Copper (Cu) ndi copper-nickel (copper-nickel (Cu-Ni) alloys onse ndi zinthu zamtengo wapatali, koma zolemba zawo zosiyana ndi katundu zimawapangitsa kukhala oyenerera ntchito zosiyanasiyana.
Pakatikati pake, mkuwa wangwiro ndi chitsulo chofewa, chosasunthika chomwe chimadziwika ndi mphamvu yabwino kwambiri yamagetsi ndi matenthedwe. Ndi ductile kwambiri, zomwe zimapangitsa kuti zikhale zosavuta kuzipanga kukhala mawaya, mapaipi, ndi mapepala, zomwe zimafotokoza momwe zimagwiritsidwira ntchito ponseponse pa mawaya amagetsi ndi zotenthetsera. Komabe, mkuwa wangwiro uli ndi malire ovuta: umakonda dzimbiri m'malo ovuta, makamaka ukakumana ndi madzi amchere, ma acid, kapena zowononga mafakitale. M'kupita kwa nthawi, amapanga patina wobiriwira (oxidation wosanjikiza), yomwe imatha kufooketsa zinthuzo ndikusokoneza magwiridwe antchito ngati m'madzi kapena kukonza mankhwala.
Cu-Ni aloyi, mosiyana, phatikizani mkuwa ndi nickel (kawirikawiri 10-30% nickel, kuphatikizapo chitsulo chochepa ndi manganese) kuti athetse zofookazi. Kuphatikiza uku kumasintha zinthu zakuthupi, kuyambirakukana dzimbiri kwapamwamba. Nickel yomwe ili nayo imapangitsa kuti oxide itetezeke yomwe imalimbana ndi pitting, corrosion, ndi kukokoloka - ngakhale m'madzi amchere, madzi amchere, kapena utsi wa m'mafakitale. Izi zimapangitsa Cu-Ni kukhala yabwino pazinthu zam'madzi monga zombo zapamadzi, makina otengera madzi a m'nyanja, ndi mapaipi amafuta akunyanja, komwe mkuwa woyengeka ungawonongeke msanga.
Mphamvu zamakina ndi malo ena omwe Cu-Ni amaposa mkuwa wangwiro. Ngakhale mkuwa weniweni ndi ductile, ulibe mphamvu zolimba zomwe zimafunikira pakupanikizika kwambiri. Ma aloyi a Cu-Ni, chifukwa cha ma aloyi awo, amapereka mphamvu komanso kuuma kwakukulu, zomwe zimawapangitsa kukhala oyenera pazigawo zolemetsa monga mapampu, ma valve, ndi machubu osinthanitsa kutentha. Amakhalanso ndi kusinthasintha, kulola kuti apange mosavuta popanda kusiya kupirira.
Pankhani ya matenthedwe amafuta ndi magetsi, mkuwa wangwiro umatsogolerabe, koma Cu-Ni imasunga ma conductivity okwanira pazosowa zambiri zamafakitale-pamene akuwonjezera phindu lalikulu la kukana dzimbiri. Kulinganiza kumeneku kumapangitsa Cu-Ni kukhala chinthu chosankha m'malo omwe magwiridwe antchito komanso moyo wautali zimafunikira.
Zogulitsa zathu za Cu-Ni zidapangidwa kuti zithandizire izi. Amapezeka m'njira zosiyanasiyana (mawaya, mapepala, machubu) ndi nyimbo za nickel, zimapangidwa molondola kuti zikwaniritse miyezo yolimba yamakampani. Kaya ndi mainjiniya apanyanja, kukonza mankhwala, kapena makina am'mafakitale, zinthu zathu za Cu-Ni zimapereka kudalirika, moyo wautali, komanso zotsika mtengo zomwe mkuwa weniweni sungafanane. Sankhani Cu-Ni pazogwiritsa ntchito zomwe sizingakanjanitsidwe m'mikhalidwe yovuta - ndipo khulupirirani kuti malonda athu apitilira zomwe mukuyembekezera.
