Silver Soldering Copper to Brass



These pics come from a new aerospace test facility that they are constructing at the University of Notre Dame. The SSF-6 is working great.

I am attempting to make all of these fittings air tight as they are used for pressure measurements. We can¹t have any leaks. I had very little warpage of my base metal and I think this is really going to work out very well.

SSQ-6 makes easy work of joining copper and brass. The silver paste flows effortlessly when joining the two. Brass (a copper based alloy with zinc added), is used in a variety of antiques, marine, musical instruments, household items, as well as countless other products.


Copper tubing is set flush on a brass plate awaiting the SSQ-6 silver solder paste application.



To apply the solder, just push the plunger on the syringe. No need to heat your metals before adding the solder.



Broad heating is essential to achieve an even flow around your joint. Notice the brass and copper parts are lifted from the surface with a steel wire--this prevents the table from pulling heat from our metals.  It is important to avoid heating the metals to a bright red, as this will impede the flow.



After removing the flux residue with warm water, the end result is a porosity-free, high strength professional finish with SSQ-6 Silver Solder Paste.
