铝合金箔
摘要：
一种铝合金箔，其化学成分由按质量％计含有Si：0.1％以上0.6％以下、Fe：0.2％以上1.5％以下，并且Si含量与Fe含量合计在0.48％以上，剩余部分为Al以及不可避免的杂质来形成；箔厚度为20μm以下，Si固溶量为700质量ppm以上，Fe固溶量为150质量ppm以上，抗拉强度为220MPa以上，在液氮中测定的比电阻为0.45μΩ·cm以上0.7μΩ·cm以下。
摘要（英）：

By mass, this aluminum-alloy foil contains 0.1-0.6% silicon and 0.2-1.5% iron, with the sum of the silicon content and the iron content being greater than or equal to 0.48% and the remainder comprising aluminum and unavoidable impurities. The amount of silicon in solid solution is at least 700 ppm by mass, and the amount of iron in solid solution is at least 150 ppm by mass. This aluminum-alloy foil is at most 20 µm thick and exhibits a tensile strength of at least 220 MPa. The resistivity of this aluminum-alloy foil, measured in liquid nitrogen, is between 0.45 and 0.7 μ&OHgr;∙cm, inclusive.
