Aluminum alloy foil, laminate, method for manufacturing aluminum alloy foil, and method for manufacturing laminate

Abstract

An aluminum alloy foil (1) is an aluminum alloy foil having a first surface (1A). The aluminum alloy foil (1) contains: aluminum; silicon; 0.4-3.04 mass% of manganese; 0.03-0.08 mass% of iron; 0.00001-0.03 mass% of zinc; 0.00001-0.02 mass% of copper; and 0.00001-0.01 mass% of magnesium. In the aluminum alloy foil (1), the total content of silicon and iron is 0.1 mass% or less. In the aluminum alloy foil (1), the mass ratio of manganese relative to the total mass of silicon and iron is 7.0 or more. On the first surface (1A), the area ratio of second phase particles having a circle-equivalent diameter of 1.5 [mu]m or more is 0.1% or less.

Description

technical field [0001] The present invention relates to an aluminum alloy foil, a laminate, a method for producing the aluminum alloy foil, and a method for producing the laminate. Background technique [0002] In recent years, from the viewpoint of reducing the environmental load, further reduction in weight has been desired for aircraft, railway vehicles, and automobiles used in moving mechanisms. In addition, from the viewpoint of handling, further reduction in weight is also desired for members used in fields such as various mechanical parts, electrical and electronic related members, building materials, and household use. [0003] Based on such a background, when metal materials are used for these components, weight reduction of components can be achieved by using aluminum and / or aluminum alloys with lower density instead of steel materials and copper with relatively high density. [0004] On the other hand, general aluminum alloys are easily corroded if exposed to wat...
