NdFeB material is iron (Fe) 64%

NdFeB material is iron (Fe) 64%, boron (B) 1% as the basic raw material, add a small amount of dysprosium (Dy) and terbium (Tb), cobalt (Co), neodymium (Nd) 32%, niobium (Nb), gallium (Ga), aluminum (Al), copper (Cu) and other elements, the process of manufacturing an iron-based powder metallurgy permanent magnet material applications. Magnetic is a third generation, called "Magneto" NdFeB permanent magnet materials, is currently the strongest magnetic magnet applications to large-scale production of a very wide range, suitable for motor, magnetic speakers, electric toys, gifts Packed, magnetic buttons magnetic switch, stationery, and so on. NdFeB sintered magnet method, a bonding method or injection performance is very difficult, but brittle materials are bonded Nd-Fe -B method of production of high precision, good magnetic properties, good corrosion resistance, temperature stability good production of sintered products is often difficult, but relatively brittle, with high resistance to demagnetization, but the high cost, poor heat resistance, the disadvantage NdFeB injection method, accuracy is very high, easy forming a thin-walled complex shape anisotropy ring magnet, but is weak!
