What Is Plumbing Solder Made Of?
You’ve probably wondered: what is plumbing solder made of? After all, it looks like a thick wire. But when soldering electronics, it’s made of a thinner wire – as thin as 0.064 inch. This difference can lead to a few complications – such as damaging electronics. Plus, it can lead to code and legal problems if you accidentally solder the wrong way. But don’t worry: there are ways to avoid any of these pitfalls. what is plumbing solder made of
When choosing plumbing solder, it’s important to know exactly what’s in it. The basic chemical makeup of plumbing solder is lead, copper, and tin. Lead promotes corrosion while tin protects itself by forming an insoluble oxide. Lead is toxic at even small amounts, so plumbing solders started to contain less lead. As lead was found to be dangerous to human health, it was replaced in plumbing solder with silver or antimony. Copper was also sometimes added to plumbing solder, but the proportion of tin was increased.
While plumbers use thick bars of plumbing solder, jewelers use thin sheets of it. They apply flux separately to the solder, and then solder the pieces together. The difference between the two types of solder lies in their melting points. Plumbers apply plumbing-suitable solder, while jewelers use rosin-core solder for electrical connections. Rosin-core solder readily melts in the heat of the soldering iron and avoids damaging electrical components.
Copper pipes carrying drinking water are recommended to be soldered with lead-free solder. The latter contains an alloy without lead, usually tin or another metal. In addition to the composition of plumbing solder, there is also a flux material. Copper, nickel, and rosin-core wires do not contain flux material, while solid-core copper pipes do. Those who use lead-free solders are safer for drinking water pipes, but they should still be avoided for electrical applications.
As for the materials used, Canfield and Alderwood solders are the most commonly used ones. Both have melting temperatures between 415 and 455 degrees Fahrenheit. While Canfield is best for copper pipes, they are not suitable for aluminum and brass. Luckily, they are both effective for plumbing. If you are not sure about what plumbing solder is made of, don’t worry! There are many options available in the market.
Solder is used in the construction industry to connect metals to one another. The main difference between them is that acid core solder is made from a wire core filled with an acid-based flux. This solder is more resistant and prevents the formation of metal oxides or weak joints. It must be cleaned after the soldering process. The latter is mostly used in plumbing applications, where it is used to join sheet metal pipes.
If you’re wondering what plumbing solder is made of, it can be a bit tricky to tell the difference between it and electrical solder. The difference is that lead-free plumbing solder can be used in older homes and buildings. It contains tin and bismuth and is much more difficult to see in the finished product. But if you have a plumbing problem, you should consider switching to lead-free solder.
