Why not just buy a heavier gauge argentium sheet, if you can find
somebody with a wide-enough mill to roll it to size for you? That
would certainly be easiest. You might even get one of the current
suppliers of Argentium to do it on a contract basis.

Or if your reflectors are curved surfaces, stretch the sheet on an
english wheel. Last resort would be to forge it out yourself --
doable, but tedious in that size -- might be a little easier with a
sand bag and sheet-metal style panel beaters, though.

I talked to a couple of my suppliers who have 12" rolls and sell Argentium.

They told me they could reroll some materials but this wasn't one of them.

I was only talking to customer service reps, not the techs. So I do not know
if a licensing issue, a contamination issue or whether there is some thing
intrinsic in the alloy that precludes cross rolling.

The reflectors do not have any compound curves. I could stretch it in the
hammer work, but I would have to add at least 1/3 to the area.

That would be a whole lot of hammering.
