ALUMINUM STOCK WITH GRANITE FACE PATTERN, AND METHOD FOR PRODUCING THE SAME

PROBLEM TO BE SOLVED: To provide an aluminum stock with a granite face pattern, which is inexpensive and easily molded instead of natural granite. SOLUTION: The aluminum stock has a granite face pattern on the surface by allowing the coarse recrystallized grains and fine recrystallized grains to be dispersed uniformly in macro visual sense, wherein the occupancy ratio of recrystallized grains of 4,000 to 400 μm by a diameter of the equivalent circle is 90.0 to 99.5%, the occupancy ratio of recrystallized grains of 250 to 100 μm by a diameter of the equivalent circle is 10.0 to 0.5%. The production of the aluminum stock with the granite face pattern is performed through strain introduction and annealing. COPYRIGHT: (C)2007,JPO&INPIT
