Brazing Brass and Copper with Induction Heating


A client in the aerospace industry needed to braze brass and copper nozzles. They had been using a torch, but were looking for a cleaner and more repeatable heating solution. So they sent their parts into THE LAB at Ambrell for complimentary parts testing to see if induction might be a better heating solution for their brazing application. 

The LAB determined that an Ambrell EASYHEAT™ 6 kW, 150-400 kHz induction system with a custom-designed multiple-turn helical coil would be the right solution for this brazing application. The target part temperate was 1200 °F (649 °C).


The LAB used temperature indicating paint for testing, which dissolves when the part reaches temperature. It took about 120 seconds to heat the part to temperature. The speed and end-product met the client’s objectives.


There are numerous benefits to induction when compared to torch heating. Speed is often a benefit. Repeatability is also a key benefit, as induction can be easily automated and isn't dependent on operator skill. Finally, there's no open flame with induction, so it's a comparatively safer option that introduces less heat into the work environment. In the case of this client, repeatability and safety were the two primary benefits.
