GH99 ni Ni-Cr ishingiye ku mvura igabanya ubukana bwo hejuru cyane, ishobora gukoreshwa igihe kirekire munsi ya 900 ° C, kandi ubushyuhe bwa serivisi bwigihe gito bushobora kugera kuri 1000 ° C. GH99 alloy ishimangirwa no kongeramo chromium, cobalt, tungsten na molybdenum kugirango igisubizo gikemuke, hiyongereyeho aluminium na titanium kugirango habeho ibyiciro bikomeza gusaza, no kongeramo boron, cerium na magnesium kugirango bisukure kandi bishimangire imbibi z’ingano. GH99 alloy ifite imbaraga nyinshi zumuriro, itunganijwe neza, kandi ifite imashini ishushe kandi ikonje ikora no gusudira.GH99 irakwiriye gukora ibyumba byo gutwika moteri ya aero-moteri hamwe n’ibyumba byo gutwika amavuta hamwe n’ibindi bikoresho byo mu rwego rwo hejuru byo gusudira. Ibicuruzwa nyamukuru bya GH99 ni utubari dushyushye, amasahani, insinga no kwibagirwa. Hamwe n'umusemburo wakozwe nuburyo bunini bwa plaque, urashobora gukoreshwa neza nyuma yumuti ukomeye Kuvura nta gusaza Umuti. Amavuta ya 700 ℃ ~ 950 aging gusaza igihe kirekire ntabwo yabonye ibyiciro byangiza.

Amavuta yakoreshejwe mugukora aero-moteri itunganya nozzle shell, ingunguru yingufu nibindi bice; umurongo uzungurutse wakoreshejwe mugukora ibyuma bya compressor ya aero-moteri; ibihimbano byakoreshejwe mugukora turbine nini zo mu mazi hamwe na misile zo mu bwoko bwa misile.
