Abstract (en)

[origin: WO2007115167A2] The present invention provides an aluminum alloy for lithographic sheet including about 0.05 wt % to about 0.25 wt % Si; about 0.25 wt % to about 0.4 wt % Fe; less than or equal to about 0.04 wt % Cu; less than or equal to about 0.25 wt % Mn; 0.31 wt % to 0.35 wt % Mg; less than or equal to about 0.03 wt % Zn; less than or equal to about 0.03 wt % Ti; and incidental impurities. Another aspect of the invention is a method of processing a lithographic sheet including the steps of providing an aluminum sheet; contacting the aluminum sheet with an electrolyte bath; and applying a current having a non-sinusoidal wave form with a constant peak voltage to said electrolyte bath.
