NdFeB magnet is made from an alloy of neodymium, iron, andboron to form theNd₂Fe₁₄B tetragonal crystallinestructure. This materialis currently the strongest type of permanent magnet inthe world.

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

NdFeB has a very high energy product and coercivity,canpick up 660 times of own weight of heavy objects.

The advantage is high cost-effective, with good mechanical properties,easycutting; according customer's demand to manufacture in a wide range ofshapes,sizes and grades.

Also have high Br,high Hcj,high (BH)max,and high stability becometheimportant material of the world.

The shortcoming is the low of the Curie temperature and thetemperaturecharacteristics, easy to rust, oxidation, Sintered NdFeB's surface isusuallyrequired for plating such as zinc, nickel, silver, gold, etc., can alsobe donephosphorus treatment or spray epoxy resin to slow down the oxidationrate.
