The main cause of ndfeb strong magnet aging is introduced

Aging, believe that everybody is not strange, machinery and equipment parts will be aging, as to how, see the protection situation, ndfeb permanent magnets will be aging, so what are reasons that affect aging in ndfeb strong magnet? Ndfeb aging, there are two main reasons. 1, damp and wet or salt fog environment, does not favor the ndfeb preservation. For a long time in such an environment makes ndfeb surface corrosion, which produce ndfeb aging. The solution is coating should choose the film of salt spray test for 24 hours or longer 48, 72 hours salt spray test coating. Unclear magnets plating recommend reading the ndfeb strong magnetic surface treatment have? 2, high temperature ndfeb have N M gear such as different material grades. Different grades, the highest working temperature and Curie temperature. Such as the brand of ndfeb N gear, its highest working temperature is 80 ℃. More than the temperature, the will of ndfeb magnetic losses. Curie temperature, will completely lose the magnetism. In general, the highest temperature is reached can produce damage to the magnet, resulting in a summary of the aging damage. More than two of the major causes of aging is affecting ndfeb, Ricky xiaofu by dongguan powerful magnet factory card finishing editing, see more ndfeb magnet products: http://www. 勇气, 磁铁。 com/chanpin/chanpin_125_1. html
