Ma aluminiyamu a mkuwa (Cu) ndi mkuwa-nickel (mkuwa-nickel (Cu-Ni) ndi zinthu zamtengo wapatali, koma kapangidwe kake ndi makhalidwe ake osiyanasiyana zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito mosiyanasiyana. Kumvetsetsa kusiyana kumeneku ndikofunikira kwambiri posankha zinthu zoyenera ntchito yanu—ndipo pankhani ya malo ovuta, zinthu zathu za Cu-Ni zimaonekera ngati chisankho chabwino kwambiri.
Pakati pake, mkuwa woyera ndi chitsulo chofewa, chofewa chomwe chimadziwika ndi mphamvu yabwino kwambiri yamagetsi komanso kutentha. Ndi chofewa kwambiri, zomwe zimapangitsa kuti chikhale chosavuta kupanga mawaya, mapaipi, ndi mapepala, zomwe zimapangitsa kuti chigwiritsidwe ntchito kwambiri mu mawaya amagetsi ndi zosinthira kutentha. Komabe, mkuwa woyera uli ndi zoletsa zazikulu: umakonda dzimbiri m'malo ovuta, makamaka ukakumana ndi madzi amchere, ma acid, kapena zoipitsa mafakitale. Pakapita nthawi, umapanga patina wobiriwira (oxidation layer), womwe ungafooketse zinthuzo ndikuwononga magwiridwe antchito monga kukonza zam'madzi kapena mankhwala.
Ma aloyi a Cu-NiMosiyana ndi zimenezi, sakanizani mkuwa ndi nickel (nthawi zambiri 10-30% nickel, kuphatikiza chitsulo ndi manganese pang'ono) kuti muthane ndi zofookazi. Kusakaniza kumeneku kumasintha mawonekedwe a chinthucho, kuyambira ndikukana dzimbiri kwapamwambaKuchuluka kwa nickel kumapanga gawo loteteza okosijeni lomwe limalimbana ndi dzenje, dzimbiri, ndi kukokoloka kwa nthaka—ngakhale m'madzi amchere, madzi amchere, kapena zinyalala zamafakitale. Izi zimapangitsa Cu-Ni kukhala yoyenera pazinthu zam'madzi monga zombo, njira zolowera madzi a m'nyanja, ndi mapaipi opangira mafuta a m'nyanja, komwe mkuwa weniweni ungawonongeke msanga.
Mphamvu ya makina ndi gawo lina lomwe Cu-Ni imagwira ntchito bwino kuposa mkuwa weniweni. Ngakhale mkuwa weniweni ndi wochepa, ulibe mphamvu yokoka yofunikira pakugwiritsa ntchito mphamvu zambiri. Ma alloy a Cu-Ni, chifukwa cha zinthu zomwe amapangira, amapereka mphamvu zambiri komanso kuuma, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pazinthu zolemera monga mapampu, ma valve, ndi machubu osinthira kutentha. Amasunganso kusinthasintha, zomwe zimapangitsa kuti zikhale zosavuta kupanga popanda kuwononga kulimba.
Ponena za kutentha ndi magetsi, mkuwa weniweni umatsogolerabe, koma Cu-Ni imasunga mphamvu zokwanira zogwirira ntchito m'mafakitale ambiri—komanso kuwonjezera phindu lofunika kwambiri la kukana dzimbiri. Kulinganiza kumeneku kumapangitsa Cu-Ni kukhala chinthu chosankhidwa m'malo omwe magwiridwe antchito ndi moyo wautali ndizofunikira.
Zogulitsa zathu za Cu-Ni zapangidwa kuti zigwiritse ntchito bwino maubwino awa. Zimapezeka m'njira zosiyanasiyana (mawaya, mapepala, machubu() ndi zinthu zopangidwa ndi nickel, zimapangidwa molondola kuti zikwaniritse miyezo yokhwima yamakampani. Kaya ndi za uinjiniya wa m'madzi, kukonza mankhwala, kapena makina amafakitale, zinthu zathu za Cu-Ni zimapereka kudalirika, moyo wautali, komanso kugwiritsa ntchito bwino ndalama zomwe mkuwa weniweni sungagwirizane nazo. Sankhani Cu-Ni ngati mukufuna kugwiritsa ntchito komwe magwiridwe antchito m'mikhalidwe yovuta sangakambiranedwe—ndipo khulupirirani kuti zinthu zathu zipitilira zomwe mukuyembekezera.
