NdFeB magnet is made from an alloy of neodymium, iron, and boron to form theNd₂Fe₁₄B tetragonal crystalline structure. This materialis currently the strongest type of permanent magnet in the world.

Nd-Fe-B permanent magnet is manufactured in a widerange 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 of shapes,sizes and grades.

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

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

See the follows Grade N Sintered NdFeB magnetic energyparameters
