Soldering red brass

My question regards soldering red brass or NuGold. What solder is
the best match for color? I have searched the web and cannot find an
answer!

Many thanks in advance for your wisdom.

As far as im aware there isnt a matching coloured brazing alloy. What
red brass spec are you talking about? 90/10 or 80/29 cu/cz? either
make afeature of the join or design the joint so you dont see it.

Although this is not red brass, I’ve used Johnson Matthey “Mattibraze
34” to solder standard colour brass; it gives a very good colour
match, much better than normal silver solder. MP is 610-670C
(1130-1238F) and it contains Cd.

Rio Grande has a product called Solder Fast that is for brass. I am
self taught so I learn a lot of things the very hard way, and I have
had problems soldering brass, the brass melts and the post goes
straight through, I always thought it was me, or the huge torch I
have. Now, I know it must be the solder. So, my advice, do a lot of
practice first.

Sissy Watson had good advice in another post about the fire scale
that will result. For me, I like fire scale, and if you you really
want to remove it from the back try one of the little pink Radical
Discs on a Dremel or flex shaft.

Betsy, what I use is hammered pieces of a 1/16" (diameter) brazing
rod. Check the Orchid Archives for on this topic.
