The design of a new Ti-Zr-Cu-Ni-Ag brazing filler metal for brazing of titanium alloys

Titanium alloys with light weight and high strength at 300–400 °C have been widely used in aerospace industry. Vacuum brazing technique with the advantage of low stress and high efficiency for Ti-based alloy has been developed for manufacturing the components in complicated structure such as heat exchanger. The newly designed filler material as Ti-12.5Zr-13.7Cu-11.6Ni-2.2Ag wt% was used for brazing the dissimilar joint of CP-Ti (as TA2) and...
