The main cause of ndfeb strong magnet aging is introduced

by:Newland     2020-04-11
City magnetic technology co. , LTD. Engineer tells you: ndfeb magnet aging there are two main reasons. 1, because the environment humidity and moisture or salt fog corrosion 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. 2, the temperature of the environment more than can withstand temperature ndfeb magnets have N M files of different materials, such as brand. 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. A: magnetic technology of international currency and financial beauty magnetic industry at home and abroad under the basic details of an article: powerful magnet daily maintenance
