Capacitor aluminum crystals and polycrystalline texture

1 Capacitor aluminum crystals—definition of orientation and texture The semi-continuous casting slab, hot-rolled plate, cold-rolled plate or final aluminum foil (Figure 1.7) involved in aluminum electrolytic capacitors are all composed of aluminum crystals. Usually, the normal direction of the aluminum plate or aluminum foil is represented by ND, the rolling direction is represented by RD, and [...]
