Quick Answer: What Is Silver Solder?

What metals can you silver solder?

Silver Solder can be used to join most common metals, including Mild Steel, Stainless Steel, Copper, Brass, Cast Iron and Dissimilar Metals..

What is the difference between 60 40 and 63 37 solder?

63/37 solder is made of 63% tin and 37% lead. It has a melting point of 183°C, slightly lower than the more common 60/40 blend. The primary advantage of this solder is not the lower melting point, but its eutectic property. … If a joint is moved during this stage, it can result in what is called a cold solder joint.

Can I silver solder stainless steel?

You can silver solder stainless to itself or to brass or copper to make easier connections without risk of corrosion problems. The joint will only be as strong as the silver solder itself. You can use any silver solder, but you will need an acid-based flux specifically manufactured for nickel or stainless steel.

Can I use Vaseline as flux?

Vaseline is an “oil” based grease, it has no flux properties. (It WILL do the opposite job of contaminating your joint.) … The trick with flux is not the “feel”, > smell, or taste, but the ability to carry heat.

Can you use silver solder on copper?

A simple way of soldering together a piece of copper and a piece of silver is to use a technique called sweat soldering. … Now, with a small amount of easy silver solder coated in flux and placed at the very end of some fine tweezers, you can begin to heat it with your hand torch.

What is the difference between silver solder and regular solder?

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.

Can you solder silver with a soldering iron?

CAN I SOLDER STERLING 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.

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.

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 silver jewelry be repaired?

Most jewelry stores will not even touch silver jewelry. If a repair on sterling silver jewelry can be done, I can do it, however, difficulties with repairing sterling jewelry include a risk to the stones, heat transfer when soldering silver, and Rhodium plating.

Can you silver solder aluminum?

Just because a flux is strong enough to solder an alloy like stainless steel doesn’t mean it’ll work on aluminum. … Certain filler alloy combinations, such as tin-zinc, tin-silver, SN100C ™ and ALUSAC-35™ are better at creating this special bond.

Is silver solder real silver?

Silver Solder. … These are primarily tin, with only traces (maybe 5 percent) of silver and other components. In essence, they are high performance substitues for lead solder (lead solder should never be used on silver items). They are often called silver tin solders, but in some cases are referred to as silver solders.

What is silver solder made of?

Generally, silver solder contains: 65% fine silver. 20% copper. 15% zinc.

Do you need flux to 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.

Can you 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.

What is the difference between easy medium and hard silver solder?

Easy has a melt temperature of 1235 F and a flow temperature of 1325 F. Medium has a melt temperature of 1265 F and a flow temperature of 1390 F. Hard has a melt temperature of 1330 F and a flow temperature of 1475 F.

What is silver solder used for?

Brazing solders are formulated primarily for strength, silver solder is used by jewelers to protect the precious metal and by machinists and refrigeration technicians for its tensile strength but lower melting temperature than brazing, and the primary benefit of soft solder is the low temperature used (to prevent heat …
