Kuponyedwa kwa mkuwa kumagwiritsidwa ntchito kwambiri mu valve ndi pampu chifukwa cha ntchito yabwino ya zipangizo zamkuwa. Ku RMC Foundry, timapanga makamakazitsulo zamkuwandi kuponya mchenga wobiriwira, utomoni wokutira mchenga,kuponya ndalamandi zoponya zazikulu zamkuwa, timatengeranso njira yotayira thovu ndi vacuum. Nthawi zambiri, ma castings amkuwa opangidwa ndi kuponya mchenga ndiye gulu lalikulu muzoyambira zathu.
Aloyi yamkuwa yokhala ndi zinki monga chinthu chachikulu cholumikizira nthawi zambiri chimatchedwa mkuwa. Copper-zinki binary alloy amatchedwa wamba mkuwa, ndipo ternary, quaternary kapena multielement mkuwa wopangidwa ndi kuwonjezera pang'ono zinthu zina pamaziko a aloyi yamkuwa-zinki amatchedwa mkuwa wapadera. Cast brass amagwiritsidwa ntchito kupanga mkuwa popanga castings. Kuponyedwa kwa mkuwa kumagwiritsidwa ntchito kwambiri popanga makina, ma valve ndi mapampu, zombo, ndege, magalimoto, zomangamanga ndi mafakitale ena, okhala ndi zolemera zina zazitsulo zolemera zopanda chitsulo, kupanga mndandanda wazitsulo zamkuwa.
Poyerekeza ndi mkuwa ndi mkuwa, kusungunuka kolimba kwa zinki mumkuwa ndi kwakukulu kwambiri. Pansi pa kutentha kwanthawi zonse, pafupifupi 37% ya zinc imatha kusungunuka mkuwa, ndipo pafupifupi 30% ya zinc imatha kusungunuka m'malo otayira, pomwe malata amkuwa Mumkhalidwe wa as-cast, gawo lalikulu la kusungunuka kolimba kwa malata. mumkuwa ndi 5% mpaka 6%. Gawo lalikulu la kusungunuka kolimba kwa aluminiyumu mkuwa wamkuwa ndi 7% mpaka 8%. Chifukwa chake, zinc imakhala ndi njira yabwino yolimbikitsira mkuwa. Panthawi imodzimodziyo, zinthu zambiri zowonjezera zimatha kusungunuka mkuwa ku madigiri osiyanasiyana , Komanso kupititsa patsogolo makina ake, kotero kuti mkuwa, makamaka mkuwa wapadera uli ndi makhalidwe amphamvu kwambiri. Mtengo wa zinki ndi wotsika kuposa wa aluminiyamu, mkuwa, ndi malata, ndipo uli ndi zinthu zambiri. Kuchuluka kwa zinki komwe kumawonjezeredwa ku mkuwa ndikokulirapo, motero mtengo wamkuwa ndi wotsika kuposa mkuwa wa malata ndi mkuwa wa aluminiyamu. Brass ili ndi kutentha pang'ono kolimba, madzi abwino, komanso kusungunula kosavuta.
Chifukwa mkuwa uli ndi makhalidwe omwe tawatchulawa amphamvu kwambiri, mtengo wotsika komanso ntchito yabwino yoponyera, mkuwa uli ndi mitundu yambiri, zotulutsa zazikulu komanso ntchito zambiri kuposa mkuwa wa malata ndi mkuwa wa aluminiyamu muzitsulo zamkuwa. Komabe, kukana kuvala ndi kukana kwa mkuwa sikuli bwino ngati mkuwa, makamaka kukana kwa dzimbiri ndi kukana kwa mkuwa wamba ndizochepa. Pokhapokha pamene zinthu zina za alloy ziwonjezeredwa kuti zipange mkuwa wapadera wapadera, kukana kwake kuvala ndi kukana kwa dzimbiri kwasinthidwa ndikuwongolera.
Zopangira zamkuwa ndi zopangira zamkuwa zonse ndizopangidwa ndi aloyi zamkuwa zomwe zimatha kuponyedwa ndi mchenga komanso njira zopangira ndalama. Brass ndi aloyi wopangidwa ndi mkuwa ndi zinc. Mkuwa wopangidwa ndi mkuwa ndi nthaka umatchedwa mkuwa wamba. Ngati ndi mitundu yosiyanasiyana ya aloyi wopangidwa ndi zinthu zoposa ziwiri, amatchedwa mkuwa wapadera. Brass ndi aloyi yamkuwa yokhala ndi zinc monga chinthu chachikulu. Pamene nthaka zili kuwonjezeka, mphamvu ndi plasticity aloyi kuchuluka kwambiri, koma mawotchi katundu adzachepa kwambiri pambuyo kuposa 47%, kotero nthaka zili mkuwa ndi zosakwana 47%. Kuphatikiza pa nthaka, mkuwa wonyezimira nthawi zambiri umakhala ndi zinthu monga silicon, manganese, aluminium, ndi lead.
