Aluminum Strip Defects Affecting Capacitor Quality

(1) Coarse Grains. Coarse grains often manifest as wheat-ear crystal structure. As mentioned above, due to the lack of active crystal nuclei in electrolytic aluminum liquid and superheated aluminum melt, the energy of homogeneous nucleation is higher than the energy of nucleation on the surface of the casting roller sleeve. Therefore, during the casting process, when [...]
