Brazing of Titanium and Titanium Alloys
Titanium Brazing
Several brazing techniques are applicable to titanium. These include induction brazing, resistance brazing and furnace brazing in an argon atmosphere or in vacuum. Torch brazing is not applicable to titanium.
Since brazing techniques have the potential for contaminating titanium surfaces, cleanliness is important and consideration should be given to argon or helium gas shielding.
Alloys for brazing titanium to itself or other metals are titanium-base (70Ti-15Cu-15Ni), silver-base (various), or aluminum-base (various). The titanium-base alloy requires temperatures in the vicinity of 1700 degrees F., whereas the silver and aluminum-base alloys require 1650 degrees F. and 1100- 1250 degrees F. respectively. If corrosion resistance is important, tests should be run on brazed joints in the intended environment prior to use. TIMET's research lab is available for consultation on titanium's corrosion resistance in your environment. The titanium-base alloy reportedly offers superior resistance to atmospheric corrosion and saline environments.
