NdFeB Magnet
Features:
1) The merit of neodymium-iron-boron is its excellent performance and cost ratio and good machinery feature of easy machining.
2) Its demerits lie in its low curie temperature, bad thermal feature, easy erosion, which should be improved to achieve desired requirement with the adjustment of chemical composition and surface treatment.
Application:
1) NdFeB magnet is the third generation of rare-earth permanent magnets and the strongest permanent magnets to date.
2) It is widely used in apparatus and instruments where a strong magnetic field is needed such as devices for avionics, spacecraft, electronic instruments, electro-acoustic devices, electrical machinery, meters and medical instruments, 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.
3) This magnet is thus especially suitable for developing those new products demanding high quality, small volume and light weigh.
4) NdFeB magnet can be used as an ideal magnet in mini-motor, permanent magnet instrument, electronic industry, auto industry, petro-chemical industry, nuclear magnetic resonance, sound device magnetic suspension system, magnetic transmission machine and iatrical apparatus and etc
