Pehea e koho ai i kūpono no kā lākou mau mea alumini alumini, ʻo ke koho ʻana i ka brand alloy kahi hana nui, ʻO kēlā me kēia brand alloy kona haku mele ponoʻī ponoʻī, nā mea hoʻohui i hoʻohui ʻia e hoʻoholo i nā waiwai mechanical o ka alumini alloy conductivity corrosion resistance a pēlā aku.

Hiki ke loaʻa i kēlā me kēia mīkini alumini alumini i kona haku mele mele ma GB / T3190-2020.Line 1 he kiʻekiʻe ka lōʻihi conductivity elongation, 2 moʻo he kiʻekiʻe paʻakikī maikaʻi kuʻihao hana, 3 moʻo he maikaʻi anti-corrosion hana, elongation maikaʻi, 4 moʻo me ka haʻahaʻa. Hoʻohana nui ʻia ka helu hoʻoheheʻe no ka wili, 5 series alloy distribution ratio he nui, 6 series ikaika, ʻoi aku ka maikaʻi, ʻoi aku ka nui o ka ʻai ʻana i ka mākeke paʻakikī, ʻo 7 ka nui o ka hana kuʻihao paʻakikī kiʻekiʻe, no laila maʻamau. hoʻohana i nā ʻāpana ikaika kiʻekiʻe, I kēia manawa, ʻo nā noi mākeke o ka moʻo 8 ka mea nui i nā huahana alumini alumini.
