Product Description

wind generator ndfeb magnet 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.

wind generator ndfeb magnet is manufactured in a wide range of shapes, sizes and grades according customer's demand.

wind generator ndfeb magnet 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, 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.

Pls see the compare of the coating's results:

Commonly type of coating	Coating thickness(um)				Neutral salt spray test
Commonly type of coating	dark Ni	Cu	Shine Ni	Total	Neutral salt spray test
Single-layer Ni	25			25	24h	normal
Double-layer Ni	12		10	25	72h	better
Dark Ni-Cu–shine Ni	6.25	8.75	10	25	120h	excellent
