GH907 bụ oke mmiri ozuzo Fe-Ni-Co na-eme ka mgbasa mgbasawanye dị ala dị elu, jiri niobium, titanium, silicon na trace boron sie ike. Alloy nwere ike dị elu, ọnụ ọgụgụ dị ala nke mgbasawanye, ezigbo iguzogide ike ọgwụgwụ na-ekpo ọkụ na oyi na ihe fọrọ nke nta ka ọ bụrụ modul nke elasticity n'okpuru 650 ℃. Ebe Curie dị n'etiti 400 ℃ na 450 ℃. Ọnụọgụ nke mgbasawanye nke alloy agbanwebeghị n'okpuru ebe Curie. Alloy kwesịrị ekwesị maka mmepụta nke ụdị ụgbọ elu na ikuku engine yiri mgbaaka na magazin n'okpuru 650 ℃, na isi ngwaahịa na-agụnye mmanya, forgings, efere na ibe. N'ihi na alloy enweghị chromium, aluminom ọcha, elu okpomọkụ oxidation iguzogide adịghị mma. Mgbe a na-eji ogologo oge karịa 700 ℃, ekwesịrị ịnakwere mkpuchi mkpuchi kwesịrị ekwesị. E nwere ike gbaa elu nke alloy peened, na ike ọgwụgwụ na-ehulata nwere ike ịbawanye site na 18% mgbe agbachara peening.
