Bit of an odd question, but I would like to buy some thin brass strips,
but no idea how 'thin' when looking at quoted measurements.

What I would like is brass strip as used on old 4.5v batteries. Firm
yet springy. Does that make sense? What sort of thickness should I be
looking for? I know how long and wide I need.
I disagree about it being phosphor bronze on throwaway batteries - too
expensive and you could easily make permanent bends in those strips for
some torch applications. Plus they were the wrong colour for PB which is
a bit more coppery than plain brass.

Springy enough to keep an electrical contact yes but not really a spring
in the sense of operating in a mechanism, where phosphor bronze is the
correct material to use.

I suspect the gauge on the "flat" torch battery would have been about 24
SWG.
