ʻO kekahi o nā kinikini alumini extruded extruded a me ko lākou ʻano

He aha nā ʻano o kekahi o nā kinikini alumini extruded extruded? E hāhai i ka Kukuna alumini extrusion hale hana e aʻo hou:

(1) 1035 kinikini.

ʻO ka 1035 alloy he alumini maʻemaʻe ʻoihana me ka liʻiliʻi ma lalo o 0.7% impurities, ma waena o ka hao a me ka silikone ka nui o nā impurities. Hiki i ka ironona a me ka silikona a me kekahi mau mea hao ke hoʻonui i ka ikaika, akā e hoʻoliʻiliʻi nui i ka plasticity a me ka conductivity o ke kinikini.

ʻO ke aluminika maʻemaʻe kūleʻa kahi kūpaʻa kemika kiʻekiʻe i nā pāpāho he nui, ʻoi aku ke kiʻekiʻe ma mua o nā metala ʻē aʻe me ka hiki kiʻekiʻe.

ʻO ka liʻiliʻi o nā haumia i loko o ka alumini (ʻo ia hoʻi ka hao a me ka silikone), ʻo ke kiʻekiʻe o kāna kūpaʻa kūpale. ʻO ka ʻoiaʻiʻo, ʻo ka magnesium a me ka manganese wale nō e hōʻemi ʻole i ke kūpaʻa o ka alumini.

Hāʻawi ʻia nā huahana i hana ʻia me ka hapalua o ka 1035 ma lalo o ke annealing a me ka extrusion wela. Eia nō naʻe, me ka nānā ʻole i ke kūlana o ka lako, ʻo ke kaʻina hana hope loa o ka ʻikepili extruded kahi hoʻopololei, a hiki ke hoʻoponopono ʻia i ka mīkini ʻōwili. hoʻomaikaʻi iki ka waiwai ikaika, akā hoʻemi nui ka plasticity.

Hoʻohui ʻia, hoʻomaikaʻi iki ʻia ka uila uila o ke kinikini i ka wā anuanu. No laila, ke koʻikoʻi nā koi hana profile, pono e noʻonoʻo i nā loli o ka hana i luna ke hoʻoponopono.

Ke hoʻonui ʻia ka mahana, piʻi nui ka ikaika a me ka plasticity o ke aniani 1035. Ke hele ka mahana ma lalo o ka ʻole, e hoʻomaikaʻi nui ʻia ka ikaika a me nā pono ʻili.

(2) 3 a21 oka hao.

ʻO Alloy 3A21 kahi kinikini deformed i loko o ka ʻōnaehana binary AlMn. He kūpaʻa kūpale kiʻekiʻe a aneane like ia me ke aniani 1035. Kūpono kūpono nā huahana semi-pau o ke kinikini 3A21 no ka wili kinoea, kuʻihao hydrogen, kuʻihao arc argon a Hoʻokaʻaʻike kūpale o ka Weld mea like me ka metala kumu. He hana deformation maikaʻi ke kinikini i nā moku anuanu a me nā wela, a ākea ka laulā o ka mahana o ka hoʻololi wela (320 ~ 470C). ʻAʻole hiki i ke kinikini ke hoʻohui. e hoʻoikaika ʻia e ka mālama ʻana i ka wela a hoʻolako ʻia nā ʻikepili alloy i kahi annealed a extruded state paha.

ʻO ka hopena o ka mahana deformation a me ka wikiwiki deformation ma ke kūpaʻa deformation o 3A21 mea hoʻoheheʻe ʻoi aku ka liʻiliʻi ma mua o ka ʻoihana alumini maoli.

(3) 6063 oka hao.

Ma ke ʻano he lunamakaʻāinana o ke a1-mg-si alloy, ʻo ka alloy 6063 kahi extrudability maikaʻi a me ka weldability, a ʻo ia ka mea i makemake ʻia no ke kūkulu ʻana i Windows a me nā puka. Kuhi ʻia e ka plasticity kiʻekiʻe a me ke kūpaʻa o ka popopo ma lalo o ke ʻano o ka mahana a me ka wikiwiki o ka mīkini kaomi. .No stress corrosion tendency. I ka wā kuʻihao, ʻaʻole e emi maoli ke kūpaʻa o ka ʻaukā.

Hoʻoikaika ikaika ʻia ke kinikini 6063 i ka wā o ka mālama ʻana i ka wela. ʻO nā ʻaoʻao hoʻoikaika nui i ke kinikini ʻo MgSi a me AlSiFe. Inā ʻo ka ikaika o ka 6063 alloy extruded profiles he 98 ~ 117.6mpa i ka hoʻohui ʻāina, hiki ke hoʻonui ʻia ka ikaika i 176.4 ~ 196MPa ma hope o ke kinai a me ka ʻelemakule kūlohelohe. I kēia manawa, hoʻemi iki ka elongation pili (mai 23% ~ 25% a 15% ~ 20%). Ma hope o ka ʻelemakule ʻelemakule ma 160 ~ 170 ℃, hiki i ke kinikini ke loaʻa kahi hopena hoʻoikaika hou aʻe. I kēia manawa, hoʻonui ʻia ka ikaika o ka ikaika i 269.5 ~ 235.2MPa. Eia nō naʻe, i ka ʻelemakule kūpaka, ua hoʻēmi nui nā mea palaka (= 10% ~ 12%).

ʻO ka manawa ma waena o ka kinai ʻana a me ka ʻelemakule ʻepekema i kahi hopena koʻikoʻi i ke kēkelē hoʻoikaika o 60loy alloy (i ka ʻelemakule ʻelemakule). Me ka hoʻonui ʻana o ka manawa manawa mai 15min a 4h, hoʻemi ka ikaika a me ka ikaika i 29.4 ~ 39.2MPa. ʻAʻohe hopena koʻikoʻi o ka manawa hoʻokiwikā wela i nā pono mīkini o 6063 huahana hoʻoiho hapa.

(4) 6 pehea a02 oka a.

ʻO ke kinikini 6A02 maʻamau (me ka palena ʻole o ka ʻike keleawe) no ka a1-mg-si-cu series alloy. He kiʻekiʻe loa ia i nā pono lula ma nā kūlana o ka wikiwiki o ka mīkini hana a me ka mahana o ka lumi.

I ka hana ʻana o 6A02 oka a extruded semi-hoʻopau huahana, ʻoiai he ʻuʻuku kāna ʻike manganese, akā ma hope o ka mālama ʻana i ka wela hiki ʻole ke mālama i kahi hanana i kūkulu hou ʻia, no laila, hiki ke hoʻomaikaʻi maikaʻi i ka hana o ka ikaika. E like me ke kinikini 6063, wikiwiki ke oka 6A02 hoʻoikaika ʻia i ka wā o ka mālama ʻana i ka wela, a ʻo kāna mau hana hoʻoikaika paʻa Mg2Si a me W (AlxMg5Si4Cu).

Hiki ke hoʻonui ʻia ka ikaika o ka luhi e ka ʻelemakule kūlohelohe ma hope o ke kinai ʻana, kahi i ʻoi aku ka kiʻekiʻe ma mua o ka annealing, a ma kahi o ʻelua mau manawa ke kiʻekiʻe aʻe ma lalo o ka ʻelemakule hana ma hope o ke kinai ʻana. Eia nō naʻe, i ka ʻelemakule hana, ua emi ka waiwai o ka plastic. hoʻemi ʻia ma kahi o 1/2, a ua hoʻemi ʻia ka compression e ʻoi aku ma mua o 2/3).

ʻOkoʻa ke kinikini 6A02 mai ke aniani 6063. ʻO ke kinikini 6063 kahi kūpaʻa kūpale kiʻekiʻe i ke kūlana ʻelemakule kūlohelohe a me ke kūlana ʻelemakule kūlohelohe, ʻoiai ke kūpaʻa o ke kūpikipiki o ke aniani 6A02 e ʻike maopopo a ʻike ʻia ke ʻano o ka corrosion intercrystalline.

I ke kaʻina hana hoʻowali, i ka hoʻonui ʻana o ka ʻike keleawe i ke kinikini, hoʻonui ʻia ka ikaika o ka nalo ikaika. ʻO kahi laʻana, inā he 0.26% ke keleawe, ma hope o 6 mau mahina o ka hoʻāʻo ʻana (splashing with 30% NaCl solution), e hoʻoliʻiliʻi ka ikaika o ke kinikini e 25%, ʻoiai e emi ana kona elongation 90%. No laila, i hoʻomaikaʻi i ka ʻaʻai kūpikipiki, ʻo ka ʻike keleawe i ke kinikini ke kāohi pinepine ʻia ma mua o 0.1%.

Hiki ke ʻike pono ʻia ke kinikini 6A02, wili a wili ʻia a me ka arc argon welded. ʻO ka ikaika o ka ami i hoʻohui ʻia he 60% ~ 70% o kēlā me ka metala matrix. Ma hope o ke kinai ʻana a me ka ʻelemakule, hiki i ka ikaika o ka ami welded ke piʻi i 90% ~ 95% o kēlā o ka hao metala.

(5) 5 a06 kinikini.

ʻO ke kinikini 5A06 no ke kaʻina al-mg-mn. He plastic ia i ka mahana o ka lumi a me nā mahana kiʻekiʻe, a kūpaʻa nui i ka pala i nā ʻano media, e like me ka wai kai. ʻO ke kūpaʻa kūpale maikaʻi a me ka hiki ke hoʻopaʻa ʻia o ke kinikini e hoʻonui ākea. hoʻohana ʻia i ka ʻoihana moku. ʻO ka weld o ke kinikini he ikaika kiʻekiʻe a me ka waiwai lula. Ma ke ana wela o ka lumi, hiki i ka ikaika o ka ami welded ke piʻi i 90% ~ 95% o kēlā me ka metric matrix.

ʻO ka mea i luna ka hoʻolaha o kekahi o nā alloys alumini extruded extruded a me ko lākou ʻano. He a mākou nā hui extrusion alumini maʻamau, hiki ke hāʻawi: extrusion alumini extrusion, extrusion alumini extrusion a me nā lawelawe ʻana i hana pilikino ʻia, ʻoluʻolu e nīnau
