EXTRUDED MULTI-HOLE TUBE AND PRODUCTION METHOD FOR SAME
An extruded multi-hole tube (1) has a chemical composition that is 0.30–1.80 mass% Si, 0.10–0.50 mass% Cu, 0.30–1.00 mass% Mn, and 0.30–1.00 mass% Mg, the remainder being Al and unavoidable impurities. The tensile strength of the extruded multi-hole tube (1) is at least 290 MPa. The extruded multi-hole tube (1) is produced by holding an ingot that has the abovementioned chemical composition at a temperature of 450°C–620°C for at least 2 hours as a homogenization treatment and then hot-extruding the ingot to form the extruded multi-hole tube (1). After the hot extrusion is complete, the extruded multi-hole tube (1) is cooled at an average cooling speed of at least 1°C/sec until the temperature of the extruded multi-hole tube (1) is 150°C. The cooled extruded multi-hole tube (1) is held at a temperature of 150°C–200°C for at least 2 hours as an artificial aging treatment.

ALUMINUM ALLOY ROLLED SHEET AND METHOD FOR PRODUCING SAME
This aluminum alloy rolled sheet has a chemical composition containing 0.80-2.5 mass% of Si, 0.40-1.2 mass% of Mn, 0.25-0.65 mass% of Mg, and 0.050-0.45 mass% of Fe, the balance being Al and unavoidable impurities. In the aluminum alloy rolled sheet, the uniform elongation in a direction perpendicular to rolling is 19.5% or greater, and the anisotropy Δr value of the Lankford value ranges from –0.50 to 0. The aluminum alloy rolled sheet has characteristics such that that the 0.2% proof stress reaches 175 MPa or greater after introduction of 2% pre-strain and subsequent aging at a holding temperature of 170°C for a holding time of 20 minutes.
