He mea whakarewa tata hiriwa-mā, he mārō, he ngāwari, he ferromagnetic te nikara, he tino orohia, ā, he ātete ki te waikura. He mea aroha ki te rino te nikara. Kei roto i te pūtake o te whenua te nikara, ā, he koranu nikara-rino tūturu. Ka taea te wehewehe i te nikara ki te nikara tuatahi me te nikara tuarua. Ko te nikara tuatahi e pā ana ki ngā hua nikara tae atu ki te nikara hikohiko, te paura nikara, ngā poraka nikara, me te nikara hydroxyl. Ka taea te whakamahi i te nikara parakore teitei hei hanga pākahiko lithium-ion mō ngā waka hiko; ko te nikara tuarua kei roto ko te nikara poaka rino me te nikara poaka rino, e whakamahia ana hei hanga maitai kore waikura. Ferronickel.
E ai ki ngā tatauranga, mai i te marama o Hūrae 2018, kua heke te utu o te nikara o te ao mā te neke atu i te 22%, ā, kua tino heke te mākete nikara ā-rohe o Shanghai, me te hekenga neke atu i te 15%. Ko ēnei hekenga e rua te mea tuatahi i waenga i ngā taonga o te ao me te whare. Mai i Mei ki Hune 2018, i whiua a Rusal e te United States, ā, i tumanako te mākete ka whai wāhi te nikara o Rūhia. I tua atu i ngā āwangawanga ā-rohe mō te korenga o te nikara e tukuna ana, he maha ngā āhuatanga i akiaki i ngā utu nikara kia eke ki te taumata teitei o te tau i te tīmatanga o Hune. Nō muri mai, nā te maha o ngā āhuatanga i pāngia ai, ka heke tonu ngā utu nikara. Ko te tumanako o te umanga mō ngā tūmanakohanga whanaketanga o ngā waka hiko hou kua tautoko i te pikinga o mua o ngā utu nikara. I tino tumanakohia te nikara i mua, ā, i eke te utu ki te taumata teitei maha-tau i te marama o Āperira o tēnei tau. Heoi, he āta haere te whanaketanga o te umanga motuka hiko hou, ā, me roa te wā ki te kohikohi i te tipu nui. Nā te kaupapa here tautoko hou mō ngā waka hiko hou i whakatinanahia i waenganui o Hune, e anga ana ki ngā tauira kaha-pūngao teitei, kua ringihia hoki te wai makariri ki runga i te tono nikara i roto i te mara pākahiko. Hei tāpiri, ko ngā koranu maitai kore waikura tonu te kaiwhakamahi mutunga o te nikara, neke atu i te 80% o te tono katoa i Haina. Heoi, ko te maitai kore waikura, e whakaatu ana i te tono nui, kāore i arahi i te wā tihi tuku iho o te "Golden Nine me te Silver Ten". E whakaatu ana ngā raraunga i te mutunga o Oketopa 2018, ko te taonga maitai kore waikura i Wuxi he 229,700 tana, he pikinga o te 4.1% mai i te tīmatanga o te marama me te pikinga tau-ki-te-tau o te 22%. . Nā te hekenga o ngā hoko whare motuka, he ngoikore te tono maitai kore waikura.
Ko te tuatahi ko te tuku me te tono, koinei te mea matua hei whakatau i ngā au o ngā utu mō te wā roa. I ngā tau tata nei, nā te whānui haere o te kaha whakaputa nikara ā-rohe, kua pāngia te mākete nikara o te ao e te nui o te tāpui, ā, ka heke tonu ngā utu nikara o te ao. Heoi, mai i te tau 2014, i te wā i panuitia ai e Indonesia, te kaihoko nikara nui rawa atu o te ao, te whakatinanatanga o te kaupapa here aukati kaweake nikara mata, kua piki haere ngā āwangawanga o te mākete mō te āputa o te tuku nikara, ā, kua hurihia e ngā utu nikara o te ao te au ngoikore o mua i roto i te kotahi te pakū. Hei tāpiri, me kite hoki tātou kua uru haere te hanga me te tuku ferronickel ki tētahi wā whakaora me te tipu. Heoi anō, kei te mau tonu te tukunga o te kaha whakaputa ferronickel e tumanakohia ana i te mutunga o te tau. Hei tāpiri, ko te kaha whakaputa nikara rino hou i Indonesia i te tau 2018 he tata ki te 20% teitei ake i te matapae o te tau o mua. I te tau 2018, ko te kaha whakaputa o Indonesia kei roto i te Tsingshan Group Phase II, Delong Indonesia, Xinxing Cast Pipe, Jinchuan Group, me Zhenshi Group. Ka tukuna ēnei kaha whakaputa, ā, ka kore e nui te tuku o te ferronickel i ngā wā kei te heke mai.
I roto i ngā kupu poto, he nui ake te pānga o te ngoikore o ngā utu nikara ki te mākete o te ao, ā, kāore i te rawaka te tautoko ā-rohe hei ārai i te hekenga. Ahakoa kei te mau tonu te tautoko pai mō te wā roa, kua pāngia hoki te mākete o nāianei e te ngoikore o te tono ā-rohe. I nāianei, ahakoa kei te mau tonu ngā āhuatanga pai matua, kua paku piki ake te taumaha poto, ā, kua puta ake he tukunga atu o te karo i ngā mōrearea whakapaipai nā te kaha haere o ngā āwangawanga nui. Kei te whakawhāiti tonu ngā kare ā-roto nui i te ia o ngā utu nikara, ā, ahakoa te kaha haere o ngā ohorere nui, kāore e ārai i te hekenga o te wāhanga. Ka puta he ia.
