Abstract (en)

[origin: EP0887430A1] Disclosed is an aluminum alloy support for a lithographic printing plate, which is excellent in both fatigue strength and resistance against repeated bending, particularly, irrespective of the rolling direction. The aluminum alloy support contains 0.20-0.50 wt% of Fe, 0.05-0.20 wt% of Si, and 5-300 ppm of Cu, the balance being Al and inevitable impurities, wherein an aspect ratio of each of crystal grains in a micro-surface structure is within a range of 6 to 30. Further, in the aluminum alloy support, the yield strength is within a range of 145 to 190 N/mm<2>, the fatigue strength is within a range of 4 x 10<4> or more, and the number of repetitions of bending is 8 times or more.
