Neodymium iron boron classification:
Neodymium iron boron into sintered NdFeB and bonded NdFeB two, bonded NdFeB all directions are magnetic, corrosion resistance; sintering neodymium iron boron because of easy corrosion, surface required coating, generally have galvanized, nickel, zinc, nickel, nickel copper nickel, green environment-friendly nickel copper nickel. Sintering neodymium iron boron generally magnetized in the axial direction and radial magnetization, according to the working face need to set.
Neodymium iron boron introduction:
NdFeB materials containing neodymium and iron in large amounts, easy to rust. So the neodymium iron boron magnet must be surface coating treatment. Surface chemical passivation is one of the current solution is very good. NdFeB has a very high energy product and coercive force, at the same time, the advantages of high energy density of the Nd-Fe-B permanent magnetic materials have been widely used in the modern industry and electronic technology, so that the instrument, electro acoustic electric, magnetic magnetization equipment miniaturization, lightweight, thin possible. The advantages of neodymium iron boron is cost-effective, with good mechanical properties; the shortage is that the Curie temperature point is low, temperature characteristics is poor, and easy powder corrosion, must surface treatment method by adjusting the chemical composition and taken to make improvements, in order to achieve the requirements of practical application.
