I wonder what the pewter I have would work like, it's 92-6-2, 92% tin,

I thinbk Pewter is too brittle to be rolled into tubes.

You haven't tried working the stuff then, I can spin a tankard from a
flat disc without any anneals. In high school people regularly formed it
into tubes and soldered the joints. I have never seen it act in a brittle
fashion.
Then the stuff I thought was pewter must not have been. Probably some
cheap zinc imitation.

Yes, tin, antimoney and copper sounds like an alloy that should be easily
worked.

Pewter alloys are wacky, in that they get softer and more malleable with
cold working.
Freshly cast they are fairly brittle and hard because the crystals are big
and chunky. As you work them the grain gets more refined and they work like
butter.
