Abstract
Official abstract text for this publication.
The invention relates to an aluminum alloy lithographic sheet product having an enhanced electrolytic graining response in which Zn between 0.5 and 2.5 wt % is added to an aluminum base alloy, in particular an alloy of the 1XXX, 3XXX or 5XXX series alloys. The invention also relates to a method of producing a lithographic sheet product.
First claim
Opening claim text (preview).
The invention claimed is: 1. A lithographic sheet comprising an alloy composition comprising 0.71-2.5% Zn wherein the alloy, apart from the Zn content, is an alloy from the 1XXX series of aluminum alloys. 2. The lithographic sheet of claim 1 wherein the lower Zn limit is 0.9%. 3. The lithographic sheet of claim 1 wherein the upper Zn limit is 2.0%. 4. The lithographic sheet of claim 1 wherein the upper Zn limit is 1.…
