--Coincidence! I just flattened 4 rolls of .010in. shim steel, 
using a 3-roll type of bending roll. I used the one made from plans run 
in M.E. maybe a decade ago. Sorry, don't know the exact date, but it's a 
good unit to build, not too difficult and very effective at doing its 
thing...

Annealing might do the job.
Commercially available rolled sheet 'on the roll' is usually not annealed.
Brass, silver and gold alloys can simply be annealed by heating them until
cherry red and then quenching into water.

I made a bracelet out of sterling silver with some fairly fine wire
soldered to the surface. The wire was formed into spirals, and the hard
part was getting the spiral to lay flat for soldering. I heated the wire
up until it sagged flat on the sheet I was going to solder to.

Applying this to your sheet flattening could be tough due to uneven
heating. Maybe you could flatten pieces in an oven (over a piece of
steel/cast iron)?

Some snipped here....

All of my Al sheet stock that is under .040 comes from the vendor in
rolls. All we do to flatten it is to roll out the approximate amount
that we need on the work table and flip it over so that the edges curl
towards the table.  We then trim the sheet and use either 1x4's with
sandbags or a sheet of 3/4 plywood to weight the material down for a
few hours. No more curling then...If we are in a hurry and there are
at least 3 of us there, we carefully roll the material back up  the
opposite direction. It doesn't always come out completely flat, but
close enough for what we are doing...
