Soldering Bronze

Jewelry Discussion

Hello,

Can someone help me?

I want to solder bronze (87 Cu : 13 Sn) and I want a reasonable
color match.

Does such a solder exist and if so, what is its composition?

Many thanks in anticipation.

Probably the closest match is a cadmium bearing solder CD-35
or the cadmium free version. see the pdfs under silver alloys at:

http://www.brazing.com/products/Braze_silver/

The pdfs may take a long time to down load ,but they show a wide
range of alloys. They are not all easy to buy in the US in small
quantities

what you want is a high copper content silver alloy… The 35 has a
wide mushy range which may be desirable or not. The 45 silver has a
narrower melting range and is more fluid but not very brass
colored

I have some other US sites –

For cast sculpture we use Everdure silicon bronze and gas or tig
weld with the same filler material.

I haven’t worked with the tin alloys.

Try the various brazing rods available at your local plumbers’
supplies.
