Aluminium iri ahantu hose hakenewe imiterere yoroheje cyangwa ubushyuhe bwinshi n'amashanyarazi. Igare risanzwe rya siporo rifite silinda ya aluminiyumu, umutwe, na crankcases, hamwe na chassis ya aluminiyumu na swingarm. Muri moteri, ikoreshwa ry'ingenzi rya aluminiyumu ni pistons zayo, zishobora kwihanganira ubushyuhe bukabije hejuru cyane y'aho zishongeshereza. Amapine, radiator zikonjesha n'amavuta, levers z'intoki n'udukingirizo twazo, amakamba yo hejuru n'ayo hasi, imiyoboro yo hejuru (muri fork za USD), calipers za feri, na silinda nini na byo ni aluminiyumu.

Twese twarebye dutangarira icyuma cya aluminiyumu gifite imitako isa n'urukuta rw'udupira twa poker twaguye. Zimwe muri izi mashini n'ingufu, nk'iz'abakinnyi ba Aprilia ba 250, ni ibihangano byiza by'ubuhanzi.

Aluminiyumu ishobora guhindurwamo imvange no gushyushya kugeza ku mbaraga zirenze iz'icyuma cyoroshye (60.000 psi tensile), nyamara inyinshi muri zo zikora vuba kandi byoroshye. Aluminiyumu ishobora kandi gucurwa, gucurwa, cyangwa gukurwamo (ni ko imirasire imwe n'imwe yo ku ruhande ikorwa). Uburyo aluminiyumu ikoresha ubushyuhe bwinshi butuma isudira yayo ikenera amperage nyinshi, kandi icyuma gishyushye kigomba kurindwa ogisijeni yo mu kirere hakoreshejwe uburyo bwo kurinda imyuka idafite umwuka (TIG cyangwa heli-arc).

Nubwo aluminiyumu ikenera amashanyarazi menshi kugira ngo ikure mu mabuye yayo ya bauxite, iyo ibayeho mu buryo bw'icyuma, igura make kuyikoresha kandi ntizibura ingese, nk'uko icyuma gishobora kumera.

Abakora moteri za moto ba mbere bahise bakoresha icyuma gishya icyo gihe cyo gukoresha mu byuma binini, ibyo bitabaye ibyo byari kuba icyuma gikozwe mu cyuma gipima hafi inshuro eshatu. Aluminiyumu yoroheje ni yoroshye cyane—Ndibuka uburakari mama yagize ku kuba papa yarakoresheje icyuma cye cya 1.100-alloy double-boiler nk'umutego wa BB wakozwe mu buryo butunguranye: Hasi hacyo hahindutse uduce duto.

Ingufu ziyongereye z’icyuma gikozwe mu muringa cyavumbuwe vuba, kandi ni cyo kintu cyakoreshejwe n’umucuranzi WO Bentley mu gukora igerageza rya piston za aluminiyumu mbere y’Intambara ya Mbere y’Isi Yose. Mu igerageza ryikurikiranya ku mapiston y’icyuma yari akomeye icyo gihe, piston za aluminiyumu za Bentley zagerageje bwa mbere zahise zongera imbaraga. Zakonjeshaga, zishyushya uruvange rw’amavuta n’umwuka byinjiraga gake, kandi zigumana ubucucike bwinshi. Muri iki gihe, piston za aluminiyumu zikoreshwa cyane muri moteri z’imodoka na moto.

Kugeza igihe indege ya Boeing yo mu bwoko bwa 787 ifite icyuma gikonjesha cya karubone, byari ibintu by'ingenzi mu by'indege ko hafi ya buri ndege ifite uburemere butari buhagije bwari aluminiyumu 60 ku ijana. Urebye uburemere n'imbaraga bya aluminiyumu n'icyuma, ibi bisa nkaho bitangaje. Yego, aluminiyumu ipima 35 ku ijana gusa ugereranyije n'icyuma, ingano ugereranyije n'ingano, ariko ibyuma bikomeye bifite imbaraga zikubye nibura gatatu ugereranyije na aluminiyumu ikomeye. Kuki tutakora indege mu cyuma gito?

Byatewe no kudakomera kw'inyubako zingana za aluminiyumu n'icyuma. Iyo dutangiye n'imiyoboro ya aluminiyumu n'icyuma ifite uburemere bumwe kuri buri kirenge, maze tukagabanya ubugari bw'urukuta, umuyoboro w'icyuma ubanza gufunga kuko ibikoresho byawo, kuko ari kimwe cya gatatu cy'ubunini bwa aluminiyumu, nta bushobozi bwo kwirwanaho buhagije.

Mu myaka ya za 1970, nakoranye n'umwubatsi w'amasafuriya Frank Camillieri. Ubwo namubazaga impamvu tutakoresheje imiyoboro minini y'icyuma yo ku rukuta rworoshye kugira ngo dukore amasafuriya yoroshye kandi akomeye, yaravuze ati: “Iyo ubikoze, usanga ugomba kongeramo ibikoresho byinshi ku bintu nk'ibikoresho byo gushyiramo moteri kugira ngo bitazacika, bityo kugabanya ibiro bishire.”

Kawasaki yatangiye gukoresha imbunda za aluminiyumu ku magare yayo yo mu ruganda rwa MX mu ntangiriro ya za 1970; izindi nazo zarabikoze. Hanyuma mu 1980, Yamaha yashyize Kenny Roberts ku igare rya GP rifite imiterere 500 ifite imiterere ibiri, imiterere yaryo yari yakozwe mu muyoboro wa aluminiyumu ukozwe mu gice cya kare. Byari ngombwa gukora igerageza ryinshi mu gushushanya, ariko amaherezo, hakoreshejwe ibitekerezo by'umuhanga w'Umwesipanyoli Antonio Cobas, imiterere y'umuhanda wa GP ya Yamaha yahindutse imirasire minini ya aluminiyumu isanzwe imenyerewe muri iki gihe.

Nta gushidikanya ko hari ubwoko bw'urusobe rw ...

Irindi tandukaniro rikomeye hagati y'icyuma na aluminiyumu ni uko icyuma gifite icyo bita umupaka w'umunaniro: urwego rw'umuvuduko wo gukora ruri munsi yarwo aho igihe cy'ubuzima bw'igice kiba kitagira umupaka. Ibyuma byinshi bya aluminiyumu bitagira umupaka w'umunaniro, niyo mpamvu ibyuma bya aluminiyumu "bimara" amasaha yagenwe yo gukoreshwa. Munsi y'uyu mupaka, icyuma kiduharira amakosa yacu, ariko aluminiyumu yibuka ibitutsi byose mu buryo bw'ibyangiritse imbere mu munaniro bitagaragara.

Chassis nziza ya GP yo mu myaka ya 1990 ntiyashoboraga kuba ishingiro ry’umusaruro mwinshi. Iyo chassis yari igizwe n’ibice byahujwe hamwe bivuye mu bikoresho bya mashini, byasutswe, n’ibyakozwe muri aluminiyumu. Ntabwo ari ibintu bigoye gusa, ahubwo bisaba ko alloys zose uko ari eshatu zishobora gusukirwa. Gusudira bisaba amafaranga n’igihe, kabone n’iyo byaba bikorwa n’amarobo akora.

Ikoranabuhanga ryatumye moteri zoroshye zo muri iki gihe zikoresha ibyuma bine na chassis yo mu bwoko bwa cast zishoboka ni uburyo bwo kuzuza ibumba ridakoresha turbulence nyinshi, ridashyiramo filime za aluminium oxide zihita zikora kuri aluminium ishongeshejwe. Filime nk'izo zikora ahantu hafite intege nke mu byuma, mu gihe cyashize, byasabaga ko castings ziba nini cyane kugira ngo zigere ku mbaraga zihagije. Ibice by'icyuma biva muri izi nzira nshya bishobora kuba bigoye cyane, nyamara chassis ya aluminium yo muri iki gihe ishobora guteranywa hakoreshejwe ibyuma bisudira bibarwa ku ruhande rumwe. Bivugwa ko uburyo bushya bwo gushushanya buzigama ibiro 30 cyangwa birenga by'uburemere muri moto zikora.

Hamwe n'ubwoko bwinshi bw'ibyuma, aluminiyumu ni ikintu cy'ibanze mu mibereho y'abantu, ariko ni byinshi kurusha ibyo kuri moto zigezweho. Ni ikintu cy'ingenzi mu igare, gikunze kugaragara hose ku buryo tutakibona cyangwa ngo twemere imikorere y'imashini tubikesha.
