Brazing ovens operate at various temperatures depending on the materials being brazed and the specific application.
Brazing typically requires higher temperatures than soldering.
5 Key Temperatures You Should Know
1. Reducing Atmosphere Furnace Brazing
For reducing atmosphere furnace brazing, where copper or copper-base alloys are used as filler materials, the brazing temperature is usually over 1085°C (1985°F).
2. Vacuum Brazing
In vacuum brazing, especially when stainless steels are involved, the temperatures are usually above 1000°C (1832°F).
This range allows for heat treatments as part of the brazing process.
3. High-Temperature Nickel Alloys
When brazing high-temperature nickel alloys, the temperature is typically between 1040-1200°C (1900-2200°F) in a vacuum level of 10-4 to 10-5 mbar (10-4 to 10-5 Torr).
After brazing, the work is allowed to slow cool to approximately 980°C (1800°F) for solidification of the filler metal.
4. Hydrogen Brazing
When brazing with hydrogen, the atmosphere within the furnace should be slightly positive.
The optimal temperature for copper brazing is usually between 1100 and 1500°F.
5. General Considerations
It's important to note that the specific temperature and time requirements for brazing may vary depending on the materials, joint design, and desired properties of the finished product.
