Bonded Neodymium

Bonded Neodymium Iron Boron (NdFeB) magnets are made by combining Magnequench powder with nylons, epoxies and other various additives. These types of rare earth magnets should be coated to ensure proper corrosion resistance.

Material Composition

Neodymium, Iron, and Boron powder bonded with a polymer binder.

Key Properties

Moderate magnetic strength, high mechanical strength, and easier to shape than sintered neodymium. Good corrosion resistance but lower temperature stability than other rare earth magnets.

Temperature Range

Injection molded stable up to around 120 – 180°C. Compression molded stable up to around 120 – 160°C.

Manufacturing Notes

Ideal for applications where high strength-to-weight ratio is required but without brittleness of sintered magnets. Suitable for molding into complex shapes and forms.

Common Uses

Magnetic clutches, magnetic bearings, precision instruments, small motors, sensors, loudspeakers, and medical devices.
