Even though brazing is popularly used for metals, it is also used for ceramics occasionally. Using the right rod makes all the difference when it comes to brazing, which is a widely used joining method in many industries. The brazing rod is used as a filler between individual parts of metal and is melted to form a joint.
It is different from welding as the melting temperatures are comparatively low but still higher than that of the soldering process. Since a brazing rod is what brings together the process, it is crucial to choose one that is appropriate. And there are some key factors that buyers should consider for a seamless experience.
The Right Material
When buying brazing rods, buyers will come across many materials, including aluminum, stainless steel, copper and copper phosphorous, brass, nickel, bronze, and more. All materials are suited for different purposes, but copper and brass are considered the best in terms of quality. Although it majorly depends on the metals being used, copper and brass have good resistance to overtime wear and tear and easily work with more metal types. On the other hand, nickel is also an excellent choice for regular use items and gives an added shine. Even bronze brazing rods have good mechanical and physical properties and are robust.
Size and Temperature
All brazing rods vary in size, and this is something a buyer needs to determine based on other metal alloys being used for the process. The rod’s dimensions have to be proportionate to the pieces being joined for a good look and finish. And there is a myriad of sizes that buyers can choose from. The next factor is the brazing rod’s temperature, which again depends on the substance being used. Whether you require high or low melting points, the brazing rod should be chosen accordingly as all have different working temperatures.
Flux or No Flux?
The presence of flux plays a vital role in the brazing process as it is a protective coating from the atmosphere temperature. While some rods are self-fluxing or already flux-coated, some come with flux separately in a tube. But flux is required only for certain alloys like aluminum and magnesium, and not all. A few brazing rods do not require an additional flux coating, but it ultimately depends on the metal being used in the brazing process.
