Brazing will happen under inert gas (argon). Ag4Wt% Ti,Cu8wt%Ti , and the eutectic Ag 26wt% Cu 4 wt % Ti are the active filler metal which are used , and the bonding phases at the filler metal / tantalum interface line almost contain ( Ti Ta Ta 0.49 O ) . Which means that active element ( titanium ) shares oxygen with tantalum to make this bond as a cheap filler .
