Ukushintshwa kwamandla kudonsa ukukhula kwesidingo se-aluminium, futhi u-Alcoa unethemba lokuthi amathemba emakethe ye-aluminium

Esitatimendeni somphakathi esisanda kwenzeka, uWilliam F. Oplinger, i-CEO ye-Alcoa, ezwakalise okulindelwe okulindelwe ekuthuthukisweni kwesikhathi esizayo kweImakethe ye-Aluminium. Uveze ukuthi ukusheshisa kwenguquko ye-Global Energy, isidingo se-aluminium njengoba izinto ezibalulekile zensimbi ziyaqhubeka zikhula, ikakhulukazi ngokwesimo sokushoda kwethusi. Njengomuntu obambele ithusi, i-aluminium ikhombisile amandla amakhulu kwezinye izimo zohlelo lokusebenza.

I-Oplinger igcizelele ukuthi inkampani inethemba elikhulu ngamathemba okuthuthuka kwesikhathi esizayo emakethe ye-aluminium. Ukholelwa ukuthi ukuguqulwa kwamandla kuyinto ebalulekile eshayela ukukhula kwesidingo se-aluminium. Ngokutshala imali ekhulayo emhlabeni jikelele kwamandla avuselelekayo kanye nobuchwepheshe obuphansi bekhabhoni,aluminiyamu, njengensimbi engashintshi elingashintshi, yokulwa nokuqina, futhi ikhombisa amathuba okusebenza abanzi emikhakheni ehlukahlukene efana namandla, ukwakhiwa, nokuhamba. Ikakhulu embonini yamandla, ukusetshenziswa kwe-aluminium emigqeni yokudlulisela kanye nabaguquli kukhula njalo, ukushayela ngokuqhubekayo ukukhula kwesidingo se-aluminium.

Oplinger futhi kushiwo ukuthi inkambiso ephelele ishayela i-aluminium isidingo sokukhula ngesilinganiso se-3%, 4%, noma i-5% njalo ngonyaka. Lesi silinganiso sokukhula sibonisa ukuthi imakethe ye-aluminium izogcina umfutho wokukhula oqinile eminyakeni ezayo. Uveze ukuthi lokhu kukhula akugcini nje ngokuqhutshwa yinguquko yamandla kuphela, kodwa futhi nangezinguquko ezithile zokuhlinzekwa embonini ye-aluminium. Lezi zinguquko, kufaka phakathi intuthuko yezobuchwepheshe, ukuthuthuka okuthuthukile kokukhiqiza, kanye nokuthuthukiswa kwezinsizakusebenza ezintsha ze-aluminium ore, kuzonikeza ukusekelwa okuqinile ekuthuthukisweni okuzayo kwemakethe ye-aluminium.

 
Nge-Alcoa, lo mkhuba ngokungangabazeki uletha amathuba amakhulu amabhizinisi. Njengomunye wabakhiqizi be-aluminium abahamba phambili emhlabeni, u-Alcoa uzokwazi ukubekezelela ngokuphelele izinzuzo zawo ecaleni embonini ye-aluminium ukuze ahlangabezane nesidingo semakethe semikhiqizo ephezulu ye-aluminium. Ngasikhathi sinye, inkampani izoqhubeka nokukhulisa ukulongela ucwaningo nokuthuthuka, ukukhuthaza ubuchwepheshe obusha kanye nokuvuselelwa komkhiqizo, ukuze uvumelane kangcono nezinguquko zemakethe kanye nezidingo zamakhasimende.
