1.Stable magnetic performance
2.Powerful magnetic force.
3.High Br,high Hcj,high (BH)max,
4.Easy cutting; according customer demand to manufacture

 NdFeB, (Neodymium Iron Boron magnet,Neo magnet), is a type of rare-earth permanent magnet. It is made from an alloy of neodymium, iron,B and boron to form the Nd2Fe14B tetragonal crystalline structure. This material is currently the strongest type of permanent magnet in the world.

There are three main parameters for neodymium motor segment magnets
the remanence Br (unit: Gauss), is the magnetic energy to measure the parameters of the magnetic field strength;
coercivity Hc (unit Oersted ) is a measure of the anti-demagnetization ability parameters;
the BH(max) (unit Gauss-Oersted), is how much of the characterization can store energy in a physical quantity.
neodymium motor segment magnets have high Br,high Hcj,high (BH)max,and high stability become the important material of the world.
it has a very high energy product and coercivity, can pick up 660 times of own weight of heavy objects.

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

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.
Mostly of rare earth permanent magnet always work do not at room temperature or under vacuum, in order to keep the accuracy of shape size and avoid the Corrosion and oxidation, we must make the coating on the surface. 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.

Sometime, the customers have high demand of NdFeB anti-corrosion, antioxidant, we can design the magnet,add some elements, such as: niobium, vanadium, cobalt and other metal to replace part of the iron to catch the customer requirements of the acid and alkali resistant, antioxidant level, however, because of special material, we need MOQ for it.
