摘要： A continuous-cast and cold-rolled aluminum alloy sheet for a cross fin, characterized by a chemical composition consisting of not less than 0.05 wt % and less than 0.30 wt % Fe, more than 0.03 wt % and less than 0.10 wt % Mn, an amount of a grain refining agent, and the balance of Al and unavoidable impurities including less than 0.15 wt % Si; a microstructure substantially composed of subgrains; and an electrical conductivity of 55% IACS or more. The aluminum alloy sheet is advantageously produced by a process including the steps of continuous-casting an aluminum alloy melt having the above-mentioned chemical composition to form a cast sheet having a sheet thickness of not more than 30 mm; cold-rolling the cast sheet at a reduction of 90% or more, followed by a temper annealing at a temperature of from 250 to 300.degree. C. for a holding time of 2 hours or more. The present inventive aluminum alloy sheet has a high formability such that a cross fin having a large fin pitch applicable to any type of heat media pipe having various sizes can be successfully formed by a simplified production process which is easy to manage and also reduces the production cost, and by using less viscous volatile lubricants causing no substantial environmental pollution.

摘要： An aluminum alloy foil is formed from an alloy containing about 1.2 to 1.7% by weight Fe and about 0.35 to 0.80% by weight Si, with the balance aluminum and incidental impurities. The alloy is continuously strip cast to form a strip having a thickness less than about 25 mm, which is then cold rolled to interanneal gauge and interannealed at a temperature of at least 400° C. The interannealed strip is cold rolled and further annealed to form the final foil product, having excellent rollability combined with high strength of the final foil.
