摘要： An aluminum foil to be etched for use as the electrolytic condenser electrodes is composed of a foil body of an aluminum purity of 99.9% or higher, and an oxide layer 20-70 .ANG. thick and formed due to contact of the foil body with an oxidizing atmosphere. At least one etching nuclei-forming element is concentrated in a boundary region and/or in an outermost surface region of the oxide layer, the boundary region being disposed between the foil body and the oxide layer, and both the regions having a thickness of 20 .ANG. or less. The ratio in ion intensity of a maximum concentration of the elements in these regions to a concentration of the elements in the inner layer of the foil body is 1.2-30. There are three patterns in distribution of the elements, so that the maximum concentration is in a predetermined ratio to the concentration in the surface region, the inner layer or a minimum concentration appearing between the regions. The foil will be etched to be ready for use as the electrolytic condenser electrodes.
摘要翻译：要用作电解电容器电极的待蚀刻的铝箔由铝纯度为99.9％以上的箔体和由箔体与氧化物接触形成的氧化物层20-70厚的氧化物层构成大气层。至少一个蚀刻成核元件集中在氧化物层的边界区域和/或最外表面区域中，边界区域设置在箔体和氧化物层之间，并且两个厚度为20的区域 ANGSTROM或更少。这些区域中的元素的最大浓度与箔体内层中元素的浓度的离子强度之比为1.2-30。在元件的分布中存在三种图案，使得最大浓度与表面区域中的浓度，内层或区域之间出现的最小浓度成预定比例。箔将被蚀刻以准备用作电解电容器电极。

摘要： A heat exchanger comprises tubular elements and fin members. The tubular elements are made of an aluminum alloy containing 0.05 to 1.0 wt % of Mg, 0.2 to 1.2 wt % of Si, 0.2 to 1.5 wt % of Mn, 0.01 to 0.5 wt % of Fe, as necessary components, and further containing at least one of 0.05 to 0.3 wt % of Cr and 0.01 to 0.05 wt % of Ti, as optional auxiliary components, and 0.05 or less wt % of Cu as a controlled impurity, the balance being aluminum and unavoidable impurities. The fin members are made of another aluminum alloy containing 0.05 to 1.0 wt % of Mg, 0.2 to 1.2 wt % of Si, 0.2 to 1.5 wt % of Mn, 0.01 to 0.5 wt % of Fe, and further containing at least one of 0.01 to 0.1 wt % of In and 0.1 to 2.0 wt % of Zn as necessary components, and still further containing at least one or of 0.05 to 0.3 wt % of Cr and 0.01 to 0.05 wt % of Ti as optional auxiliary components, and 0.05 wt % or less of Cu as a controlled impurity, the balance being aluminum and unavoidable impurities.
