Brazing is a metal-joining process that uses heat to join two or more pieces of metal together. It is often used as an alternative to welding when welding is not possible or practical due to the material’s physical characteristics. But what exactly is the filler metal used during brazing?
The filler metal used in brazing is an alloy of copper and zinc. This copper-zinc alloy, known as brass, melts around 900-950°F (480-510°C). When heated to its melting point, brass flows into the gap between two pieces of metal that need to be joined, creating a strong bond between them. In addition to brass alloys, some brazing filler metals are also made with silver or nickel for special applications.
When it comes to selecting a filler metal for brazing, several factors need to be considered. These include the materials being joined, joint design and clearance, application temperatures and environmental conditions, cost considerations, corrosion resistance, and strength requirements. The type of filler metal chosen should match all these requirements to ensure a successful joint.
Brazing has many advantages over other forms of joining metals together, such as welding and soldering, because it can join dissimilar metals without damaging or weakening them; it requires no high pressure; it can be done quickly; and it provides a clean finish with minimal surface distortion. It’s no wonder why brazing has become such a popular method for joining metals together!
Conclusion:
In conclusion, if you’re looking for a reliable way to combine two pieces of metal, consider brazing! The filler metal used in this process—an alloy of copper and zinc—is easy to work with and provides strong bonds between materials that last for years. Plus, this method is comparatively inexpensive compared to other methods, such as welding, which makes it ideal for those looking for an economical solution when joining metals together. So don’t hesitate—brazing could be the perfect answer when your project calls for joining two pieces of metal together!
