Arc Neodymium Iron Boron magnet is made from an alloy of neodymium, iron, and boron to form the Nd₂Fe₁₄B tetragonal 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 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.

Arc Neodymium Iron Boron magnets have high Br,high Hcj,high (BH)max,and high stability,can pick up 660 times of own weight 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., can also be done phosphorus treatment or spray epoxy resin to slow down the oxidation rate.
