Re: Working with copper
silver solder is pure (or very close to it)and requires a special flux.and usually more heat than propane.
Mapp gas is hot enough for this application methinks.
regular solder is tin and lead in varying degrees depending on its intended use.
silver solder is frequently used in the process of joining bandsaw blades made of high carbon steel.
if your plan is to use a washer,sand off the plating before trying to solder.
