Simple introduction of powerful magnets manufacturers of ndfeb magnet
Strong magnet manufacturers of ndfeb magnet simple introduction in 1983, the third generation of ndfeb Na -
B, the magnetic field strength is ten times the ordinary magnet, service life is as high as more than a decade, is magnetic energy product of human society have found so far,
The highest permanent magnetic material, known as the king of the permanent magnet.
Powerful magnets are widely used in national defense, space technology, microwave, communications, electronics, health care and other high-tech fields.
Ndfeb magnetic material of the main raw materials are iron and rare earth metal neodymium (64%
32%, non-metallic element boron (
A small amount of added dysprosium (
, terbium (
, aluminum (
Elements such as)
Ndfeb permanent magnetic material based on Nd2Fe14B ternary compound as matrix, its content should be close to compound Nd2Fe14B formula is.
Nd2Fe14B composition proportion, magnets, magnetic is very low, even no magnetic.
Only actual of neodymium magnets and boron content than Nd2Fe14B compounds and neodymium boron content to get better performance of permanent magnet.
Ndfeb magnet (
Have quite high coercive force, natural environment and the condition of magnetic field will not appear demagnetization and magnetic changes.
Appropriate assumptions environment, even after a long time use, magnets, magnetic loss is not much.
So in practice, we usually ignore time factors on the magnetic effect.
But the magnet in some poor working environment may make the magnet magnetic disappeared or reduced.
Such as high temperature.
