High corrosion resistance and low weight loss products NdFeB Discs Magnets
There are two main standards of low weight loss test as follows:
1. USA PCT: 121±1℃, 2 atm, 95% RH, 96 hours, weight loss less than 5~10mg/cm2
2. Europe HAST: 130±2℃, 3 atm, 95% RH, 168 hours, weight loss less than 2~5mg/cm2
Due to special material formulation and manufacturing process, the corrosion resistance is so excellent that magnets can reach the strict testing requirements above. These magnets are widely used in elevator, wind generator, military and aerospace industries.
The neodymium atom also can have a large magnetic dipole moment because it has 7 unpaired electrons in its electron structure as opposed to (on average) 3 in iron. In a magnet it is the unpaired electrons, aligned so they spin in the same direction, which generate the magnetic field. This gives the Nd2Fe14B compound a high saturation magnetization (Js ~1.6 T or 16 kG) and typically 1.3 teslas. Therefore, as the maximum energy density is proportional to Js2, this magnetic phase has the potential for storing large amounts of magnetic energy (BHmax ~ 512 kJ/m3 or 64 MG·Oe). This magnetic energy value is about 18 times greater than “ordinary” magnets by volume. This property is higher in NdFeB alloys than in samarium cobalt (SmCo) magnets, which were the first type of rare-earth magnet to be commercialized. In practice, the magnetic properties of neodymium magnets depend on the alloy composition, microstructure, and manufacturing technique employed.
