n52 rectangular block magnet 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.

Block Neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance. Their maximum energy product can be 35MGOe~50MGOe , Block Neodymium magnets are marinly used for generator and other industrial application.

neodymium rectangle 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 neodymium rectangle magnet is over 30,000 Oe.
