Incoloy Alloy Nickel 907 Piping
INCOLOY alloy 907 (UNS N19907) is a nickel-iron-cobalt alloy having high strength along with a low coefficient of thermal expansion. The alloy is strengthened by age-hardening heat treatments.

INCOLOY alloy 907 contains no chromium because the presence of that element would increase thermal expansion. The absence of chromium, however, makes the alloy more susceptible to oxidation in high-temperature atmospheres. In some applications, INCOLOY alloy 907 may require a protective coating to prevent excessive oxidation. Figure 3 compares INCOLOY alloy 907 with INCONEL® alloy 718 (19% chromium) in a cyclic oxidation test at 1200°F (650°C).
The combination of low expansion and high strength makes INCOLOY alloy 907 useful for gas-turbine components. The low expansion enables closer control of clearances and tolerances for greater fuel efficiency. The high strength makes possible higher strength-to-density ratios for lower weight in aircraft engines. For those reasons, INCOLOY alloy 907 is used for gas-turbine seals, shafts, casings, and other structural parts.
