GH99 o le Ni-Cr faʻavae faʻamaʻaina faʻamaʻaʻaina faʻafefete maualuga vevela, lea e mafai ona faʻaaogaina mo se taimi umi i lalo ole 900 ° C, ma o le taimi puʻupuʻu maualuga maualuga e mafai ona oʻo i le 1000 ° C. GH99 uʻamea e faʻamalosia e ala i le faʻaopopoina o le chromium, cobalt, tungsten ma le molybdenum mo le faʻamalosia o vaifofo malosi, alumini ma le titanium e fausia ai vaega faʻamalosia matua, ma le boron, cerium ma le magnesium e faʻamamā ma faʻamalosia ai le saito. GH99 uʻamea e maualuga le malosi o le vevela, faʻamautuina faʻalapotopotoga, ma faʻamalieina le vevela ma le malulu o le faʻatulagaina ma le faʻaogaina o le faʻagasologa o le faʻatinoga. GH99 e talafeagai mo le gaosiga o potu faʻafefeteina aero-engine ma potu faʻafefe suauʻu ma isi vaega faʻapipiʻi maualuga maualuga. Faatasi ai ma le uʻamea gaosia e le fausaga ipu tele, e mafai ona faʻaoga saʻo pe a maeʻa le vaifofo malosi Togafitiga e aunoa ma le matua Togafitiga. E leʻi maua le uʻamea e iai ni vaega faʻaleagaina pe a uma le matua umi i le 700 ℃ ~ 950 ℃.
