Yes you can mix-and-match Argentium and regular sterling, and fine
silver aswell. Sometimes one has to, because findings are not
available in Argentium, or you are using fine silver for a bezel.
BTW, I haven’t used fine silver for a bezel since switching to
Argentium as it is so malleable and works in avery similar manner.
Remember that Argentium has the lowest melting point of all of
these, so useArgentium solders. They have lower soldering
I like working most times with medium Argentium solder. It has nice
color match, and has a reasonable melting point. I also use easy and
X-easy if I’m assembling pieces where there are other joints close
by. Note that are Argentium has different conductivity properties
than sterling-slightly less fast. So it is possible to overheat a
spot quicker, if you are used to working on sterling.
