 6.Description 

   A nickel-chromium alloy similar to NIMONIC alloy 75 but made precipitation hardenable by additions of aluminum and titanium.

The alloy has good corrosion and oxidation resistance and high tensile and creep-rupture properties at temperatures to 1500°F (815°C).

Used for gasturbine components (blades, rings, and discs), bolts, tube supports in nuclear steam generators, die-casting inserts and cores,

and exhaust valves in internal-combustion engines.
