Borokho ke boqapi ba bohlokoa historing ea batho. Ho tloha mehleng ea boholo-holo ha batho ba ne ba sebelisa lifate tse remiloeng le majoe a phuthetsoeng ho tšela litselana tsa metsi le likhohlo, ho ea ho tšebeliso ea marokho a arch esita le marokho a kentsoeng ka likhoele, khopolo ea ho iphetola ha lintho e bile e tsotehang. Ho buloa haufinyane ha Borokho ba Hong Kong-Zhuhai-Macao ho tšoaea ketsahalo ea bohlokoa nalaneng ea marokho. Kaho ea borokho ea morao-rao, ntle le ho sebelisa mehaho ea konkreite e matlafalitsoeng, lisebelisoa tsa tšepe, haholo-holo li-alloys tsa aluminium, li fetohile khetho e tloaelehileng ka lebaka la melemo ea bona e sa tšoaneng.
Ka 1933, ho ile ha sebelisoa borokho ba pele ba lefatše ba aluminium borokho bo pota-potileng nōka ea Pittsburgh, United States. Lilemo tse fetang leshome hamorao, ka 1949, Canada e ile ea qeta borokho ba aluminium kaofela bo haola le Noka ea Saguenay e Quebec, bo bolelele ba limithara tse 88,4. Borokho bona e ne e le mohaho oa pele oa lefats'e oa all-aluminium alloy. Borokho bo ne bo e-na le likotopo tse bolelele ba limithara tse 15 le litselana tse peli tsa sephethephethe sa likoloi. E ne e sebelisa motsoako oa aluminium oa 2014-T6 mme e ne e e-na le boima ba lithane tse 163. Ha ho bapisoa le borokho ba tšepe bo neng bo reriloe qalong, bo fokolitse boima ba 'mele ka hoo e ka bang 56%.
Ho tloha ka nako eo, mokhoa oa marokho a aluminium alloy structural ha o e-s'o thijoe. Pakeng tsa 1949 le 1985, United Kingdom e ile ea haha marokho a ka bang 35 a aluminium alloy structural, ha Jeremane e haha marokho a joalo a ka bang 20 pakeng tsa 1950 le 1970. Ho hahoa ha marokho a mangata ho fane ka phihlelo ea bohlokoa bakeng sa lihahi tsa borokho tsa aluminium tsa nakong e tlang.
Ha li bapisoa le tšepe, lisebelisoa tsa alloy aluminium li na le boima bo tlaase, bo etsang hore li be bobebe haholo, li na le 34% feela ea boima ba tšepe bakeng sa molumo o tšoanang. Leha ho le joalo, li na le matla a tšoanang le a tšepe. Ho feta moo, li-alloys tsa aluminium li bonts'a elasticity e ntle haholo le ho hanyetsa kutu ha li ntse li na le litšenyehelo tse tlase tsa tlhokomelo ea meralo. Ka lebaka leo, ba fumane ts'ebeliso e kholo kahong ea borokho ea sejoale-joale.
China e hatetse pele haholo kahong ea borokho. Borokho ba Zhaozhou, bo emeng lilemo tse fetang 1500, ke e 'ngoe ea likatleho tsa mantlha tsa boenjineri ba borokho ba khale ba Machaena. Mehleng ea kajeno, ka thuso ea Soviet Union ea mehleng, Chaena e ile ea boela ea haha marokho a ’maloa a tšepe, ho akarelletsa le marokho a Nōka ea Yangtze e Nanjing le Wuhan, hammoho le Pearl River Bridge e Guangzhou. Leha ho le joalo, ts'ebeliso ea marokho a aluminium alloy naheng ea China e bonahala e lekanyelitsoe. Borokho ba pele ba aluminium alloy structural borokho ba Chaena e ne e le borokho ba ba tsamaeang ka maoto Qingchun Road Hangzhou, bo hahiloeng ka 2007. Borokho bona bo entsoe le ho kenngoa ke baenjiniere ba borokho ba Jeremane, 'me lisebelisoa tsohle li ne li romelloa ho tsoa Jeremane. Selemong sona seo, borokho ba ba tsamaeang ka maoto bo Xujiahui, Shanghai, bo ile ba ntlafatsoa ka botlalo 'me ba etsoa ka har'a naha ho sebelisoa meaho ea aluminium alloy. Haholo-holo e ne e sebelisa 6061-T6 aluminium alloy mme, leha e le boima ba lithane tse 15, e ne e ka ts'ehetsa boima ba lithane tse 50.
Nakong e tlang, marokho a aluminium alloy a na le tebello e kholo ea nts'etsopele Chaena ka mabaka a 'maloa:
1 Kaho ea seporo sa lebelo le holimo ea China e ntse e ata, haholo-holo libakeng tse rarahaneng tsa libaka tse ka bophirima tse nang le liphula le linōka tse ngata. Marokho a Aluminium alloy, ka lebaka la boiketlo ba bona ba lipalangoang le thepa e bobebe, e lebelletsoe ho ba le 'maraka o moholo o ka bang teng.
2 Lisebelisoa tsa tšepe li na le mafome 'me li na le ts'ebetso e fokolang mochesong o tlase. Ho bola ha tšepe ho ama haholo botsitso ba borokho, ho fella ka litšenyehelo tse phahameng tsa tlhokomelo le likotsi tsa polokeho. Ka lehlakoreng le leng, lisebelisoa tsa aluminium alloy li na le matla a ho thibela kutu 'me li sebetsa hantle ka mocheso o tlase, li etsa hore li tšoanele maemo a fapaneng a leholimo le ho netefatsa hore li tšoarella nako e telele. Le hoja marokho a aluminium alloy a ka ba le litšenyehelo tse phahameng tsa kaho ea pele, litšenyehelo tsa bona tse tlaase tsa tlhokomelo li ka thusa ho fokotsa lekhalo la litšenyehelo ka nako.
3 Lipatlisiso mabapi le liphanele tsa borokho tsa aluminium, ka hare ho naha le kantle ho naha, li ntlafalitsoe hantle, 'me lisebelisoa tsena li sebelisoa haholo. Tsoelo-pele ea lipatlisiso tsa thepa e fana ka tiisetso ea tekheniki bakeng sa ho hlahisa li-alloys tse ncha tse finyellang litlhoko tse fapaneng tsa tshebetso. Baetsi ba aluminium ba Machaena, ho kenyeletsoa linatla tsa indasteri tse kang Liaoning Zhongwang, butle-butle ba fetisitse maikutlo a bona ho profiles ea aluminium ea indasteri, ba rala motheo oa kaho ea borokho ba aluminium alloy.
4 Kaho e potlakileng ea literene tse tsamaeang ka tlas'a lefatše metseng e meholo ea Chaena e beha litlhokahalo tse thata bakeng sa meaho e tsoang holimo. Ka lebaka la melemo ea tsona e kholo ea boima ba 'mele, hoa hlokomeleha esale pele hore marokho a mangata a aluminium alloy a tla raloa le ho sebelisoa nakong e tlang.
