Waspaloy ni nikel ishingiro yimyaka nikomakomeye ya superalloy hamwe nubushyuhe buhebuje bwo hejuru hamwe no kurwanya ruswa, cyane cyane kuri okiside, ku bushyuhe bwa serivisi bugera kuri 1200 ° F (650 ° C) kugirango bikoreshwe cyane, kandi bigera kuri 1600 ° F (870 ° C) ) kubindi, bidasabwa bike, gusaba.Imbaraga zubushyuhe bwo hejuru zivuye mubisubizo byayo bikomeye bikomeza ibintu, molybdenum, cobalt na chromium, hamwe nibintu bikomera imyaka, aluminium na titanium.Imbaraga zayo hamwe no guhagarara neza birenze hejuru ya thosetypically iboneka kuri alloy 718.

Imyaka ikomantaza idasanzwe ya nikel, imbaraga zikomeye muri 1400-1600 ° F. Kurwanya okiside ikoreshwa muri moteri ya gaz turbine kuri 1400-1600 ° F.Muri 1150-1150 ° F, Waspaloy creep yaturika imbaraga zirenze iyo muri 718.
Ku gipimo cya 0-1350 ° F, imbaraga zishyushye mugihe gito ni mbi kurenza 718
Waspaloy ikoreshwa mubikoresho bya moteri ya gaz turbine isaba imbaraga nyinshi no kurwanya ruswa kubushyuhe bwo hejuru. Ubusanzwe nibishobora gukoreshwa harimo disiki ya compressor na rotor, shafts, icyogajuru, kashe, impeta na casings,kwizirika hamwe nibindi byuma bya moteri zitandukanye, guteranya ikirere hamwe na sisitemu ya misile.
