What Are Brazing Rods Used For? will be the topic of this article.
As we all know, brazing is a technique to join two pieces of metal together by using a filler metal.
This filler metal comes in the form of a brazing rod.
The filler rod is melted and then used to create a strong joint between the two metal pieces once it cools back down.
We have been looking at different metal forming techniques lately, one of which being the incredible process known as brazing.
We have briefly scratched the surface of what this technique has to offer, and today we will dig in a little bit deeper by looking at brazing rods!
What are brazing rods, and what are they used for? In this article, we will answer those and many more questions on the topic of brazing rods.
After reading you will be a true expert on brazing rods, so without further ado, let’s get started!
What Are Brazing Rods Made Of?
When we talk about brazing rods lots of questions immediately spring to our minds.
One such question has to do with the material that brazing rods are made of as this plays an important role in the brazing process.
That’s why we will now take a look at the question, what are brazing rods made of? Let’s take a closer look at this interesting question!
The answer to this question isn’t actually as straightforward as you might expect it to be, there is no such thing as a universal brazing rod.
What material of brazing rod you use is very much dependant on the two metal types that you are trying to join together, and therefore the situation often changes.
Generally speaking, however, we use a mixture of roughly 60% copper and 40% zinc to form a universal brazing rod to be used for basic brazing jobs!
How To Use Brazing Rods?
Now that we have learned a little bit more about brazing rods and the specific materials that they are made of it is time to jump from one question to the other, as there are still many questions left unanswered surrounding brazing rods.
One such question lies in how they use the brazing rods. So, let’s take a look at how to use them!
We should start by heating the two metal surfaces that we are trying to join until the metal’s surface is glowing hot.
When this is the case it is time to apply the brazing rod in between the two metal pieces, all while heating the rod using your heat source.
You should now be able to press the metal pieces together to form a joint with the brazing rod. It is that easy, now let it cool and enjoy your two joined pieces of metal!
What Is The Strongest Brazing Rod?
We now know a lot more about brazing rods and how to use them.
We have briefly touched on the fact that there are multiple types of brazing rods made from different materials, and this of course leads to many questions.
One such question has to do with strength, as that is inevitably what we are looking for when brazing! So, let’s take a closer look at the strongest brazing rod!
Let’s jump straight into the answer, as the strongest brazing rod we use is a brazing rod known as HTS-528.
This is a stainless-steel brazing rod that can be used to join large pieces of cast iron and other heavy metals.
It has an incredibly high tensile strength, and it can only be used at seriously high temperatures. This is the best brazing rod for robust joints between metal pieces!
What Temperature Does Brazing Rod Melt?
We have now learned many things about brazing rods and how to use them, they are great for many things and brazing rods are one of the main things that allow the incredible technique of brazing to be possible.
We have answered many questions surrounding the topic, but some important matters are still left unanswered.
One such question has to do with the temperature the rods melt at. So, let’s take a look at what temperature a brazing rod melts!
The answer to this question of course depends on the type of brazing rod you’re using, different materials have different melting points after all.
Generally speaking, the melting point of a brazing rod will be around 875℃ or around 1600℉! That’s why you should always be careful when brazing, as the temperatures can get seriously high.
How Do You Use Aluminum Brazing Rods?
We have briefly looked at how to use the regular brazing rods and we have seen how the brazing process works.
However, we have not yet looked at the different brazing rods and how they are used in this process.
Let’s take a look at aluminum brazing rods, how do we use them, and is it any different from regular rods? Let’s find out!
Brazing with aluminum rods follows the same principles as regular brazing, but there are a few tricky elements to look out for.
You should heat the metal pieces and not the rod itself, and when working with aluminum it is important to work with proper equipment such as a quality torch.
If you follow these precautions, you should be golden!
Brazing As A Hobby And My Personal Preference
Many people think of brazing as being a strictly industrial process, but it is actually incredibly popular among hobbyists like myself, and perhaps you reading this!
It is an incredibly fun activity that can yield many great results, but where can you get brazing rods and which ones do I use?
You can get brazing rods at pretty much any local hardware and there are many options both in material and size.
I personally use low fuming copper brazing rods of diameters varying between 1/16” and 3/32”, however, some of this is a personal preference.
If you are looking to get into brazing there are many great resources to be found on YouTube and on the internet!
Final Thoughts On… What Are Brazing Rods Used For?
All in all, brazing is a beautiful process with many real-world applications and a brazing rod forms the center of this process.
We have looked at everything surrounding brazing rods and you can now call yourself an expert in this field! Thank you for reading and good luck on your brazing journey!
Frequently Asked Questions
Let’s finish off by looking at some frequently asked questions surrounding brazing rods!
What is the best brazing rod for cast iron?
The best brazing rod for cast iron is the incredibly strong HTS-528 rod!
Will the brazing rod stick to Aluminum?
Yes, it will, you can even use Aluminum brazing rods for ultimate results.
What type of rod is used for brazing steel?
The 31T rod is great for brazing steel, any other rod with flux will work too.
What brazing rod to use for brass?
When working with brass a copper, zinc alloy brazing rod is the way to go.
What brazing rod to use for copper?
When brazing copper you should look for non-consumable electrode brazing rods.
