Product Description

Cylinder NdFeB Magnet with Mark

Ndfeb permanent magnet is based on the intermetallic compound Nd2Fe14B.

The main components are neodymium (Nd), iron (Fe) and boron (B).

Of rare earth elements mainly for neodymium (Nd), in order to obtain different performance available parts of dysprosium (Dy), praseodymium (Pr), and other rare earth metals, iron can also be cobalt (Co), aluminum (Al) and other metal parts replacement, boron content is smaller, but to form a square crystal structure between the metal compounds play an important role, make compounds with high saturation magnetization, high uniaxial anisotropy and high Curie temperature.

The third generation of rare earth permanent magnet Neodymium iron boron is the most powerful permanent magnet among contemporary magnets. Its main raw materials include the metallic element iron 63.95-68.65%, the metallic element iron 63.95-1.2%, the non-metallic element boron 1.1-1.2%, the dysprosium 0.6-8%, niobium 0.3-0.5%, aluminum 0.3-0.5%, copper 0.05-0.15% and other elements.

identify

1. Usually place a magnet of the same specification on a plane that can be absorbed, such as patch, blade, iron gate, etc., and use the handle to identify the size of the magnetic force

2. Use electronic balance: the weak magnetic force and its density is generally related, the density is small magnetic force is relatively small, the weight is heavy magnetic force is relatively large, on the contrary, the light weight magnetic force is small if the requirements of the magnet is high you need to test the instrument.
