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.
They burn much hotter than ordinary torches, which makes silver soldering go faster and easier.
Use silver solder like ordinary solder..
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).
Does solder stick to aluminum?
Aluminum needs heat to accept solder, usually to the tune of 300°C or more. … Aluminum is a great heat sink, so the heat source will need to be even higher to get the aluminum up to the right temperature. Soldering aluminum is not like soldering copper; it’s not enough to just heat up and melt the solder.
What temperature does 50/50 solder melt at?
Melting Range: 361° – 421° F (solid to liquid) Shear Strength: 5200 psi. Tensile Strength: 6000 psi.
What temperature is best for soldering?
If you are having trouble getting the solder to melt, it means you should turn up the heat a bit. If you are burning your components, it might be time to consider turning the temperature down. I usually solder with a temperature between 350 degrees Celsius and 400 degrees Celsius (660 to 750 Fahrenheit).
Does solder get old?
Flux cored solder wire has a limited shelf life determined by the alloy used in the wire. For alloys containing more than 70% lead, the shelf life is two years from date of manufacture. Other alloys have a shelf life of three years from date of manufacture.
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.
Can you solder instead of Weld?
Of course you can, and if the prep work is done correctly you will have a good bond between the metals. In some cases the two metals can not be welded, solder is the only option. It is preferred to weld metals since that is a blending of the two metals as compared to bonding them together as soldering will do.
Can you use solder to weld steel?
You can even use solder to join copper or brass to stainless steel, you just need the proper flux. … If you must use a paste flux, use it sparingly. Use plumbing (silver) solder only. Do not use electrical or jeweler’s solder because these often contain lead or cadmium.
Why is my solder not shiny?
The flux is important in cleaning the surface you are putting solder to and is activated by heat. If it gets all burnt-up on the iron, you will notice the solder not look as shiny and smooth the more it gets burnt away.
Can plumbing solder go bad?
How much time, well typically the expiration date stamped on the label gives you about 2-3 years from the date of manufacture, not purchase. After that date, and depending on the lead content, the flux will begin to react with the lead and eventually get to the point where it won’t work effectively.
Can solder joints go bad?
The only way a joint can fail is if it is not made properly, whether it is because the solder did not flow properly or the pipe was not inserted all the way into a fitting. It has nothing to do with turbulence because the solder does not interact with the liquid flow.
Does silver solder paste go bad?
The shelf life of the solder paste is established by the Manufacturer based on their internal studies. The expiration date should be either on the label or the paperwork that came with the shipment. Depending on vendor, the most likely shelf life will be 3 or 6 months at room temperature.
Is silver solder stronger than 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.
At what temperature does 60 40 solder melt?
around 190°C60/40 solder is made of 60% tin and 40% lead. It has a melting point of around 190°C, depending on the exact composition. Iron tip temperatures of at least 300°C are recommended.
What temperature will solder melt?
Soft solder typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K), and is commonly used in electronics, plumbing, and sheet metal work. Alloys that melt between 180 and 190 °C (360 and 370 °F; 450 and 460 K) are the most commonly used.
Why is solder so expensive?
Small diameter solder always costs more forma given weight. Unfortunately with modern components you need to buy very small diameter solder for hand soldering. Yes, as the diameter decreases the price definitely increase.
What is the hardest solder?
As I said before, the tin/silver solders are BY FAR the hardest and strongest of the so-called “soft” solders (i.e. with reasonable melting temps and not a melting temp of 900 F–that’s a “hard” solder, and is really probably better classed as brazing and not soldering).
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.
What is the best solder?

Do I need flux to solder?
When soldering circuit boards, or other electrical / electronic devices, yes – you need to use flux. Fortunately, almost all solder for electronics use has an internal core of flux, so you usually don’t need to add more.
