Vacuum Brazing
Vacuum brazing joins metal parts in a vacuum furnace, using a filler metal that melts at a lower temperature than the base materials to create strong, clean, leak-proof bonds without oxidation, flux, or significant distortion
Vacuum brazing is one of the strongest bonding methods for joining, resulting in minimal distortion, leak-free joints, and clean and bright assemblies for customer shipments. We can join numerous materials including stainless steel, nickel alloys, molybdenum, carbon steel, and carbide.
