Capacitor foil

Since the capacitance that indicates the performance of an electrolytic capacitor is proportional to the surface area of ​​the electrode foil, aluminum foil is treated by an electrochemical method so that the surface area is tens to hundreds of times larger. Therefore, while aluminum foil is required to have the characteristics that the surface area after treatment is as large as possible, it is also necessary to secure the bending strength that contradicts it.In order to meet these requirements, UACJ and UACJ Foil Co., Ltd. collaborated to use slabs made by adjusting trace chemical components to high-purity aluminum base metal, and were excellent under a special manufacturing and quality control system. We manufacture aluminum foil for electrolytic capacitors with characteristics

The surface magnification of aluminum electrolytic foil is increasing year by year, and the demands of customers are also increasing.At UACJ Foil, we perform accuracy tests on mechanical properties, performance evaluations using etching test equipment, and quality evaluations, and ship products that meet the required quality.In addition, the UACJ R & D Centeranalyzes trace components and the effects of precipitates on pit formation, and is researching improvements in process technology based on product performance tests day and night.
