Detailed Product Description
Bonded Neodymium magnets are produced using 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.
