GH907 ke pula ea Fe-Ni-Co e thatafatsang mocheso o phahameng oa motsoako o nang le katoloso e tlase le deformation, e matlafalitsoeng ka niobium, titanium, silicon le trace boron. Alloy e na le matla a phahameng, coefficient e tlase ea ho atolosa, ho hanyetsa hantle mokhathala o chesang le o batang le modulus e batlang e sa fetohe ea elasticity ka tlase ho 650 ° C. Sebaka sa Curie se pakeng tsa 400°C le 4000°C. Alloy e na le coefficient e tlase ea ho atolosa le ho hanyetsa hantle mokhathala o chesang le o batang. Sebaka sa Curie se maemong a 400 ℃-450 ℃. Coefficient ea katoloso ea alloy ha e le hantle ha e fetohe ka tlase ho ntlha ea Curie. Alloy e loketse bakeng sa tlhahiso ea mefuta eohle ea mehele ea enjene ea sefofane le limakasine tse ka tlase ho 650 ℃, 'me lihlahisoa tse ka sehloohong li kenyelletsa mekoallo, forgings, lipoleiti le lihlopha. Kaha motsoako ha o na likarolo tsa chromium le aluminium, ho hanyetsa mocheso o phahameng oa oxidation ho fokola. Ha e sebelisoa nako e telele ka holimo ho 700 ° C, ho lokela ho sebelisoa litlolo tse sireletsang tse loketseng. Bokaholimo ba motsoako bo ka thunngoa, e leng ho ntlafatsang mokhathala o potolohang ka 18%.
