Process for the manufacture of continuous strip cast aluminum alloy suitable for can making

DETAILED DESCRIPTION What is claimed is: 1.
A process for fabricating aluminum alloy strip stock suitable for the manufacture of drawn and wall-ironed articles comprising continuously casting an aluminum alloy in strip form having a thickness up to one inch, homogenizing the strip at a temperature of about 950.
degree.
to about 1150.
degree.
F.
for up to 50 hours, cold rolling the homogenized strip by at least 25% reduction in thickness, heating the cold rolled strip to a recovery temperature of between about 350.
degree.
and about 550.
degree.
F.
, cold rolling the strip to a second reduction in thickness of at least 10%, heating the cold rolled strip to a recrystallization temperature of between about 600.
degree.
and about 900.
degree.
F.
and then, cold rolling the recrystallized strip to a final gauge having a total reduction in thickness of at least about 50%.
2.
The process of claim 1 wherein the continuous cast aluminum strip has a thickness of between about 0.
25 and about 0.
50 inch.
3.
The process of claim 1 wherein the strip is homogenized at a temperature between about 1000.
degree.
and about 1100.
degree.
F.
for about 10 to about 25 hours.
4.
The process of claim 1 wherein the first cold roll reduction effects a reduction in thickness of about 50 to about 85%.
5.
The process of claim 1 wherein the strip is heated at a recovery temperature between about 425.
degree.
and about 475.
degree.
F.
for about 2 to about 4 hours.
6.
The process of claim 1 wherein the strip is heated at a recovery temperature of about 425.
degree.
to about 475.
degree.
F.
for about 2 to 4 hours.
7.
The process of claim 1 wherein the cold rolled strip is heated to a recrystallization temperature between about 700.
degree.
and about 850.
degree.
F.
for about 2 to about 3 hours.
8.
The process of claim 1 wherein the second cold roll reduction effects a reduction in thickness of about 10 to 50%.
9.
The process of claim 1 wherein the strip is heated to a second recovery temperature after the second cold roll and prior to heating the strip to the recrystallization temperature, the second recovery temperature being in the range of about 450
