Abstract
The present invention provides an aluminum alloy support body for a presensitized plate in which the uniformity of the grained surface due to electrochemical etching is further improved, and a method of producing the same. The aluminum alloy support body for the presensitized plate according to the present invention has a composition comprising 0.1 to 0.7% by weight of Fe; 0.01 to 0.2% by weight of Si; 0.005 to 1.0% by weight of one or more rare earth elements; and the balance of Al and unavoidable impurities. In the present invention, the aluminum alloy support body may further contain 0.005 to 0.1% by weight of Ni and 0.005 to 0.3% by weight of one or more rare earth elements. One or more elements of Ce, La and Nd can be selected as the rare earth elements.
