Dukurikije amakuru aheruka gutumizwa no kohereza mu mahanga yashyizwe ahagaragara n’ubuyobozi bukuru bwa gasutamo y’Ubushinwa, Ubushinwa bwageze ku iterambere rikomeye muri aluminiyumu idakozwe kandiibicuruzwa bya aluminium, umucanga wa aluminiyumu hamwe na hamwe, hamwe na oxyde ya aluminium muri Mata, byerekana umwanya w’Ubushinwa ku isoko rya aluminium ku isi.

 
Ubwa mbere, kwinjiza no kohereza ibintu hanze ya aluminiyumu na aluminiyumu. Ukurikije amakuru, kwinjiza no kohereza hanze ya aluminium idakoreshwa kandiibikoresho bya aluminiumyageze kuri toni 380000 muri Mata, umwaka-mwaka wiyongereyeho 72.1%. Ibi byerekana ko Ubushinwa busaba n'ubushobozi bwo gukora ku isoko rya aluminiyumu ku isi byombi byiyongereye. Muri icyo gihe, umubare w’ibicuruzwa byatumijwe mu mahanga n’ibyoherezwa mu mahanga kuva muri Mutarama kugeza muri Mata na byo byageze ku iterambere ry’imibare ibiri, bigera kuri toni miliyoni 1.49 na toni miliyoni 1.49, umwaka ushize wiyongereyeho 86,6% na 86,6%. Aya makuru yemeza kandi imbaraga zikomeye zo gukura kw'isoko rya aluminium y'Ubushinwa.

 
Icya kabiri, ibintu bitumizwa mu mahanga byumucanga wa aluminiyumu hamwe na hamwe. Muri Mata, ibicuruzwa byatumizwaga mu bucukuzi bw'amabuye ya aluminiyumu no kwibanda mu Bushinwa byari toni 130000, umwaka ushize wiyongereyeho 78.8%. Ibi byerekana ko Ubushinwa bukeneye umucanga wa aluminiyumu bugenda bwiyongera kugirango bushyigikire umusaruro wa aluminium. Hagati aho, ibicuruzwa byatumijwe mu mahanga kuva muri Mutarama kugeza muri Mata byari toni 550000, umwaka ushize wiyongereyeho 46.1%, ibyo bikaba byerekana ko ubukungu bw’isoko rya aluminiyumu ryiyongera.

 
Byongeye kandi, ibyoherezwa mu mahanga bya alumina binagaragaza kuzamura ubushobozi bwa aluminium y'Ubushinwa. Muri Mata, ibicuruzwa byoherezwa mu mahanga bya alumina biva mu Bushinwa byari toni 130000, umwaka ushize byiyongereyeho 78.8%, ibyo bikaba bihwanye n’ubwiyongere bw’ibicuruzwa biva mu mahanga bya aluminium. Ibi birerekana kandi ko Ubushinwa burushanwe mubijyanye n’umusaruro wa alumina. Hagati aho, ibicuruzwa byoherezwa mu mahanga kuva muri Mutarama kugeza muri Mata byari toni 550000, umwaka ushize byiyongereyeho 46.1%, ibyo bikaba bihwanye n’ikigereranyo cyo kwiyongera kw’ibicuruzwa biva mu mahanga by’umucanga wa aluminiyumu, byongeye kugenzura ko iterambere ryiyongera rya alumina isoko.

 
Duhereye kuri aya makuru, birashobora kugaragara ko isoko rya aluminium y'Ubushinwa ryerekana imbaraga zikomeye zo gukura. Ibi bishyigikirwa no kuzamuka kw’ubukungu bw’Ubushinwa no gutera imbere mu buryo burambye bw’inganda zikora inganda, ndetse no gukomeza kuzamura ubushobozi bw’Ubushinwa ku isoko rya aluminium ku isi. Ubushinwa ni umuguzi w'ingenzi, butumiza mu mahanga ibikoresho byinshi bya aluminiyumu n'amabuye ya aluminiyumu kugira ngo bikemure inganda zikora; Muri icyo gihe, ni n’umugurisha w'ingenzi ugira uruhare mu marushanwa yo ku isoko rya aluminiyumu ku isi yohereza ibicuruzwa hanze ya aluminiyumu, ibikoresho bya aluminiyumu, n'ibicuruzwa bya aluminium. Uburinganire bwubucuruzi bufasha kubungabunga umutekano ku isoko rya aluminiyumu ku isi kandi biteza imbere ubufatanye mu bukungu hagati y’ibihugu.
