At various markets people set up stalls selling an aluminium soldering
(brazing) rod Which they demonstrate filling holes in aluminium cans,
also aluminium to bronze etc using LPG flame.It melts at a lot lower
temp than aluminium,they heat the can and sort of paint and puddle the
rod on and they do not use flux.
This rod looks like thin rudimentary solder sticks.
I think it is a zinc based alloy
I would like to know the formula as I think they make this alloy
themselves and pour it into sticks, I don't think it is a commercial
product.
can any one tell me which metals and the proportions it would be made from
