Tin solders are useful materials for quite a few different practices including roofing. They are fairly simple in concept, but can be applied to so many different projects and materials that they have made themselves essential to various professions. Some people in the industry rely on solder so much that they always maintain a supply on hand for any project that might come up and benefit from soldering. In case you are unfamiliar with this material and need a quick run-down to help you figure out what type of solder bar you need, we have some details you really need to know. These are the most basic, fundamental facts about solder bars that you should know before working with or purchasing any.
Let’s start off describing what a solder bar is exactly before we move on to listing the particular types you can work with. A solder bar is a metal alloy set in the shape of a bar for convenient use. A key feature of it is that it has a low melting point, which allows you to melt it down easily when you need to manipulate it. They are comprised of tin and another substance such as lead or flux, which we will discuss below, giving them the properties they have. The low melting point makes a difference because solder bars are used to act as a bonding agent, melting down and hardening again to connect to separate components.
What They Are Used For
Solder bars are used in various industries including electronics, plumbing, and roofing because of their versatile abilities to fuse metals. The concept is fairly simple: the worker heats up the solder bars and uses that metal to act as a glue between other metal parts that they want to connect. Once the solder cools and hardens again, the bond is formed and those formerly separate components become one piece. This comes in handy when roofing because the bond is fantastic at creating strong holds where leaks will not come through. If you are considering using your solder bars for roofing, you will definitely find it useful when working around flashings or seams in particular. A solder bar is easy to carry and heat up while on a job site, making it an impressively convenient material to have on hand. It is incredibly practical, performs well, and is easy to work with.
Lead-Based Solder
Now that we have spent some time discussing solder bars in general, let’s take a moment to quickly go over the two main groups of solder bars that you can choose between, based on your needs and preferences. The first type of solder bar we will discuss is the lead-based solder, which is also the more traditional type to see. It is made from a blend of tin and lead which is normally either a 50/50 ratio or 60/40, respectively. This type of solder bar is less common these days because of the lead content, but it can still be found in use today, especially in the roofing industry. It is valued for being affordable and fairly easy to work with.
Lead-Free Solder
The alternative type of solder bar is the lead-free variety which is largely made of tin, but can include another substance such as copper to round it out. This solder is known for being a little more difficult to work with, but becomes easier as you come to understand the material. It is mainly valued for being a safer material for professionals to work with because of the absence of lead. It is a great material overall and is becoming increasingly common across industries.
