Aluminiyamu inayamba kudziwika ngati chinthu mu 1782, ndipo chitsulocho chinali ndi kutchuka kwakukulu ku France, komwe m'ma 1850 chinali chapamwamba kuposa golide ndi siliva zodzikongoletsera ndi ziwiya zodyera. Napoleon III anachita chidwi ndi mmene chitsulo chopepuka chimagwiritsidwira ntchito pankhondo, ndipo anapereka ndalama zoyeserera koyambirira pochotsa aluminiyamu. Ngakhale kuti chitsulocho chimapezeka mochuluka m'chilengedwe, ntchito yochotsa bwino imakhalabe yovuta kwa zaka zambiri. Aluminiyamu idakhalabe yokwera mtengo kwambiri motero idagwiritsidwa ntchito pang'ono pazamalonda m'zaka zonse za 19th. Kupita patsogolo kwaumisiri kumapeto kwa zaka za zana la 19 potsiriza kunalola kuti aluminiyamu asungunuke motsika mtengo, ndipo mtengo wazitsulo unagwa kwambiri. Izi zinatsegula njira yopititsira patsogolo ntchito zamafakitale zachitsulo.
Aluminiyamu sankagwiritsidwa ntchito m'zitini zakumwa mpaka nkhondo yachiwiri ya padziko lonse itatha. Panthawi yankhondo, boma la United States linatumiza mowa wochuluka m’zitini zachitsulo kwa ogwira ntchito ake kunja kwa nyanja. Nkhondo itatha moŵa wambiri unagulitsidwanso m’mabotolo, koma asilikali obwererawo anapitirizabe kukonda zitini. Opanga anapitiriza kugulitsa mowa wina m’zitini zachitsulo, ngakhale kuti mabotolo anali otsika mtengo kupanga. Kampani ya Adolph Coors inapanga mowa woyamba wa aluminiyamu mu 1958. Zigawo zake ziwiri zimatha kukhala ndi ma ounces 7 (198 g), m'malo mwa 12 g (340 g), ndipo panali mavuto ndi kupanga. Komabe, aluminiyumuyo imatha kukhala yotchuka mokwanira kuti ilimbikitse Coors, pamodzi ndi makampani ena azitsulo ndi aluminiyamu, kupanga zitini zabwinoko.
Chitsanzo chotsatira chinali chidebe chachitsulo chokhala ndi aluminiyamu pamwamba. Chosakanizidwa ichi chikhoza kukhala ndi ubwino wambiri. Mapeto a aluminiyumu adasintha momwe mowawo umakhalira pakati pa mowa ndi chitsulo, zomwe zidapangitsa kuti moŵa ukhale ndi nthawi ya aluminiyamu yomwe imasungidwa m'zitini zazitsulo zonse. Mwinamwake phindu lalikulu la pamwamba pa aluminiyumu linali lakuti chitsulo chofewa chikhoza kutsegulidwa ndi tabu yosavuta yokoka. Zitini za sitayelo zakale zinkafuna kugwiritsa ntchito chotsegulira chapadera chomwe chimatchedwa "kiyi ya tchalitchi," ndipo pamene Schlitz Brewing Company inayambitsa mowa wake mu aluminiyamu "pop top" mu 1963, opanga moŵa ena akuluakulu mwamsanga analumphira pa ngolo yovina. Pofika kumapeto kwa chaka chimenecho, 40% ya zitini zonse za mowa ku US zinali ndi nsonga za aluminiyamu, ndipo pofika 1968, chiwerengerochi chinali chitawirikiza kawiri mpaka 80%.
Ngakhale zitini zapamwamba za aluminiyamu zinali kusesa msika, opanga angapo anali ndi cholinga chofuna chakumwa chonse cha aluminiyamu. Ukadaulo wa Coors adagwiritsa ntchito kupanga aluminiyamu yake 7-ounce amatha kudalira njira ya "impact-extrusion",
Njira yamakono yopangira zitini zakumwa za aluminiyamu imatchedwa zojambula ziwiri ndi kusita pakhoma, zomwe zinayambitsidwa ndi kampani ya Reynolds Metals mu 1963.
kumene nkhonya yothamangitsidwa mu slug yozungulira inapanga pansi ndi mbali za chitini mu chidutswa chimodzi. Kampani ya Reynolds Metals inayambitsa aluminiyamu yonse yopangidwa ndi njira ina yotchedwa "kujambula ndi kusita" mu 1963, ndipo lusoli linakhala muyeso wa makampani. Coors ndi Hamms Brewery anali m'gulu la makampani oyambirira kuti atenge chitoliro chatsopanochi, ndipo PepsiCo ndi Coca-Cola anayamba kugwiritsa ntchito zitini zonse za aluminiyamu mu 1967. Chiwerengero cha zitini za aluminiyamu zomwe zinatumizidwa ku US zinakwera kuchokera ku theka la biliyoni mu 1965 kufika ku 8.5 biliyoni. 1972, ndipo chiwerengerocho chinapitirira kuwonjezeka pamene aluminiyamu inakhala chisankho chapadziko lonse cha zakumwa za carbonated. Chakumwa chamakono cha aluminiyamu sichimangokhala chopepuka kuposa chitsulo chakale kapena chitsulo ndi aluminiyamu, sichichita dzimbiri, chimazizira msanga, malo ake onyezimira ndi osavuta kusindikiza komanso owoneka bwino, amatalikitsa moyo wa alumali, ndipo ndi zosavuta kuzibwezeretsanso.
Aluminiyamu yomwe imagwiritsidwa ntchito muzakumwa zopangira chakumwa imachokera ku zinthu zobwezerezedwanso. Makumi makumi awiri ndi asanu peresenti ya aluminiyamu yonse ya ku America imachokera ku zinyalala zobwezerezedwanso, ndipo makampani opanga chakumwa ndi omwe amagwiritsa ntchito kwambiri zinthu zobwezerezedwanso. Kusungirako mphamvu kumakhala kofunikira pamene zitini zomwe zimagwiritsidwa ntchito zimatsitsimutsidwa, ndipo ma aluminiyamu amatha kubweza zitini zopitirira 63%.
Padziko lonse lapansi kupanga zitini zakumwa za aluminiyamu kukuchulukirachulukira, kukukulirakulira ndi zitini mabiliyoni angapo pachaka. Poyang'anizana ndi kufunikira kowonjezereka kumeneku, tsogolo la chakumwa likhoza kuwoneka ngati likugona mu mapangidwe omwe amasunga ndalama ndi zipangizo. Zomwe zimapangidwira zophimba zing'onozing'ono zikuwonekera kale, komanso ma diameter ang'onoang'ono a khosi, koma kusintha kwina sikungakhale koonekeratu kwa ogula. Opanga amagwiritsa ntchito njira zowunikira zowunikira kuti aphunzire zolemba, mwachitsanzo, kuyang'ana mawonekedwe achitsulo achitsulo ndi X-ray diffraction, ndikuyembekeza kupeza njira zabwinoko zoponyera ma ingots kapena kugudubuza mapepala. Kusintha kwa kaphatikizidwe ka aloyi wa aluminiyamu, kapena momwe aloyi amazilira pambuyo poponyedwa, kapena makulidwe omwe pepala lachitsulo limakulungidwa silingabweretse zitini zomwe zimakopa wogula ngati zatsopano. Komabe, mwina ndi kupita patsogolo m'magawo awa komwe kungapangitse kuti pakhale ndalama zambiri zopanga mtsogolo.
