Ke alakaʻi ʻia e nā kumu kūʻai mākeke ikaika a me ka ulu wikiwiki ʻana o ka noi i ka ʻoihana ikehu hou, ʻo Shanghaimākeke alumini no ka wā e hiki mai anaua hōʻike i kahi ʻano piʻi i ka Pōʻakahi, Mei 27th. Wahi a ka ʻikepili mai ka Shanghai Futures Exchange, ua piʻi ka aelike alumini ʻoi loa o Iulai i ka 0.1% i ke kālepa ʻana i kēlā me kēia lā, me nā kumukūʻai e piʻi ana i 20910 yuan no ton. ʻAʻole mamao kēia kumukūʻai mai ka kiʻekiʻe ʻelua makahiki o 21610 yuan i pā i ka pule i hala.

Hoʻonui nui ʻia ka piʻi ʻana o nā kumukūʻai alumini e nā kumu nui ʻelua. ʻO ka mea mua, ʻo ka hoʻonui ʻana i ke kumukūʻai o ka alumina e hāʻawi i ke kākoʻo ikaika no nā kumukūʻai alumini. Ma ke ʻano he kumu kumu nui o ka alumini, ʻo ke kumu kūʻai o ka alumini oxide e pili pono i ke kumu kūʻai o ka alumini. I kēia mau lā, ua piʻi nui ke kumukūʻai o nā ʻaelike alumina, me ka piʻi nui o 8.3% i ka pule i hala. ʻOiai he 0.4% hāʻule i ka Pōʻakahi, ke kū nei ke kumukūʻai no ke ton ma kahi kiʻekiʻe o 4062 yuan. Hoʻouna pololei ʻia kēia hoʻonui kumukūʻai i nā kumukūʻai alumini, e ʻae ana i nā kumukūʻai alumini e hoʻomau i ka ikaika ma ka mākeke.

ʻO ka lua, ʻo ka ulu wikiwiki ʻana o ka ʻoihana ikehu hou ua hāʻawi pū i ka mea nui i ka piʻi ʻana o nā kumukūʻai alumini. Me ka manaʻo nui o ka honua i ka ikehu maʻemaʻe a me ka hoʻomohala hoʻomau, ke piʻi mau nei ka noi no nā kaʻa ikehu hou a me nā huahana ʻē aʻe. ʻO Aluminum, ma ke ʻano he mea māmā, loaʻa nā manaʻo hoʻohana ākea i nā kula e like me nā kaʻa ikehu hou. ʻO ka ulu ʻana o kēia koi ua hoʻokomo i ka ikaika hou i ka mākeke alumini, e hoʻonui ana i nā kumukūʻai alumini.

Hōʻike pū ka ʻikepili kālepa o ka Shanghai Futures Exchange i ke ʻano ikaika o ka mākeke. Ma waho aʻe o ka piʻi ʻana o nā ʻaelike alumini e hiki mai ana, ua hōʻike pū nā ʻano metala ʻē aʻe i nā ʻano like ʻole. Ua hāʻule ke keleawe o Shanghai i ka 0.4% i ka 83530 yuan no ke tona; Ua hāʻule ʻo Shanghai tin i ka 0.2% i ka 272900 yuan no ke tona; Ua piʻi ka nickel Shanghai i ka 0.5% i ka 152930 yuan no ke tona; Ua piʻi ka zinc o Shanghai i ka 0.3% i ka 24690 yuan no ke tona; Ua piʻi ke alakaʻi o Shanghai i ka 0.4% i ka 18550 yuan no ke tona. Hōʻike ke kumukūʻai o kēia mau ʻano metala i ka paʻakikī a me ka ʻokoʻa o ka hoʻolako ʻana i ka mākeke a me nā pilina koi.

ʻO ka holoʻokoʻa, ka piʻi ʻana o ka Shanghaimākeke kūʻai aluminiua kākoʻo ʻia e nā kumu like ʻole. ʻO ka piʻi ʻana o nā kumukūʻai maka a me ka ulu wikiwiki ʻana o ka ʻenehana ikehu hou ua hāʻawi i ke kākoʻo ikaika no nā kumukūʻai alumini, ʻoiai e hōʻike ana i nā manaʻolana o ka mākeke no ka wā e hiki mai ana o ka mākeke alumini. Me ka hoʻihoʻi lohi ʻana o ka hoʻokele honua a me ka hoʻomohala wikiwiki ʻana o ka ikehu hou a me nā māla ʻē aʻe, manaʻo ʻia ka mākeke alumini e hoʻomau i ka piʻi ʻana i luna.
