Incoloy 907 / UNS N19907

INCOLOY® alloy 907 (UNS N19907) is a nickel-ironcobalt alloy having high strength along with a low
coefficient of thermal expansion. The alloy isstrengthened by age-hardening heat treatments

Product Description:

Incoloy 907 is a Fe-Ni-Co based precipitation-hardened low expansion deformation superalloy, which is comprehensively strengthened by adding niobium, titanium, silicon and trace boron elements. The alloy has high strength below 650℃, low coefficient of expansion, good resistance to thermal and cold fatigue and almost constant elastic modulus. The Curie point is between 400℃ and 450℃. The expansion coefficient of the alloys below the Curie point is basically unchanged. Suitable for the production of various types of aviation and aerospace engine rings and casings below 650℃, the main products are bars, forgings, plates and strips.
