NdFeB Permanent Magnet
NdFeB Permanent Magnet Features:
NdFeB magnet is an alloy magnet made from Nd,Fe,B and other metal elements,which has the high remanence,high coercive force,high energy and high performance/cost ratio.The highest magnetic properties is from 33MGOe to 52MGOe,and we are able to control the magnetic properties within the range as you demanded,like SH,UH,EH such high stable properties could be produced as per your industrial application.
We focus on Sintered NdFeB magnet and develop it under experienced engineer and passionate&studious sales team.
Coating: Ni+Cu+Ni, 3 layer plating, the best plating available.
About Neodymium Magnets: Neodymium magnets are the strongest permanent magnets and are also known as NdFeB magnets, but many people simply call them super strong magnets or super powerful magnets because of their incredible strength. The major elements of this magnet include neodymium (Nd), iron (Fe) and boron (B), or NdFeB.

NdFeB Permanent Magnet production process:
Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets). The powdered mixture is pressed under great pressure into molds. The material is then sintered (heated under a vacuum), cooled, and then ground or sliced into the desired shape. Coatings are then applied if required. Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field in excess of 30 KOe.
