Default beginner's questions about soldering

From other threads regarding the joining of aluminium with these
special rods you can buy, they are apparently very high in zinc. It
would be interesting to see if you could join aluminium to steel or
galvanised steel with them.


One day I was trying to melt a small soup can of zinc on the stove...
An hour later it was just barely melted and I gave up, poured off what
I could and busted out the rest. Problem is... it was stuck. Had to
peel the can off the zinc block! Basically it soldered itself on.
Any steel-zinc joint will be similarly weak, just like any other soft-
soldered joint.
I've tried said aluminum brazing before, seems to work. I bet if you
tinned the aluminum and steel with the rod, then stuck them together
(with a bit of flux of course) it'd work. The weak point would be the
zinc/steel joint.

From my metal melting experience I don't see why you wouldn't be able to
braze steel with aluminum, only problem is flux.
