More Information
Summary:A high-strength aluminum alloy extruded material contains Si: 0.70 to 1.3 mass %; Mg: 0.45 to 1.2 mass %; Cu: 0.15 to less than 0.40 mass %; Mn: 0.10 to 0.40 mass %; Cr: more than 0 to 0.06 mass %; Zr: 0.05 to 0.20 mass %; Ti: 0.005 to 0.15 mass %, Fe: 0.30 mass % or less; V: 0.01 mass % or less; the balance being Al and unavoidable impurities Crystallized products in the alloy have a particle diameter of a is 5 μm or less. Furthermore, an area ratio of a fibrous structure in a cross section parallel to an extruding direction during hot extrusion is 95% or more.
