If it is for lead-tin electronic soldering, the rosin flux inside the solder is mostly colophony (pine rosin). The same stuff used on violin bows, and that pitchers have it powdered in a bag. Mix it with 99% isopropyl alcohol to make a liquid.

How do you get solder to stick without flux?

Simple! HEAT, and lots of rubbing alcohol, lint free cloth, scouring pads (like scotch-brite) as well as patience; and even then it might not flow well. Air is all around us, and will cause the surface you are trying to solder to oxidize. If you surface isn’t clean, there will be no whetting action, period.

Can you use glue instead of solder?

“The metallic glue has multiple applications, many of them in the electronics industry. As a heat conductor, it may replace the thermal grease currently being used, and as an electrical conductor, it may replace today’s solders.

What is solder flux made of?

Flux is used in soldering to remove oxides from the contacts of the parts to be soldered together. Fluxes can be made from hydrochloric acid, zinc chloride or rosin.

Can I use brazing flux for soldering?

Flux Types

Because brazing takes place at very high temperatures, many of the fluxes commonly used in lower-temperature processes, like soldering and welding, can’t be used. A brazing flux must retain thermal stability at the temperatures required by the parent materials and the filler metal.
