Vacuum brazing is a welding process in which a group of welding parts are heated to the temperature above the melting point of the filler metal but lower than the melting point of the base metal under the vacuum condition, and the wetting and activity of the filler metal to the base metal constitute the welding seam (brazing temperature varies with different data).

Vacuum furnace A furnace with electrically heated elements that surround the workload and heat the brazing filler metal to the liquidus state so flow and capillary attraction are achieved. To permit brazing of alloys that are sensitive to oxidation at high temperatures, a pumping system is employed that removes oxygen.
products: Vacuum Furnaces: EGB offers a range of conventional design high vacuum furnaces, for small and medium batch processing, with hot zone dimensions up to 1 metre. Precise specification is determined with the customer; our designs are flexible, allowing wide choice of maximum temperature and vacuum levels.
Why Vacuum Furnace Brazing? Vacuum brazing is usually a high temperature (typically 1700 °F/927 °C - 2250 °F/1232 °C), fluxless process using nickel-base, pure copper and less frequently precious BFM. There are several advantages to brazing under vacuum conditions: • The purity level of the atmosphere (vacuum) can be
Ideal for brazing and heat treating processes that require high part quality and heating consistency, these induction furnaces heat parts of virtually any shape in a high temperature, high vacuum environment or in partial pressure of an inert gas.
Your new furnace is designed, built, and shipped from our Denver Colorado manufacturing center. This allows us to bring our 50 years of experience to every stage of the process. We focus on quality control at each step to ensure that your furnace system meets our standards and your expectations.
Gold brazing is often used with high-temperature alloy and stainless steel assemblies. Gold brazing can be performed in both vacuum and atmospheric furnaces. Gold brazing performed in a vacuum furnace is very efficient because it does not use flux and does not require post-braze cleaning. Our gold brazing services are NADCAP accredited.
