Brazing options don't just stop after Vacuum and Aluminum Dip. See what other brazing services Thermal-Vac has to offer for your jobs that require that certain touch.


Hydrogen Brazing

  • Eliminates the need for fluxes to protect braze joint surfaces from oxidation
  • Oxides on parts which are heated to braze temperature tend to dissociate, and are subsequently flushed from the retort with the positive flow of hydrogen; parts emerge from the retort looking bright and clean
  • Allows for precise control of the entire brazing cycle
  • Ensures an exacting braze joint temperature with the aid of imbedded or attached thermocouples
  • Thermal-Vac typically uses copper braze filler metal in hydrogen for brazing stainless or carbon steel assemblies.

 torch-brazingTorch Brazing

  • Perfectly suited for smaller production volumes or unusual designs
  • Employs a torch to heat the joint and melt the filler material
  • The joint is protected from oxidation by using filler materials that melt well below the oxidizing temperatures of the parent materials
  • Versatile technique which produce consistently high-quality connections
  • With the exception of a few metals such as titanium, zirconium and certain stainless steels, most can be torch brazed

induction-brazingInduction Brazing

  • Heats electrically conductive parts in an electromagnetic field produced by alternating current flow in an induction coil
  • Heat assemblies at the surface or to various depth by selecting an appropriate frequency and power density
  • Heating can be localized to minimize metallurgical changes in the assembly and reduce distortion
  • Can be conducted in air with minimum discoloration
  • Thermal-Vac commonly joins carbon alloy and stainless steels, copper alloys, and nickel alloys





Ferocious temperatures, extreme environments, and exacting tolerances make aerospace applications incredibly difficult, though this is precisely where we excel.
