Product Description
picture show the powerful ndfeb round magnet with NiCuNi coating.
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.
Bonded NdFeB also have two kinds magnet: Bonded compression NdFeB and Bonded Injection NdFeB
Nd-Fe-B permanent magnet is manufactured in a wide range of shapes, sizes and grades according customer's demand.
NdFeB has a very high energy product and coercivity, can pick up 660 times of own weight of heavy objects.
The advantage is high cost-effective, with good mechanical properties, easy cutting; according customer's demand to manufacture in a wide range of shapes, sizes and grades.
Also have high Br,high Hcj,high (BH)max,and high stability become the important material of the world.
The shortcoming is the low of the Curie temperature and the temperature characteristics, easy to rust, oxidation,Nd-Fe-B permanent magnet with its excellent performance, abundant raw material and reasonable price is to be rapid development and wide application.
Also becoming increasingly popular across a wide range of novelty products for markets.
