Sehlahisoa SEHLOOHO
GH907 ke pula ea Fe-Ni-Co e thatafatsang katoloso e tlase ea mocheso o phahameng alloy, e matlafalitsoeng ka niobium, titanium, silicon le trace boron. Alloy e na le matla a phahameng, coefficient e tlase ea katoloso, ho hanyetsa hantle mokhathala o chesang le o batang le modulus e batlang e sa fetohe ea elasticity ka tlase ho 650 ℃. Sebaka sa Curie se pakeng tsa 400 ℃ le 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. Hobane motsoako ha o na chromium, likarolo tsa aluminium, ho hanyetsa oxidation ea mocheso o phahameng ho fokola. Ha e sebelisoa nako e telele ka holimo ho 700 ℃, ho lokela ho amoheloa litlolo tse sireletsang tse loketseng. Bokaholimo ba motsoako bo ka phunyeletsoa, 'me mokhathala o pota-potileng o ka eketseha ka hoo e ka bang 18% ka mor'a ho phunya.
