Very unlikely. I've managed to melt aluminum with a propane
torch, but can't say as I've melted copper. So, the answer
is "almost certainly not".

I have a heat exchanger made up of stainless steel plates
brazed
together with copper filler. I have collected some crud
inside the
exchanger that I can't for the life of me get out. I was
thinking of
just placing the heat exchanger on my propane turkey fryer
on low for
an hour or so to try to incinerate the crud inside and turn
it into
ash. However, I don't want to melt the copper brazing and
make the
unit useless. I have little experience with brazing, and
never with
copper. Does anyone know if a propane flame will heat the
brazing to
the point of melting?

Thanks.
