Mawu Oyamba
Super alloys amatha kugwira ntchito pa kutentha kwambiri komanso kupsinjika kwamakina, komanso komwe kukhazikika kwapamwamba kumafunika.Amakhala ndi kukwapula bwino komanso kukana kwa okosijeni, ndipo amatha kupangidwa mosiyanasiyana.Amatha kulimbikitsidwa ndi kuuma kwazitsulo zolimba, kuuma kwa ntchito, ndi kuuma kwa mvula.
Super alloys imakhala ndi zinthu zingapo zophatikizika zosiyanasiyana kuti mukwaniritse zomwe mukufuna.Amagawidwanso m'magulu atatu monga cobalt-based, nickel-based, ndi iron-based alloys.
Inkoloy(r) alloy 825 ndi aloyi ya nickel-iron-chromium ya austenitic yomwe imawonjezeredwa ndi zinthu zina zopangira kuti ipititse patsogolo katundu wake wosagwirizana ndi dzimbiri.Tsamba lotsatirali lipereka zambiri za Inkoloy(r) alloy 825.
