Because ndfeb strong magnet material combination is very reasonable, so making nd-fe-b permanent magnetic properties.
Ndfeb magnet with a high coercive force, the natural environment and the general conditions of magnetic field of magnetic loss will not change or lose magnetism.
Rubber magnetic manufacturers can use a few iron products of ndfeb magnetic testing, if the material is good enough magnetic also will be very big, natural magnet appeal is very big, from which we can judge the jerry-built situation does exist.
If we want to mass purchase of ndfeb magnet, also can pass the test of magnetic magnetic to judge good or bad.
Since after understanding the performance of ndfeb magnets have how well we can be used to identify it, so can the choose and buy of the ndfeb magnets in a reasonable manner.
The main raw materials ndfeb permanent magnets have rare earth metal neodymium (
32%, iron metal elements (
64% boron and nonmetallic elements (
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.
But according to Nd2Fe14B composition ratio in full, magnets, magnetic can 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.
Summary of quality determines the quality and value of ndfeb magnets, from the above summary of the main raw materials, the ndfeb belongs to a kind of magnetic material, its performance is extremely high, moderate price, and the intensity is high, but it is not resistant to high temperature and corrosion.
After long-term use, magnetic loss is too big, so it is in the process of use, time factor's influence on the magnetic can generally ignored.
With such high magnetic ndfeb magnet, make it more widely, ndfeb magnet manufacturers also more and more.
