Bonded Neodymium magnets are produced using compression moulding techniques in simple tools & can be quickly machined into complex shapes. The material is Isotropic offering approximately 10 MGO or 30% of the energy seen in the sintered fully dense material. It has a maximum operating temperature of 120°C and a rather poor temperature coefficient; the Curie temperature is 340°C. Due to its high Iron content these magnets are prone to corrosion and care is needed to avoid moisture or hostile environments. It does have one major advantage over other Rare Earth magnet materials; its Isotropic nature allows it to be magnetised in any direction. It is also possible to have complex multiple pole magnetisation making it an ideal choice for the computer peripheral industries for such applications as small precision motors. Radial and multiple pole magnetisation requires special magnetising fixtures.
