As rare earth ndfeb permanent magnet material of a magnetic energy product and high coercive force, high energy density at the same time the advantages of ndfeb permanent magnet material in modern industry and the wide application of electronic technology, so that the instruments and meters, electronic motor, magnetization of the magnetic separation equipment miniaturization, lightweight, thin become possible.
strong 12x2 mm neodymium high torque dc motor magnets
Ndfeb magnet is a kind of product with very high magnetic energy and coercivity, and high density, so it has a wide range of
applications in industrial and electronic products.In recent years, the development of foreign permanent magnet materials industry
has slowed down to varying degrees, but due to the extraordinary development of permanent magnet materials in China, ndfeb
magnetic industry still maintains rapid development.
The grades of ndfeb magnets are n35-n52, N38SH, etc. These grades represent the ndfeb material grades.Generally speaking, the
larger the number after the letter, the stronger the magnet will be.Currently the most powerful ndfeb magnet is N52.The letter
after the grade refers to the temperature level of the magnet.If there is no letter after the grade, then the magnet is the standard
Ndfeb magnet has very poor temperature resistance and needs surface treatment to solve this problem, but the demagnetization
of the magnet is also critical. Ndfeb magnet has high anti-demagnetization ability.They don't weaken the magnetic force because
the external magnetic field around them disappears.But they are sensitive to outside temperature, and if they are heated beyond
their maximum operating temperature, their magnetic force drops rapidly.
