Detailed Product Description

Neodymium-iron-boron magnets are the best magnetic material developed recently, their magnetic characteristic is more excellent than alnico and ferrite kinds. Its composition is nd2 fe14 b.

Because of the highest energy products ever available in production permanent magnet materials, ndfeb has been widely used in high performance stepper, servo, and linear motors, actuators, loud-speakers, headphones, instruments, switches, relays, magnetic imaging for medical and geophysical applications, holding systems, magnetic bearings, magnetic couplings, hard disk drives etc. Sensitive motor designs are taking advantage of ndfeb magnets to meet critical performance demands. Because of both high flux density and high coercivity, ndfeb magnet is well suited for many demanding industrial and aerospace motor applications.

Ndfeb magnet can be made as small as 1 dia x 1 tk disc or even smaller parts as 0.5mm thickness. But due to the material is very easy to be oxidized, it is normally need surface treatment by nickel, zinc or epoxy coating. Bmm can supply a variety of sintered ndfeb magnets and bonded ndfeb magnets, including high hc, high working temperature type.
