How Strong Is Silver Solder?

Can you solder silver with a soldering iron?


A soldering iron will not be suitable for soldering sterling silver.

You will need to use a gas torch to achieve the correct temperature..

At what temp does silver solder melt?

Alloys that melt between 180 and 190 °C (360 and 370 °F; 450 and 460 K) are the most commonly used. Soldering performed using alloys with a melting point above 450 °C (840 °F; 720 K) is called “hard soldering”, “silver soldering”, or brazing.

Can you braze with propane torch?

Brazing with Propane. Here is the answer to whether you can braze with a propane / air torch. You can but you have to control the environment so that the heat loss to the atmosphere and parts is lower than the heat being put into the braze joint. … It is a standard braze alloy that melts over a range of 1250 – 1305 F.

Can you silver solder with a TIG welder?

irondarren Member. I have to say the answer is going to be no. Tig heats up a very local area where as propane heats up a wider area, i just dont believe you would be able to get the area surrounding hot enough for silver solder to flow. The instant you take the tig torch away it would be to cold for solder to flow.

How strong is silver brazing?

The bulk tensile strength of silver braze alloys is 40,000-70,000 psi. When brazing copper-based alloys, failure will occur in the copper or brass. For copper this is usually the annealed strength of the copper alloy.

What kind of flux do you use with silver solder?

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).

Can you use too much flux when soldering?

If you are Louis Rossmann , then the answer is no, there is no such thing as too much flux. … If you are using normal solder wire, it contains all the flux you need. If you are soldering copper pipe for example, excess flux will simply probably not compromise the joint, but will simply drip away.

What percentage of silver is in silver solder?

The silver content ranges from as high as about 80 percent for very “hard” solders with high melting points, to as little as 30 percent for the industrial repair types that are generally intended for soldering metals other than silver.

Is silver solder toxic?

High, airborne concentrations of metal fumes, including cadmium, can be expected with silver soldering. Cadmium-containing fumes are extremely toxic, and acute overexposure can cause chemical pneumonia and be fatal. Chronic exposure can cause lung tissue damage, kidney damage, lung cancer, and prostate cancer.

Is solder as strong as welding?

Welding joints are the strongest, followed by soldered joints then brazed joints. Welding requires about 6,500 degrees Fahrenheit, while soldering requires about 840 degrees Fahrenheit. Workpieces and the metal base are heated and melted in welding. Soldering requires no heating of the workpieces.

Can I use Vaseline as flux?

The answer is yes. Using petroleum jelly as a soldering flux is an effective soldering flux alternative.

Can I silver solder with a propane torch?

An ordinary household propane or butane torch will work, but even better is one of the new torches that burn MAPP gas. Most hardware stores have them. They burn much hotter than ordinary torches, which makes silver soldering go faster and easier. Use silver solder like ordinary solder.

Do you need flux with silver solder?

When you’re soldering you should always use flux. 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.

What can be used instead of flux for soldering?

A: The classical fluxes were wood rosin and acid solutions – both intended to protect even etch the top surface when it gets hot and is likely to oxidize. Instead, you can place a puddle of solder on one (horizontal) surface, and with a pen knife blade, scratch the metal under the blob.

What can I use if I don’t have solder?

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.

Is silver solder stronger than regular solder?

Silver soldering, as used by jewelers, machinists and in some plumbing applications, requires the use of a torch or other high-temperature source, and is much stronger than soft soldering.

Do I need flux to solder?

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.
