ABSTRACT:
Improved aluminum alloys are disclosed which are particularly useful as foil material in electrical capacitors. These alloys may contain either titanium in an aluminum base or a titanium and boron mixture in an aluminum base. The particular combination of titanium and boron presents a greater increase in capacitance in foil formed from this alloy than the increase in capacitance due to titanium or boron alone. Particular processing of such alloys is also disclosed.
