ALUMINUM ALLOY THIN PLATE FOR ELECTROLYTIC CAPACITOR, LAMINATED THIN PLATE, AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an aluminum alloy thin plate for an electrolytic capacitor which has a high VC value and low melting temperature, and to provide a manufacturing method thereof. SOLUTION: The aluminum alloy laminated thin plate for the electrolytic capacitor is obtained by uniformly dispersing and incorporating at least one kind of powder of valve operating metal except Al in an aluminum base material with≥99.9% purity by 3 to 90% for the weight of the aluminum alloy thin plate for the electrolytic capacitor, or cladding a flank of an aluminum thin plate with≥99.9% purity or aluminum alloy thin plate with the aluminum alloy thin plate for the electrolytic capacitor; and the method for manufacturing the aluminum alloy thin plate for the electrolytic capacitor in which at least one kind of valve operating metal except Al is dispersed and incorporated in aluminum powder with≥99.9% purity or molten metal by 3 to 90% for the weight of the aluminum alloy thin plate for the electrolytic capacitor. Plastic processing including rolling formation of≥95% in sectional area reduction rate is performed to obtain a thin plate. COPYRIGHT: (C)2006,JPO&NCIPI
