Stay-Silv® White Brazing Flux This is a white paste flux that's used for 90% of silver brazing applications. White flux is useful for brazing copper, brass, steel, stainless steel, and nickel alloys. It has an active temperature range of 1050 -1600°F (565 - 870°C).
Incidently, do you need flux for silver solder?
When you're soldering you should always use flux. Don't even use flux on the fitting (the edge). If you're using silver solder – that is, solder with 45 percent silver or higher – to connect copper to steel you must always use an acid-based flux.
But, how do you make flux for silver soldering?
Measure 1 cup of borax. ...
Pour 1 cup of potash into a measuring cup. ...
Measure 1/2 cup of table salt. ...
Mix the three ingredients together until they are fully combined.
Pour the flux mixture into a lidded jar. ...
Use the flux dry. ...
Modify amounts used in this recipe to suit your needs.

Can I solder without flux?
It's ok, if you can do it, but it's very difficult to solder without flux. The flux breaks down the oxide layers on the metal surfaces and allows the solder to "wet" them. If it doesn't wet, it doesn't make a connection. ... It's normally always necessary to use flux when you solder.

What can I use as a substitute for flux when soldering? Rosin. As you probably know, flux is usually a mixture that rosin is as the main component, which is an auxiliary material to ensure the smooth progress of the welding process and whose main component is C20H3002.
Silver solder usually refers to a stronger solder used for mechanical joins (compared to lead solder which is soft and relatively weak). However, silver solder has a higher melting temperature, which means the parts have to be heated to a higher temperature to make it work.
Be sure to get some flux, and be sure it's specifically for use with silver solder. An ordinary household propane or butane torch will work, but even better is one of the new torches that burn MAPP gas. ... They burn much hotter than ordinary torches, which makes silver soldering go faster and easier.
Flux. A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off. ... Borax is often used as a flux for forge welding.
For use with sterling silver, Argentium® sterling silver and fine silver. Medium Grade Silver Solder Cadmium-free solder, available in your choice of sheet or wire. Both forms melt at 1275° F (691° C). Excellent for the middle stage of soldering a complex piece with many joints.
While solder is used to assemble components onto your circuit board, the flux is used prior to assembly to prepare and help your board through the soldering process. ... Flux is available in liquid, paste, and solid forms, and there are different factors that go into deciding which type of flux should be used.
The flux also protects the metal surfaces from re-oxidation during soldering and helps the soldering process by altering the surface tension of the molten solder. Flux is made up of a base material and an activator which is the chemical that promotes better wetting of the solder by removing oxides from the metal.
Rosin core flux solder has the flux embedded into the core of the solder and should not need any additional flux added, although it would not hurt. Be sure NOT to use acid flux on electronic or electrical connections.
Steel wire, screwdrivers, nails, and Alan wrenches are all potential tools for your emergency soldering. Just heat your wire or other steel tool over some open flame for 20-30 seconds and then proceed to solder as you normally would.
Flux removes oxidation from metals, and it's crucial because solder won't stick to oxidized metals, and metals oxidize very quickly at soldering temperatures. 3. Not enough heat: A 15 Watt iron is fine for small chips, but any larger connectors or wire bigger than 16 gauge will cause problems.
Flux prevents the copper from oxidizing as you heat the copper with the torch. ... You can solder without flux, but it is really difficult! Flux is applied to both the pipe and the fitting with a handy miniature paint brush. You do not need massive amounts to be effective.
Stainless steel and high alloy steel have a low solderability because the chromium alloying element creates oxides that require aggressive fluxes. The only way that the final category of metals can be soldered is by pre-plating them in a metal that is solderable.
