I-Aluminium (Al) iyikhemikhali enenombolo ye-athomu 13. Iyingxenye yesithathu egcwele kakhulu oqweqweni loMhlaba, ehlanganisa mayelana 8% yesisindo sayo. I-elementi yaqala ukuhlukaniswa phakathi 1825 isazi sefiziksi saseDenmark u-Hans Christian Ørsted. Ngenxa ye-reactivity yayo ephezulu, i-aluminium ayivamile ukutholakala ngesimo sayo esihlanzekile; esikhundleni salokho, ivame ukutholakala kumaminerali afana ne-bauxite, lapho ikhishwa khona.

Izakhiwo ze-aluminium ziyenza intandokazi ezimbonini ezahlukahlukene. Nasi isifinyezo sezici zayo ezibalulekile:
Impahla | Incazelo |
I-Ductility | Ingadonselwa izintambo ezincane |
Ukumelana Nokugqwala | Yakha isendlalelo se-oxide esivikelayo |
Ukonakala | Ingakhandwa ibe amashidi amancane |
I-Thermal Conductivity | Umqhubi omuhle wokushisa |
I-Electric Conductivity | I-conductor enhle kagesi |
Ukuminyana | 2.71 g/cm³, cishe ingxenye eyodwa kwezintathu yensimbi |
Ukubukeka | Phezulu, iwusizo ezibukweni kanye nopende olukhanyayo |
I-Aluminium iza ngezindlela ezihlukahlukene, ngayinye inezinhlelo zokusebenza ezithile:
Uhlobo | Incazelo | Ukusetshenziswa Okuvamile |
I-Aluminium Ehlanzekile | Ifomu elihlanzekile, ethambile, i-ductile, conductive, ukumelana nokugqwala | Izintambo, izintambo, ucwecwe |
Ama-aluminium Alloys | Ingxube ye-aluminium nezinye izakhi ukuze uthole amandla angeziwe nobulukhuni | Izinjini, amaphiko endiza, imikhiqizo yabathengi |
I-Aluminium yokusakaza | Ama-alloys athululelwa isikhunta ukuze enze izingxenye, engabizi kakhulu kodwa i-ductile encane | Izingxenye ezikhiqizwe ngobuningi |
I-aluminium eyenziwe | Kucutshungulwe ngokugoqeka, ukuqamba, noma i-extrusion, iqinile futhi ifanele izinhlelo zokusebenza ezihlukahlukene | Izingxenye zemoto, izingxenye ze-aerospace |
I-Anodized Aluminium | Kwelashwe nge-electrochemically ukuze kutholwe umbala kanye nokwanda kokuqina | Imikhiqizo yezokwakha, izinto zikagesi zasendlini |
I-Aluminium egcwele | Ukumelana nokugqwala okuthuthukisiwe ngezendlalelo ezengeziwe ze-aluminium noma i-alloy | Ezezimoto, ujantshi, izinhlelo zokusebenza ze-aerospace |
Ukuhlukahluka kwe-aluminium kubonakala ezinhlobonhlobo zezinhlelo zokusebenza:
Imboni | Izinhlelo zokusebenza |
I-Aerospace | Izingxenye zezindiza, amaphiko, i-fuselage |
Ezezimoto | Izinjini, imizimba yezimoto, amasondo |
Osolwandle | Ama-Hulls, izinsika, nezinye izingxenye zomkhumbi |
Ukupakisha | Amathini esiphuzo, ucwecwe |
Ukwakha | Izakhiwo zokwakha, amafasitela, iminyango, uhlangothi, izintambo |
Izinto zikagesi | Izintambo zamandla, Izimpondo ze-TV, izitsha zesathelayithi |
Izimpahla Zabathengi | Izinto zokupheka, amacala e-smartphone, amalaptop, Ama-TV |
Imishini Yezokwelapha | Izihlalo ezinamasondo, izinsimbi zokuhlinza, abahambahambayo, izinduku |
Ukusebenza nge-aluminium kunobuhle nobubi bakho:
Izinzuzo | Ukubi |
Engasindi | Ayinamandla njengensimbi |
Ukumelana nokubola | Izindleko eziphezulu kunamanye amapulasitiki |
High conductivity ezishisayo kanye kagesi | Ukushisela kungaba inselele ngenxa yokushisa okuphezulu okuholela ekuqinisweni okusheshayo kwama-welds |
100% isebenziseka kabusha | Amanye ama-alloys asezingeni eliphezulu angabiza |
Isidingo somhlaba wonke se-aluminium siqhutshwa izinto zayo ezingasindi neziqinile, okwenza kube kuhle ezinhlelweni ezahlukene. Imboni ilokhu ithuthuka, ngamasu amasha ezindleleni zokukhiqiza kanye nobuchwepheshe bokugaywa kabusha.
Ukukhiqizwa kwe-aluminium kuhilela ukumba i-bauxite yezimayini, ukuyicwenga ku-alumina, bese uyincibilikisa ukuze ikhiqize i-aluminium emsulwa. Inqubo ye-Hall-Héroult iyindlela ehamba phambili esetshenziswa namuhla.
I-aluminium 100% isebenziseka kabusha, futhi ukugaywa kabusha konga kuze kube 95% wamandla adingekayo ukukhiqiza i-aluminium entsha ngezinto ezingavuthiwe. Lokhu kwenza ukugaywa kabusha kube yingxenye ebalulekile yemboni.
Njengoba izimboni zifuna izinto zokwakha ezilula neziqinile, isidingo se-aluminium kulindeleke ukuthi sikhule. Ukuqamba okusha ekuthuthukisweni kwe-alloy nezindlela zokucubungula kuzokwandisa ukusetshenziswa kwayo.
