GH907 yog Fe-Ni-Co nag lossis daus hardening tsawg expansion deformation siab kub alloy, ntxiv dag zog rau niobium, titanium, silicon thiab kab boron. Cov hlau muaj lub zog siab, qis coefficient ntawm kev nthuav dav, zoo ua haujlwm rau kub thiab txias qaug zog thiab yuav luag tas li modulus ntawm elasticity hauv qab 650 ℃. Curie point yog nruab nrab ntawm 400 ℃ thiab 450 ℃. Lub coefficient ntawm expansion ntawm alloy yog qhov tseem ceeb tsis hloov hauv qab Curie point. Cov hlau yog tsim rau kev tsim txhua yam ntawm aviation thiab aerospace cav rings thiab cov ntawv xov xwm hauv qab 650 ℃, thiab cov khoom tseem ceeb muaj xws li tuav, forgings, daim hlau thiab strips. Vim tias cov hlau tsis muaj chromium, txhuas cov ntsiab lus, kub oxidation kuj tsis zoo. Thaum siv lub sijhawm ntev tshaj 700 ℃, cov txheej txheem tiv thaiv tsim nyog yuav tsum tau txais yuav. Qhov saum npoo ntawm cov hlau tuaj yeem raug tua peened, thiab kev sib hloov kho qhov qaug zog tuaj yeem nce li ntawm 18% tom qab txhaj tshuaj peening.

Cov alloy tau siv nyob rau hauv qhov zoo hauv kev tsim cov aero-engine high-pressor compressor rear magazines, load-bearing rings, heat-insulating rings, combustion chamber sealing rings, honeycomb seats and turbine rings.
