GH907 wani hazo ne na Fe-Ni-Co yana taurare ƙananan nakasar nakasar babban zafin jiki, ƙarfafawa da niobium, titanium, silicon da boron. The gami yana da babban ƙarfi, low coefficient na fadada, mai kyau jure zafi da sanyi gajiya da kusan m modulus na elasticity kasa 650 ℃. Matsayin Curie yana tsakanin 400 ℃ da 450 ℃. Ƙididdiga na faɗaɗa gami da gaske baya canzawa a ƙasan ma'anar Curie. The gami dace da samar da kowane irin jirgin sama da Aerospace engine zobe da mujallu a kasa 650 ℃, da kuma manyan kayayyakin sun hada da sanduna, forgings, faranti da tube. Saboda gami ba ya ƙunshi chromium, abubuwan aluminum, juriya na iskar shaka mai zafi ba shi da kyau. Lokacin amfani da dogon lokaci sama da 700 ℃, ya kamata a yi amfani da kayan kariya masu dacewa. Za a iya harbi saman gami da peened, da jujjuya gajiyar lankwasawa za a iya ƙara da kusan 18% bayan harbi peening.
