Refractaloy 26 waa Fe - NI - Co - Cr da'da adkeysiga nooca qallafsanaanta daawaynta heerkulka sare, isticmaalka muddada-dheer ee C - 570 ℃ heerkulka kala duwan ee 540 ℃, heerkulka ugu sarreeya wuxuu gaari karaa 677 C, ku dar element ah Cr, mo alloy Xalka adag ee xoojinta, titanium sare ilaa hooseeya, qaabka aluminium y wejiga xoojinta gabowga, halka walxaha qodista laga sameeyay titanium, aluminium aluminium ee xalka adag waa la dhimay, waxay keentay y heerka roobabka wejiga korodhka, si loo hagaajiyo xasilloonida kuleylka y, la yareeyo y'wajiga tamarta qaladka ee is dulsaarka.
Qalabka isku dhafan ee daawaha ayaa ka sarreeya, oo leh iska caabin aad u fiican, nasashada xoogga iyo iska caabinta gurguurta, ma laha dareen dareen ah.

Daawaha ayaa loo isticmaalay in wax soo saarka ee marawaxadaha uumiga dhulka, hoos xaaladaha uumiga 540 ℃ ~ 570 ℃ shaqayn kara in ka badan 100,000 saacadood, xaalad isticmaalka waa good. Alloys la mid ah ayaa loo isticmaalaa dibadda si ay u sameeyaan aero turbine engine qaybo kakan. iyo garbahaThe alloy waxay leedahay caag wanaagsan heerkulka dhexdhexaadka ah, taas oo yareyn karta jabka qaybaha sababtoo ah adkeysiga iyo gurguurta isticmaalka muddada dheer. kala duwanaanta heerkulka
