What kind of solder to use on copper?
Just remember that if you use silver solder on copper or brass, the silver will show up against the brown or yellow of the other metals. – Hauser and Miller supplies precious metal materials such as Sterling silver wire and silver solder.
Can a copper wire be soldered to an aluminium wire?
This type commonly uses copper for one wire, giving a reddish colour, and aluminium for the other, giving a silver colour. Copper will solder easily. Aluminium won’t. For aluminium, ALL the soldering advice above is of no value or use. Aluminium CAN be soldered – with specialist techniques, solders and fluxes.
Which is the worst solder for hand soldering?
Sn99.3Cu0.7 is one of the worst solders for hand soldering. It’s wetting properties are extremely poor and it melts at 227degC. Last time I bought lead free solder from Maplin it was a much nicer composition with some silver in. All wire solder from Maplin is flux cored as far as I know.
Why does solder not stick to silver wire?
If your attempts at soldering just result in the silver wire not tinning, but disappearing in a black gunge, that is the oxide layer forming and disintegrating. If this is your problem, crimp the wire, or buy some wire which is not aluminium.
Is there a way to solder copper to brass?
Hardly a week goes by that I don’t get asked how to solder copper or other alternative metals, like brass and bronze, to each other or silver. Even though copper and brass solders (wire and paste) do exist, they’re not always on hand.

How to hide solder seams when soldering copper?
Even though copper and brass solders (wire and paste) do exist, they’re not always on hand. Here’s a great trick for making perfectly invisible seams and hiding the solder when soldering copper with silver solder. (Originally published in Lapidary Journal ‘s Dec. 9, 2008, “Flashcard” newsletter by Helen Driggs).
Which is easier to solder sterling silver or copper?
Base metals are inexpensive and less intimidating while you are learning new techniques and tools. Soldering base metals is a lot different than soldering with sterling silver or gold. Since copper is the trickier base metal, after successfully soldering with copper, switching over to sterling silver becomes an easy transition to make.
