Soseji chikafu chinobatika zvakanyanya muhupenyu hwedu hwezuva nezuva, anogona kudyiwa zvakananga kana kuwedzerwa kune zvimwe zvekudya kuti uwedzere kuravira, asi iwe unoziva here kuti sei magumo maviri emasoseji akavharirwa nealuminium zvimedu?
Chekutanga, inonyanya kupikisa oxidation uye corrosion.Aluminium oxide inodzivirira firimu inowanzoumbwa pamusoro pezvigadzirwa zvealuminium.Iyo firimu inoshandiswa kuparadzanisa zvokudya uye kazhinji haisununguri zvinhu zvinokuvadza.Nekudaro, haina kukodzera kuchengetwa kwenguva refu kweasidhi uye alkaline chikafu newaini.Panguva imwecheteyo, inodzivirira chikafu kubva pakuita nemhepo nekuda kwekubuda kwemhepo, kudzivisa kuchinja kwekunhuhwirira kwechikafu uye zvimwe zvisingadiwi.
Chechipiri,simba uye kuoma zvinogona kusvika mwero, uye hazvisi nyore kutyora.Panguva imwecheteyo, ine ductility yakanaka uye inogona kuitwa yakaonda, kuchengetedza zvinhu uye kuderedza uremu.
Chetatu, mutengo wakaderera.Aluminium ine low density uye isimbi inogona kudzokororwa nyore nyore ine kukosha kwepamusoro pane simbi.Inogona kuwana kutenderera kwakanaka uye kudzivirira tsvina.Kana yakatsiviwa nezvigadzirwa zvepurasitiki, imwe haina simba rakakwana, uye imwe yacho haigoni kushandiswa zvakare uye yakaoma kuderedza, izvo zvinozokonzera kusvibiswa kwakanyanya.
Zvigadzirwa zvemasoseji zvinowanzo cylindrical, pane kurongedza.Iyo yekurongedza ine imwe yekupisa shrinkage rate uye inotaridzika zvakanyanya kunaka, saka hapana akawanda akawandisa ekuisa chisimbiso sarudzo.
Semugadziri wemidziyo yechikafu, zvekurongedza zvekushandisa zvakare zvigadzirwa zvedu.Isu tinopa mhando dzakasiyana uye modhi dzemakomputa, ayo akakodzera U-akaumbwa nemichina yekuchekeresa, otomatiki kaviri yekuchekera michina, uye zvimwe zvekuvharisa.Nemhando yepamusoro-soro yealuminium, yakazara kutsanangurwa, uye mutengo-unoshanda.
