Incoloy 907 (UNS N19907)
Category: INCOLOY
Overview
INCOLOY 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.
The combination of low expansion and high strength makes INCOLOY alloy 907 useful for gasturbine 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.
