we can make the abnormity shapes magnet according to customers' requirment or design.

irregular ndfeb magnet is made from an alloy of neodymium, iron, and boron to form the Nd2Fe14Btetragonal crystalline structure.

This material s currently the strongest type of permanent magnet in the world.

There are three main parameters for magnet.

the remanence Br (unit: Gauss), is the magnetic energy to measure the parameters of the magnetic fieldstrength;
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 physicalquantity.
irregular ndfeb magnet has high Br,high Hcj,high (BH)max,and high stability,can pick up 660 times of ownweight of heavy objects.
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., canalso be done phosphorus treatment or spray epoxy resin to slow down the oxidation rate.
