Nimonic 80A yog superalloy nrog Ni Cr raws li cov matrix thiab txhuas thiab titanium li matrix los ua Y theem dispersion ntxiv dag zog.Tsuas yog cov ntsiab lus aluminium siab dua me ntsis, Nimonic 80A zoo ib yam li GH4033.Qhov kev pabcuam kub yog 700-800 ℃, thiab nws muaj kev nkag siab zoo thiab oxidation tsis kam ntawm 650-850 ℃.
Lub alloy muaj kev ua haujlwm txias thiab kub ua haujlwm zoo.Nws tsuas yog siv cov khoom kub dov, txias rub bar, cov ntawv kub dov, ntawv txias dov, strip thiab annular qhov chaw, thiab lwm yam, uas yog siv los tsim cav rotor hniav, qhia vane bearings, bolts, nplooj xauv daim hlau thiab lwm yam.
