Aluminum Cold Rolling
I need strip or foil in a gauge and flatness a mill coil will not hold. Who rerolls it, and how thin can they go?
What it is
Reducing sheet or strip below recrystallization temperature to achieve tighter gauge control, better surface finish and higher strength, followed by annealing.

Arconic Verified
Cold rolling named explicitly, producing coil, sheet and plate to gauge and finish. Specific alloys and thickness ranges are not published on the rolled products page.

Constellium Verified144 in mill width; 5083 plate 3 to 10.5 in thick
144 inch cold mill at Ravenswood, West Virginia, restarted November 2021 after a complete teardown of the 1950s-era machine under a DoD grant of nearly $9.5 million. Cold rolling here improves plate flatness, surface, internal stress and strength in 5xxx alloys, which is exactly what armour plate is graded on.

JW Aluminum Reported
Rolling mills, annealing and slitting for foil and fin stock gauges. Foil gauge is a cold rolling result by definition. Recorded from the product range; held at medium.

Kaiser Aluminum Reported
Cold rolling to gauge for sheet, strip and coil. Recorded from the plant's own identification as a flat rolled products mill rather than from a named process step: flat rolled strip and sheet is by definition rolled, and this is a producing mill rather than a distributor. Held at medium for that reason.
