Incoloy 907 is a nickel-iron alloy renowned for its high strength and low thermal expansion coefficient. This material undergoes strengthening through aging hardening heat treatment. The perfect balance of low thermal expansion and high strength makes Incoloy 907 ideal for gas turbine components. Its low thermal expansion allows precise control of clearance and tolerances, significantly improving fuel efficiency. The high strength enables higher strength-to-density ratios in aircraft engines, effectively reducing overall weight. For these advantages, Incoloy 907 is widely used in gas turbine sealing systems, shafts, casings, and other critical structural components.
The properties of Incoloy 907 alloy are attractive for other applications, including instrumentation, glass metal seals: ceramic molds and power generation.
The density of the alloy is ρ=8.33g/cm³.
