Method for making lithoplate having improved grainability
摘要
An improved method of treating an ingot to be made into lithoplate. The method also includes (a) providing a non-heat treatable aluminum alloy containing magnesium; (b) homogenizing said alloy; (c) rolling said alloy to form a sheet or plate; (d) heating said sheet or plate for a temperature and time sufficient to permit magnesium to migrate to the surface of said metal; and (e) cold rolling said sheet or plate stock to a finished gauge workpiece.
