Claims
- 1. A filler metal alloy for welding cast nickel aluminide alloys consisting essentially of from about 15 to about 17 wt. % chromium, from about 4 to about 5 wt. % aluminum, equal to or less than about 1.5 wt. % molybdenum, from about 1 to about 4.5 wt. % zirconium, greater than zero to about 0.01 wt. % yttrium and the balance being nickel.
- 2. A filler metal alloy in accordance with claim 1 wherein said chromium is about 16 wt. % to about 17 wt. %, said molybdenum is about 1 wt. % to about 1.5 wt. % and said zirconium is about 1 wt. % to about 2 wt. %.
