The magnetic attraction part of NdFeB is a pot magnet made of sintered NdFeB magnet, and the magnetic attraction part is made of square magnet, ring magnet or disk magnet embedded in a steel shell. Sintered NdFeB magnetic material is fragile, and the steel shell covered on the outer surface can just protect the magnetic material and avoid cracking in collision.

When the magnetic suction piece is used, the strong suction force will be firmly attached to the surface of the magnetic object, thus showing a strong vertical pull force, which is superior to the suction pieces made of other materials. Because of its strong suction and stable demagnetization resistance, its service life is greatly prolonged, and it is widely used in the market, and can be used in home, office, factory and other application fields.
