). They are manufactured through a bonded process (compression, injection, extrusion or calendaring molding), so it is available to obtain complex geometries with high dimensional precision. Controlling the performance and proportion of NdFeB magnetic powders, it is able to adjust the magnets’ magnetic properties in a continuous range.

Due to their complex geometries availability, high dimensional precision, uniform magnetic properties, diverse magnetization patterns, good corrosion resistance and mechanic properties, bonded NdFeB magnets are widely applied in spindle motors, micro motors, direct current (DC) motors, synchronous motors, power tools, magnetic rollers, Hall effect sensors, etc.
