Nd-Fe-B permanent magnet is manufactured in a wide range of shapes, sizes and grades according customer's demand.

product:permanentneodymium Iron Boron block magnets

The grade and its details properties, pls see follow table.


A neodymium magnet (also known as NdFeB, Neodymium Iron Boron magnets Neo magnet), is a type of rare-earth permanent magnet. It is made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. This material is currently the strongest type of permanent magnetin the world.
There are two kinds of magnets: Sintered NdFeB magnet and bonded NdFeB magnet.
This NdFeB magnet block is Sintered NdFeB magnet,the magnetized through the thickness.
NdFeB has a very high energy product and coercivity, can pick up 660 times of own weight of heavy objects.
Theadvantage is high cost-effective, with good mechanical properties, easycutting; according customer's demand to manufacture in a wide range ofshapes, sizes and grades.
The shortcoming is easy to rust,oxidation, so the Sintered NdFeB's surface is usually required forplating such as zinc, nickel, silver, gold, etc., can also be donephosphorus treatment or spray epoxy resin to slow down the oxidationrate.
