摘要： The invention is directed toward a base material for aluminium offset printing plates having improved heat stability comprising an aluminum alloy consisting of from about 0.2 to about 0.6% by weight of iron, less than about 0.25% by weight silicon and copper combined, from about 0.1 to about 0.3% by weight manganese and the remainder being aluminum and trace production impurities, said base material further characterized as containing secondary precipitates in the form of phases of the Al Mn Si: Al Fe: Al Mn type which bear a ratio to one another of from about 1:1:2 to about 1:1:3, the mean particle size being from about 0.25 to about 0.010 micron with a maximum particle size of less than about 0.3 micron and further containing a precipitation structure with a degree of dispersion of less than about 50 phases per cubic micron and a process for producing such material. The sheet material according to this invention may be uniformly roughened in either HCl or HNO.sub.3 electrolyte baths under very similar process parameters.

摘要： Non-galling, low earing can stock suitable for deep drawing and wall-ironing into can bodies is prepared from continuously cast aluminum alloy strip of an inch or less in thickness. The strip material is heated to a temperature of from 950.degree. to 1150.degree. F. for a time sufficient to homogenize the alloy. The homogenized strip material is cold rolled to effect a first reduction in sheet thickness of at least 25%. The cold rolled sheet is heated to a recovery temperature of up to about 550.degree. F., and subjected to a second cold rolling to effect a reduction in thickness of up to 50%. The cold rolled sheet product is heated to the recrystallization temperature and then subjected to effect a final reduction in thickness of at least 50% of the original thickness of the sheet to impart an H19 temper to the sheet.
