Can you solder brass to copper jewelry? “Hard” solders are alloys that melt at slightly lower temperatures than the corresponding metal pieces to be fused. Silver and gold jewelry require hard soldering. Copper, brass, and bronze components can also be fused with hard solders.
Can you solder copper and brass together? As an alloy of copper and zinc, brass is compatible with copper, and manufacturers produce many common plumbing fittings with the material. Solder adheres as well to brass as it does to copper, so the fittings are usually molded with slip joints so you can solder them to the pipes.
What kind of solder do you use for copper jewelry? Solder, a metal alloy of silver and copper or silver and zinc, is used to join two pieces of metal together. Solder is heated until it flows and then allowed to cool. Once cooled, the join is permanent (if done properly). Use silver solder when soldering copper, brass, sterling silver or silver-filled metals.
What solder will stick to brass? If you have done any electronic soldering you probably used a lead based solder. This is fine for soldering electronic components together but isn’t really strong enough, nor does it give a great bond, to copper and brass. Your best option is to use a silver solder.
