Aluminiyamu (Al) ndi chitsulo chopepuka chodabwitsa chomwe chimagawidwa kwambiri m'chilengedwe. Lili ndi zinthu zambiri zosakaniza, ndipo pafupifupi matani 40 mpaka 50 biliyoni a aluminiyamu m’nthaka ya dziko lapansi, zomwe zimapangitsa kuti likhale chinthu chachitatu chochuluka kwambiri pambuyo pa okosijeni ndi silicon.
Aluminiyumu amadziwika chifukwa cha zinthu zake zabwino kwambiri, amakhala ndi malo ofunikira pakati pamitundu yosiyanasiyana yazitsulo. Chifukwa cha mankhwala ake apadera komanso mawonekedwe ake, amalembedwa ngati chitsulo chosankha kuposa zitsulo zina. Makamaka, aluminiyumu imadziwika ndi kulemera kwake kopepuka, mphamvu zokhalitsa, ductility kwambiri, magetsi ndi matenthedwe matenthedwe, komanso kukana kwambiri kutentha ndi ma radiation a nyukiliya.
Makhalidwe apaderawa atsegula njira yoti aluminiyamu azigwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Inasintha kayendetsedwe ka kayendetsedwe ka ndege ndipo imagwira ntchito yofunika kwambiri popanga ndege chifukwa katundu wake wopepuka amathandiza kuchepetsa kugwiritsira ntchito mafuta komanso kuchita bwino. Kuphatikiza apo, kulimba kwake komanso kusinthasintha kwake kumapangitsa kuti ikhale chinthu chabwino kwambiri chopangira ndege zolimba komanso zowuluka.
Kusinthasintha kwa aluminiyamu sikumangoyenda pandege, koma kumadutsa m'munda uliwonse. M'makampani opanga magalimoto, kugwiritsa ntchito aluminiyumu popanga magalimoto kwatchuka kwambiri. Chikhalidwe chopepuka chachitsulo chimapangitsa kuti mafuta azigwira bwino ntchito ndikuwonjezera magwiridwe antchito, pamapeto pake amathandizira mayendedwe okhazikika.
Kuphatikiza apo, matenthedwe ochititsa chidwi a aluminiyumu amathandizira kuti kutentha kutheke bwino, ndikupangitsa kuti ikhale yofunika kwambiri popanga masinki otentha pazida zamagetsi. Kuphatikiza pa conductivity, izi zimatsimikizira kuti zida zamagetsi zikuyenda bwino komanso moyenera, kupewa zovuta zomwe zingawotche.
Chinthu chinanso chodziwika bwino cha aluminiyumu ndi kukana kwa dzimbiri. Mosiyana ndi zitsulo zina zambiri, aluminiyumu imapanga kagawo kakang'ono koteteza oxide kakakhala ndi mpweya. Khalidweli limapangitsa kuti likhale loyenera kugwiritsidwa ntchito m'malo am'madzi chifukwa limatha kupirira kuwonongeka kwamadzi amchere ndi zinthu zosiyanasiyana.
Kuphatikiza apo, kubwezeretsedwanso kwa aluminiyumu komanso mphamvu zochepa zomwe zimafunikira kuti zichotsedwe zimapangitsa kukhala chisankho chokonda zachilengedwe. Ndi chidziwitso chowonjezereka cha chitukuko chokhazikika, kufunikira kwa aluminiyumu m'mafakitale osiyanasiyana kukukulirakulira. Kubwezeretsanso kwake kumachepetsa kufunika kopanga aluminiyamu yoyamba, kupulumutsa mphamvu komanso kuchepetsa mpweya wowonjezera kutentha.
Komabe, ngakhale pali zabwino zambiri, kupanga ndi kukonza aluminiyamu kumabweretsa zovuta zake. Kuchotsa aluminiyamu ku ore kumafuna mphamvu zambiri ndi chuma, zomwe zimapangitsa kuti mpweya wowonjezera kutentha utuluke. Kuphatikiza apo, migodi ikhoza kukhala ndi zotsatira zoyipa zachilengedwe, kuphatikizapo kuwononga malo okhala komanso kuwonongeka kwa nthaka.
Khama likuchitika kuti athane ndi mavutowa komanso kukonza zopangira aluminiyamu bwino. Kafukufuku ndi kakulidwe ka m'zigawo zokhazikika zikupitilira, monga kugwiritsa ntchito mphamvu zongowonjezwdwa ndi kukonzanso njira zobwezereranso kuti zichepetse kuwonongeka kwa chilengedwe.
Pomaliza, wapadera mankhwala ndi thupi katundu zotayidwa, kuphatikizapo kuwala kwake, mphamvu, ductility, magetsi ndi matenthedwe madutsidwe, kukana kutentha ndi kukana ma radiation, kupanga zosunthika ndi zofunika zitsulo m'mafakitale osiyanasiyana. Ntchito zake m'magawo monga ndege, magalimoto, zamagetsi ndi zombo zasintha mafakitalewa ndikuthandizira chitukuko chokhazikika. Kafukufuku wopitilira ndi zatsopano ndizofunikira kuti apititse patsogolo luso komanso kukhazikika kwa kupanga aluminiyamu ndikuwonetsetsa kuti phindu lake likupitilira kwa anthu.
