Product Description

1, These Sintered NdFeB magnets are particularly suitable for high volumn production of a wide variety of shape and size ranges

2, Ni, Zn or customized coated surface protection. Precise dimensional control is achieved in both processed and usually the component does not require futher machining

3, NdFeB magnets have been widely used in high performance stepper, DC, servo, and linear motors, actuators, loudspeakers, headphones, instrumentation, switches, relays, magnetic imaging for medical and geophysical applications, holding systems, magnetic bearings, magnetic couplings, hard disk drives, etc.

4, Neodymium Iron Boron (NdFeB) magnets, a sort of Rare Earth magnet material, has the high remanence, high coercive force, high Maximum energy and is easily formed into various sizes, shapes. So they have been widely used in commercially available fields.

Features:
1, Many weight and size sensitive motor designs are taking advantage of NdFeB magnets materials to meet critical performance demands. Offering both high flux density and high coercivity, it is well suited for many demanding industrial and aerospace motor applications

2, The sintered form holds the highest energy product of up to 52MGOe, while the bonded form holds a lower energy product of up to 10MGOe. Furthermore, the majority of NdFeB magnets are anisotropic and can only be magnetized in the orientation direction..

3, NdFeB Magents are prone to corrosion in humid environments, It usually need surface treatment according to customer's requirements to protect magnet
