circle neodymium magnet for motor mainly comprised of neodymium ,iron and boron,is the third generation of the rare-earth permanent magnets,Sintered Ndfeb is the strongest permanent magnets in the world up to date,It has excellent properties of high remanence,coercivity,and Max.energy product.

Neodymium magnet (Nd-Fe-B) is one of the highest property and strongest permanent magnet by now, are made through powder metallurgy manufacturing techniques. They are mainly composed of neodymium(32%), iron(64%), boron(1%), and a few quantity rare earth material, such as Dy, Tb, Co, Nb, Ga, Al, Cu,etc.

long rectangular neodymium magnet are hard, brittle and easily corrode.
It's moderate temperature stability.
It's working stability is under 80¡ãC for low Hci Neodymium magnets.
It's (BH)max reaches up to 51MGOe .
The intrinsic coercive force of long rectangular neodymium magnet is over 30,000 Oe.

n45 cylinder neodymium magnet has very high resistance to demagnetization High energy for size.
n45 cylinder neodymium magnet perform good in ambient temperature.
Moderately priced.
n45 cylinder neodymium magnet has low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically.
