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

(1) 1035 kinikini.

?O ka 1035 alloy he alumini ma?ema?e ?oihana me ka li?ili?i 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 ho?onui i ka ikaika, akā e ho?oli?ili?i nui i ka plasticity a me ka conductivity o ke kinikini.

?O ke aluminika ma?ema?e kūle?a kahi kūpa?a kemika ki?eki?e i nā pāpāho he nui, ?oi aku ke ki?eki?e ma mua o nā metala ?ē a?e me ka hiki ki?eki?e.

?O ka li?ili?i o nā haumia i loko o ka alumini (?o ia ho?i ka hao a me ka silikone), ?o ke ki?eki?e o kāna kūpa?a kūpale. ?O ka ?oia?i?o, ?o ka magnesium a me ka manganese wale nō e hō?emi ?ole i ke kūpa?a o ka alumini.

Hā?awi ?ia nā huahana i hana ?ia me ka hapalua o ka 1035 ma lalo o ke annealing a me ka extrusion wela. Eia nō na?e, me ka nānā ?ole i ke kūlana o ka lako, ?o ke ka?ina hana hope loa o ka ?ikepili extruded kahi ho?opololei, a hiki ke ho?oponopono ?ia i ka mīkini ?ōwili. ho?omaika?i iki ka waiwai ikaika, akā ho?emi nui ka plasticity.

Ho?ohui ?ia, ho?omaika?i iki ?ia ka uila uila o ke kinikini i ka wā anuanu. No laila, ke ko?iko?i nā koi hana profile, pono e no?ono?o i nā loli o ka hana i luna ke ho?oponopono.

Ke ho?onui ?ia ka mahana, pi?i nui ka ikaika a me ka plasticity o ke aniani 1035. Ke hele ka mahana ma lalo o ka ?ole, e ho?omaika?i nui ?ia ka ikaika a me nā pono ?ili.

(2) 3 a21 oka hao.

?O Alloy 3A21 kahi kinikini deformed i loko o ka ?ōnaehana binary AlMn. He kūpa?a kūpale ki?eki?e a aneane like ia me ke aniani 1035. Kūpono kūpono nā huahana semi-pau o ke kinikini 3A21 no ka wili kinoea, ku?ihao hydrogen, ku?ihao arc argon a Ho?oka?a?ike kūpale o ka Weld mea like me ka metala kumu. He hana deformation maika?i ke kinikini i nā moku anuanu a me nā wela, a ākea ka laulā o ka mahana o ka ho?ololi wela (320 ~ 470C). ?A?ole hiki i ke kinikini ke ho?ohui. e ho?oikaika ?ia e ka mālama ?ana i ka wela a ho?olako ?ia nā ?ikepili alloy i kahi annealed a extruded state paha.

?O ka hopena o ka mahana deformation a me ka wikiwiki deformation ma ke kūpa?a deformation o 3A21 mea ho?ohehe?e ?oi aku ka li?ili?i ma mua o ka ?oihana alumini maoli.

(3) 6063 oka hao.

Ma ke ?ano he lunamaka?āinana o ke a1-mg-si alloy, ?o ka alloy 6063 kahi extrudability maika?i a me ka weldability, a ?o ia ka mea i makemake ?ia no ke kūkulu ?ana i Windows a me nā puka. Kuhi ?ia e ka plasticity ki?eki?e a me ke kūpa?a o ka popopo ma lalo o ke ?ano o ka mahana a me ka wikiwiki o ka mīkini kaomi. .No stress corrosion tendency. I ka wā ku?ihao, ?a?ole e emi maoli ke kūpa?a o ka ?aukā.

Ho?oikaika ikaika ?ia ke kinikini 6063 i ka wā o ka mālama ?ana i ka wela. ?O nā ?ao?ao ho?oikaika nui i ke kinikini ?o MgSi a me AlSiFe. Inā ?o ka ikaika o ka 6063 alloy extruded profiles he 98 ~ 117.6mpa i ka ho?ohui ?āina, hiki ke ho?onui ?ia ka ikaika i 176.4 ~ 196MPa ma hope o ke kinai a me ka ?elemakule kūlohelohe. I kēia manawa, ho?emi iki ka elongation pili (mai 23% ~ 25% a 15% ~ 20%). Ma hope o ka ?elemakule ?elemakule ma 160 ~ 170 ℃, hiki i ke kinikini ke loa?a kahi hopena ho?oikaika hou a?e. I kēia manawa, ho?onui ?ia ka ikaika o ka ikaika i 269.5 ~ 235.2MPa. Eia nō na?e, i ka ?elemakule kūpaka, ua ho?ēmi nui nā mea palaka (= 10% ~ 12%).

?O ka manawa ma waena o ka kinai ?ana a me ka ?elemakule ?epekema i kahi hopena ko?iko?i i ke kēkelē ho?oikaika o 60loy alloy (i ka ?elemakule ?elemakule). Me ka ho?onui ?ana o ka manawa manawa mai 15min a 4h, ho?emi ka ikaika a me ka ikaika i 29.4 ~ 39.2MPa. ?A?ohe hopena ko?iko?i o ka manawa ho?okiwikā wela i nā pono mīkini o 6063 huahana ho?oiho hapa.

(4) 6 pehea a02 oka a.

?O ke kinikini 6A02 ma?amau (me ka palena ?ole o ka ?ike keleawe) no ka a1-mg-si-cu series alloy. He ki?eki?e 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 ?ana o 6A02 oka a extruded semi-ho?opau huahana, ?oiai he ?u?uku kāna ?ike manganese, akā ma hope o ka mālama ?ana i ka wela hiki ?ole ke mālama i kahi hanana i kūkulu hou ?ia, no laila, hiki ke ho?omaika?i maika?i i ka hana o ka ikaika. E like me ke kinikini 6063, wikiwiki ke oka 6A02 ho?oikaika ?ia i ka wā o ka mālama ?ana i ka wela, a ?o kāna mau hana ho?oikaika pa?a Mg2Si a me W (AlxMg5Si4Cu).

Hiki ke ho?onui ?ia ka ikaika o ka luhi e ka ?elemakule kūlohelohe ma hope o ke kinai ?ana, kahi i ?oi aku ka ki?eki?e ma mua o ka annealing, a ma kahi o ?elua mau manawa ke ki?eki?e a?e ma lalo o ka ?elemakule hana ma hope o ke kinai ?ana. Eia nō na?e, i ka ?elemakule hana, ua emi ka waiwai o ka plastic. ho?emi ?ia ma kahi o 1/2, a ua ho?emi ?ia ka compression e ?oi aku ma mua o 2/3).

?Oko?a ke kinikini 6A02 mai ke aniani 6063. ?O ke kinikini 6063 kahi kūpa?a kūpale ki?eki?e i ke kūlana ?elemakule kūlohelohe a me ke kūlana ?elemakule kūlohelohe, ?oiai ke kūpa?a o ke kūpikipiki o ke aniani 6A02 e ?ike maopopo a ?ike ?ia ke ?ano o ka corrosion intercrystalline.

I ke ka?ina hana ho?owali, i ka ho?onui ?ana o ka ?ike keleawe i ke kinikini, ho?onui ?ia ka ikaika o ka nalo ikaika. ?O kahi la?ana, inā he 0.26% ke keleawe, ma hope o 6 mau mahina o ka ho?ā?o ?ana (splashing with 30% NaCl solution), e ho?oli?ili?i ka ikaika o ke kinikini e 25%, ?oiai e emi ana kona elongation 90%. No laila, i ho?omaika?i i ka ?a?ai kūpikipiki, ?o ka ?ike keleawe i ke kinikini ke kāohi pinepine ?ia ma mua o 0.1%.

Hiki ke ?ike pono ?ia ke kinikini 6A02, wili a wili ?ia a me ka arc argon welded. ?O ka ikaika o ka ami i ho?ohui ?ia he 60% ~ 70% o kēlā me ka metala matrix. Ma hope o ke kinai ?ana a me ka ?elemakule, hiki i ka ikaika o ka ami welded ke pi?i i 90% ~ 95% o kēlā o ka hao metala.

(5) 5 a06 kinikini.

?O ke kinikini 5A06 no ke ka?ina al-mg-mn. He plastic ia i ka mahana o ka lumi a me nā mahana ki?eki?e, a kūpa?a nui i ka pala i nā ?ano media, e like me ka wai kai. ?O ke kūpa?a kūpale maika?i a me ka hiki ke ho?opa?a ?ia o ke kinikini e ho?onui ākea. ho?ohana ?ia i ka ?oihana moku. ?O ka weld o ke kinikini he ikaika ki?eki?e a me ka waiwai lula. Ma ke ana wela o ka lumi, hiki i ka ikaika o ka ami welded ke pi?i i 90% ~ 95% o kēlā me ka metric matrix.

?O ka mea i luna ka ho?olaha o kekahi o nā alloys alumini extruded extruded a me ko lākou ?ano. He a mākou nā hui extrusion alumini ma?amau, hiki ke hā?awi: extrusion alumini extrusion, extrusion alumini extrusion a me nā lawelawe ?ana i hana pilikino ?ia, ?olu?olu e nīnau
