ʻO Kina ka ʻāina me ka mea kiʻekiʻe loa o 6um-7um alumini foil ma ka honua. In 2009, ua hana ia ma mua o 150kt o ka alumini alumini i loko o kēia ʻano mānoanoa, ʻoi aku ma mua o 70kt i lawe ʻia i waho. I kēia manawa, ma mua o 90% ʻO ka 6um-7um alumini foil i hana ʻia ma ka mākeke kūloko 1235 huikau, a ua hoʻomaka kekahi mau mea hana ʻelua-zero foil e hoʻohana 8079 huikau, ʻoiai ke hoʻohana maʻamau nei nā mākeke ʻEulopa a me ʻAmelika 8079 huikau.

Ka huiʻana o nā ?1235 huikau a?8079 huikau ua like koe no ka mea o ka mea Fe. ʻO ka mea Fe maʻiʻo o 1235 ʻo ka huila 0.5-0.6, oiai kela o 8079 ʻo ka huila 0.85-0.95, a ʻo ka Si maʻiʻo o nā huila ʻelua 0.07-0.09.

Hoʻokumu ʻia nā billet e ka ingot hot rolling. Hoʻohana ʻia nā ʻāpana ʻelua i ke kaʻina homogenization ingot like, a olokaa aku 1+4 mea ʻōwili wela. ʻO 2.8mm-3mm ka mānoanoa o nā huahana hoʻopau wela.

I ke kaʻina ʻōwili anu, ua ʻōwili ʻia i ka mānoanoa o 0.28mm-0.30mm iloko 3 hala, a hoʻohana ʻia ke kaʻina hana annealing waena i ka wā e ʻōwili ai i ka mānoanoa o 0.5mm, i mea e loaʻa ai ka mānoanoa o 0.28mm-0.30mm i ka mokuʻāina H14. Waihona alumini. I ke kaʻina ʻōwili pepa, ua olokaa ia i 0.015mm-0.017mm iloko 3 hala, a laila ua pani ʻia nā ʻōwili, a ua hana ʻia kahi annealing waena haʻahaʻa haʻahaʻa, a ua like ke kaʻina hana annealing haʻahaʻa haʻahaʻa.

A laila e hoʻokō i ka holo hope o ka ʻōwili ʻana i ka mānoanoa o ka huahana i hoʻopau ʻia o 0.006mm-0.007mm. Ma hope o ka ʻoki ʻana i nā kikoʻī o ka huahana, lawe ʻia ka annealing huahana hope loa, no ka loaʻa ʻana o kahi pahu alumini degreased a maʻemaʻe i ka mokuʻāina О, a ʻo ke kaʻina hana annealing huahana hope loa o nā ʻāpana ʻelua ua like nō hoʻi.

(1) No ka 6um alumini pepa, ka helu awelika pinhole o 8079 ʻoi aku ka liʻiliʻi o ka alloy ma mua o ka 1235 huikau; ʻoi aku ka kiʻekiʻe o ka helu awelika o nā hopena haʻihaʻi i ke kaʻina o ka ʻōwili pepa ma mua o kēlā 1235 huikau. Ma keʻano o nā hōʻailona hana, ka awelika tensile ikaika o 8079 ʻoi aku ka nui o ka alloy ma mua o 10MPa ma mua o kēlā 1235 huikau, a ua oi iki ka elongation i ko 1235 huikau.

(2) No ka 7um alumini pepa, ka helu o nā ʻōpua o 8079 ʻoi aku ka liʻiliʻi o ka alloy ma mua o ka 1235 huikau, akā, ʻaʻole maopopo ka ʻokoʻa ma waena o lāua; ʻoiai ʻo ka helu awelika o nā hopena haʻihaʻi i ke kaʻina ʻōwili pepa ʻo ia nō 8079 ʻoi aku ka kiʻekiʻe o ka alloy ma mua o ka 1235 huikau. Ma keʻano o nā hōʻailona hana, aia ka maʻamau like me ka 6um alumini foil.
ʻO ka ʻokoʻa nui ma waena o ka 6um-7um alumini foil i hana ʻia e 1235 huikau a 8079 ʻo ka huila ʻo ia ka papa kuhikuhi hana o 8079 ʻoi aku ka kiʻekiʻe o ka alloy ma mua o ka 1235 huikau, a me ka helu o na pinholes o 6um alumini pepa i hanaia e 8079 ʻoi aku ka liʻiliʻi o ka alloy ma mua o ka 1235 huikau.
