ʻO Nimonic 80A kahi superalloy me Ni Cr e like me ka matrix a me ka aluminika a me ka titanium e like me ka matrix e hoʻoikaika i ka hoʻopuehu Y.Ma waho aʻe o ka waihona alumini kiʻekiʻe, ua like ʻo Nimonic 80A me GH4033.ʻO ka mahana o ka lawelawe he 700-800 ℃, a he maikaʻi kona kūpaʻa ʻana a me ke kūpaʻa oxidation ma 650-850 ℃.
He maikaʻi ke anuanu a me ka hana wela o ka alloy.Hāʻawi nui ia i ka pā ʻōwili wela, ka pahu huki anu, ka pepa i ʻōwili ʻia, ka pepa i ʻōwili ʻia, ka ʻāpana a me nā ʻāpana annular, a me nā mea ʻē aʻe, i hoʻohana ʻia no ka hana ʻana i nā ʻāpana rotor engine, alakaʻi i nā bearings, bolts, nā papa laka lau a me nā ʻāpana ʻē aʻe.
