Ingxenye eyodwa kwezingama-20 yobukhulu be-helipad

Siyifektri yobuchwepheshe bokucubungula i-aluminium, enikeza izixazululo ze-aluminium ngesikhathi esisodwa: Amandla e-aluminium emsulwa aphansi, kodwa ngokungeza izinto ezixubayo, amandla ayo kanye nokuqina kwayo kungathuthukiswa kakhulu, futhi izinhlobo ezahlukene ze-aluminium, njenge-aluminium eqinile, i-aluminium eqinile kakhulu, i-aluminium engagqwali kanye ne-aluminium ephothiwe, zingenziwa. I-aluminium kanye ne-alloy yayo inokumelana okuhle nokugqwala, ikakhulukazi ifilimu ye-oxide ebusweni bayo, engagcini nje ngokumelana nokugqwala, kodwa futhi inokushisa okuthile. Ngenxa yamandla ayo aphezulu, ubuningi obuphansi kanye nokumelana okuhle nokugqwala, i-aluminium alloy isetshenziswa kabanzi ekwakhiweni kwezimoto zezindiza njengezindiza namarokhethi.
