Nimonic 80A is a superalloy ine Ni Cr sematrix uye aruminiyamu uye titanium sematrix yekugadzira Y phase dispersion kusimbisa.Kunze kweiyo yakakwira zvishoma aluminium yemukati, Nimonic 80A yakafanana neGH4033.Tembiricha yebasa ndeye 700-800 ℃, uye ine yakanaka inokambaira kuramba uye oxidation kuramba pa650-850 ℃.
Iyo alloy ine yakanaka kutonhora uye inopisa kushanda kushanda.Iyo inonyanya kupa inopisa yakatenderedzwa bar, inotonhora inodhonzwa bhawa, inopisa yakatenderedzwa shiti, inotonhora yakatenderedzwa pepa, mitsetse uye annular zvikamu, nezvimwe, izvo zvinoshandiswa kugadzira injini rotor blades, kutungamira vane mabheji, mabhaudhi, mashizha ekuvhara mahwendefa uye zvimwe zvikamu.
