GH907 ndi mpweya wa Fe-Ni-Co womwe umaumitsa kutentha kwakukulu ndi kukulitsa kochepa komanso kupindika, kulimbikitsidwa ndi niobium, titaniyamu, silicon ndi trace boron. Aloyiyo imakhala ndi mphamvu zambiri, yocheperako yokulirakulira, kukana kutopa kotentha ndi kuzizira komanso pafupifupi modulus yokhazikika pansi pa 650 ° C. Malo a Curie ali pakati pa 400°C ndi 4000°C. Aloyiyo imakhala ndi coefficient yowonjezereka yotsika komanso kukana bwino kutopa kotentha ndi kuzizira. Malo a Curie ali pamtunda wa 400 ℃-450 ℃. Coefficient of expansion of alloy sichinasinthidwe pansi pa Curie point. Aloyi ndi oyenera kupanga mitundu yonse ya ndege ndi ndege mphete injini ndi magazini m'munsimu 650 ℃, ndipo mankhwala waukulu monga mipiringidzo, forgings, mbale ndi n'kupanga. Popeza aloyi alibe chromium ndi aluminiyamu zinthu, kutentha kwambiri makutidwe ndi okosijeni kukana ndi osauka. Mukagwiritsidwa ntchito kwa nthawi yaitali pamwamba pa 700 ° C, zotetezera zoyenera ziyenera kuikidwa. Pamwamba pa aloyi akhoza kuwomberedwa peened, amene bwino rotational kutopa ndi pafupifupi 18%.
