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. Gold, copper, nickel, cobalt, titanium and ceramic based filler metals are successfully vacuum brazed.
