Mkuwa ndi nthaka chifukwa chinthu chachikulu chaaloyi yamkuwa, ndi wokongola wachikasu, pamodzi anati ngati mkuwa. Copper zinc binary alloy amatchedwa mkuwa wamba kapena mkuwa wosavuta. Brass yokhala ndi ma yuan atatu imatchedwa mkuwa wapadera kapena mkuwa wovuta. Ma aloyi amkuwa okhala ndi zinc 36% koma amakhala ndi mayankho olimba ndipo amakhala ndi ntchito yabwino yozizira. Mwachitsanzo, mkuwa wokhala ndi 30% zinki nthawi zambiri umapanga zipolopolo za zipolopolo, zomwe zimatchedwa chipolopolo chamkuwa kapena makumi asanu ndi awiri mphambu atatu. Ma aloyi amkuwa okhala ndi zinki pakati pa 36 ndi 42% amapangidwa ndi njira zolimba, zomwe zimagwiritsidwa ntchito kwambiri ndi mkuwa wa hexagonal wokhala ndi zinc 40%. kuti apititse patsogolo kugwira ntchito kwa mkuwa wamba, zinthu zina nthawi zambiri zimawonjezeredwa, monga aluminiyamu, faifi tambala, manganese, malata, silicon, lead ndi zina. Aluminiyamu imatha kulimbitsa mphamvu, kuuma komanso kukana dzimbiri kwa mkuwa, koma kumachepetsa pulasitiki, kotero ndiyoyenera machubu a Marine condensing ndi mbali zina zolimbana ndi dzimbiri. Malata amatha kulimbitsa mphamvu ya mkuwa ndi dzimbiri kukana madzi a m'nyanja, motero amatchedwa Tobin bronze, yomwe imagwiritsidwa ntchito popanga zida zotenthetsera ndi zomangira. Kutsogolera kumatha kupititsa patsogolo ntchito yodula ya mkuwa. Mkuwa wodula uwu waulere umagwiritsidwa ntchito ngati gawo la wotchi. Zopangira zamkuwa nthawi zambiri zimakonda kupanga ma valve ndi zopangira mapaipi.
Bronze poyambilira amatanthauza aloyi yamkuwa, pambuyo pake ma aloyi amkuwa kupatula mkuwa ndi mkuwa woyera onse amatchedwa bronze, ndipo mkuwa nthawi zambiri umatsogozedwa ndi dzina la chinthu chachikulu chowonjezera. Mkuwa wa malata umakhala ndi ntchito yabwino yoponyera, kuchepetsa mikangano komanso makina amakina, oyenera kupanga mayendedwe, magudumu amagetsi kenako. Mkuwa wotsogolera ukhoza kukhala chinthu chomwe chimagwiritsidwa ntchito kwambiri pamainjini amakono ndi makina opera. Copper-base alloy ali ndi mphamvu zambiri, kukana bwino kuvala komanso kukana dzimbiri. amagwiritsidwa ntchito poponya magiya, ma bushings ndi ma propeller a Marine okhala ndi katundu wambiri. mkuwa ndi phosphatic mkuwa ndi mkulu zotanuka malire ndi madutsidwe wabwino magetsi, kuwapanga kukhala oyenera kupanga mwatsatanetsatane akasupe ndi zinthu tangency. bronze imagwiritsidwanso ntchito popanga zida zopanda utoto zomwe zimagwiritsidwa ntchito m'migodi ya malasha ndi zosungira mafuta.
Aloyi yamkuwa yokhala ndi faifi tambala chifukwa chachikulu chowonjezera. Cu-ni binary alloy amatchedwa mkuwa wamba woyera; Onjezani manganese, chitsulo, zinki, aluminium ndi zinthu zina za aloyi yamkuwa yoyera yotchedwa mkuwa wovuta. Mkuwa woyera wa mafakitale ugawika m'magulu awiri a mkuwa woyera ndi mkuwa woyera wamagetsi. Mapangidwe a mkuwa woyera amadziwika ndi zinthu zabwino zamakina ndi kukana kwa dzimbiri, mtundu wokongola. Mkuwa woyera umagwiritsidwa ntchito kwambiri m'makina olondola, makina opangira mankhwala ndi zigawo za Marine.
Dzina la Copper limachokera ku mtundu wake wofiira. sikuti ndi mkuwa wangwiro, ndipo nthawi zina pang'ono pang'ono za deoxidation zinthu kapena zinthu zina zimawonjezedwa kuti ziwonjezeke nsalu ndi magwiridwe antchito, motero zimatchulidwanso ngati aloyi yamkuwa. mogwirizana ndi zikuchokera Chinese mkuwa processing zipangizo zambiri amagawidwa m'magulu anayi: mkuwa wamba, mpweya wopanda mkuwa, deoxidized mkuwa, mkuwa wapadera ndi pang'ono kuchuluka kwa zinthu alloying. Mkuwa ndi wachiwiri kwa siliva mu conductivity ndi matenthedwe matenthedwe, ndipo chimagwiritsidwa ntchito popanga zida zamagetsi ndi matenthedwe conductive. Mkuwa mkati mwa mlengalenga, madzi a m'nyanja ndi zochepa zopanda oxidizing zidulo, alkali, mchere wa mchere ndi kufalikira kwa organic acid (acetic acid, citric acid), ali ndi kukana kwa dzimbiri, omwe amagwiritsidwa ntchito m'makampani. Kuphatikiza apo, mkuwa wofiyira umakhala ndi weldability wabwino, umapangidwa kukhala zinthu zingapo zomalizidwa pang'ono ndi zinthu zomalizidwa ndi kuzizira komanso kutentha kwa thermoplastic.
