Product Description
Neodymium Iron Boron magnets 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 magnet in the world.
Nd-Fe-B permanent magnet can be according customer's demand to make in a wide range of shapes, sizes and grades,such as pic shows long small magnet bar.

Nd-Fe-B permanent magnet can be according customer's demand to make in a wide range of shapes, sizes and grades,such as pic shows long small magnet bar.
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, Sintered NdFeB's surface is usually required for plating such as zinc, nickel, silver, gold, etc., can also be done phosphorus treatment or spray epoxy resin to slow down the oxidation rate.
This magnet bar is coated with NiCiNi.
This magnet bar is coated with NiCiNi.
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.
