Uninzi lweealloys zealuminium ezigqityiweyo kunye neempawu zazo

Zithini iimpawu zealloys zealuminium eziqhelekileyo? I-China aluminium extrusion mveliso ukuze ufunde okungakumbi:

(1) 1035 ingxubevange.

I-alloy ye-1035 yi-aluminium esulungekileyo yemizi-mveliso ene-inshurensi engaphantsi kwe-0.7%, phakathi kwayo isinyithi kunye nesilicon zezona zinto zingcolileyo.Iron kunye nesilicon kunye nokunye ukungcola kwesinyithi kungabuphucula kancinci amandla, kodwa kunciphise ubukhulu beplastikhi kunye nokuziphatha kwealloy.

Umzi mveliso we-aluminium emsulwa uzinzo oluphezulu lweekhemikhali kwimithombo yeendaba emininzi, ephezulu kunezinye izinto zesinyithi ezinamandla aphezulu.Ukuzinza okuphezulu kweekhemikhali kwealuminium kungenxa yokwenziwa kwefilimu ebhityileyo, eshinyeneyo ebusweni bealuminiyam.

Ukungcola okungaphantsi kwi-aluminium (ngakumbi i-iron kunye ne-silicon), ukuphakama kwayo kukumelana nokubola, kwaye i-magnesium kunye ne-manganese kuphela ayikunciphisi ukubola kwe-aluminium.

Iimveliso ezigqityiweyo ze-1035 alloy zibonelelwa phantsi kokuncitshiswa kunye nokutshiswa okutshisayo, nangona kunjalo, nokuba imeko yonikezelo, inkqubo yokugqibela yokuqhubekeka kweprofayili ekhutshiweyo kukuzolula, okunokulungiswa kumatshini wokulungisa. ipropathi yamandla iphuculwe kancinci, kodwa iplastiki iyancipha ngokuqatha.

Ukongeza, ukuqhuba kombane kwe-alloy kuphuculwe kancinci ngexesha lokubanda. Ngenxa yoko, xa iimfuno zephrofayili zisebenza ngokungqongqo, kufuneka uqwalasele utshintsho lomsebenzi olungentla xa ulungelelanisa.

Xa ubushushu bonyuswe, amandla kunye neplastiki ye-1035 alloy inyuke kakhulu.Xa iqondo lobushushu lingaphantsi kwe-zero, amandla kunye neeplastikhi zepropathi ye-alloy ziphuculwe kakhulu.

(2) 3 a21 ingxubevange.

I-alloy 3A21 yintsimbi ekhubazekileyo kwinkqubo ye-AlMn yokubambela ine-corrosion ephezulu kwaye iyafana naleyo ye-1035 alloy. Iimveliso ezigqityiweyo ze-3A21 alloy zikulungele kakuhle ukuwelda ngegesi, i-hydrogen welding, i-argon arc welding kunye Ukuxhathisa i-welding, ukumelana ne-weld kuyafana nesiseko sesinyithi.I-alloy inesenzo esihle sokumiliselwa kwiindawo ezibandayo nezishushu, kwaye uluhlu lobushushu lwe-deformation ye-thermal lubanzi kakhulu (320 ~ 470C). Ukomelezwa ngonyango lobushushu kwaye iiprofayili ze-alloy zibonelelwa zikwimeko eyojiweyo okanye ekhutshiweyo.

Iziphumo zobushushu be-deformation kunye nesantya se-deformation ekumelaneni ne-deformation ye-3A21 alloy ingaphantsi kakhulu kune-aluminium emsulwa yemizi-mveliso.

(3) 6063 ingxubevange.

Njengommeli oqhelekileyo we-a1-mg-si alloy, i-alloy 6063 ine-extrudability egqwesileyo kunye ne-weldability, kwaye yeyona nto ikhethiweyo yokwakha iWindows kunye neengcango.Ibonakaliswa ngeplastikhi ephezulu kunye nokumelana nomhlwa phantsi kwemeko yeqondo lobushushu kunye nesantya soxinzelelo Akukho uxinzelelo umhlwa tendency.Ngexesha welding, nokumelana akuthethi ukwehla.

I-Alloy 6063 yomelezwa ngokuqinileyo ngexesha lokunyanga kobushushu. Amanqanaba aphambili okomeleza kwi-alloy yiMgSi kunye neAlSiFe. Ukucima kunye nokuguga kwendalo ngeli xesha, ukunyuka kwesihlobo kuncipha kancinci (ukusuka kwi-23% ~ 25% ukuya kwi-15% ~ 20%) .Emva kokuguga okungekhoyo kwi-160 ~ 170 ℃, ingxubevange inokufumana isiphumo esomeleleyo. Ngeli xesha, amandla okuqina anyuswe ukuya kuma-269.5 ~ 235.2MPa Nangona kunjalo, ekugugeni okwenziweyo, iiplastikhi zepropathi zehle kakhulu (= 10% ~ 12%).

Ixesha lokuphumla phakathi kokucinywa kunye nokuguga okungekuko kunefuthe elibonakalayo kwinqanaba lokuqinisa i-6063 alloy (ekwaluphaleni okungengokwamanyala). Ngokunyuka kwexesha lekhefu ukusuka kwi-15min ukuya kwi-4h, amandla eqine kunye namandla okuvelisa ancipha ukuya kwi-29.4 ~ 39.2MPa. Ixesha lokugquma nge-thermal ngexesha lokuguga okungekho mpembelelo kwiimpawu zomatshini ezingama-6063 zeemveliso ezigqityiweyo.

(4) 6 njani a02 ingxubevange.

I-alloy yesiqhelo ye-6A02 (ngaphandle kokuthintelwa komxholo wobhedu) ye-a1-mg-si-cu series alloy.Iineempawu eziphezulu kakhulu zeplastikhi kwimeko yeqondo lobushushu-velocity yoxinzelelo machining nakwiqondo lobushushu egumbini.

Kwimveliso ye-6A02 ye-alloy ekhutshwe iimveliso ezigqityiweyo, nangona umxholo wayo we-manganese umncinci, kodwa emva konyango lobushushu alunakugcina sakhiwo siphinde senziwa kwakhona, ke ngoko, sinokuphucula kakhulu ukusebenza kwamandla.Ngokufana ne-6063 alloy, i-6A02 ingxubevange ikhawuleza yomelele ngexesha lonyango lobushushu, kwaye izigaba zayo eziphambili zokomeleza ziiMg2Si kunye neW (AlxMg5Si4Cu).

Amandla okuqina angonyuswa ngokuguga kwendalo emva kokucinywa, okuphindwe kabini ukuphakama kokuphantsi kokubanjwa, kwaye ukuphinda kabini ukuphakama kokuguga okungekuko emva kokucinywa, nangona kunjalo, ekugugeni okwenziweyo, iplastikhi yepropathi yehle kakhulu. yehle malunga ne-1/2, kunye noxinzelelo olunxulumene nolwehle ngaphezulu kwe-2/3).

I-alloy ye-6A02 yahlukile kwi-6063 alloy. I-6063 alloy inokumelana nokubola okuphezulu kwimeko yokuguga yendalo kunye nokuguga okungekho mthethweni, ngelixa ukumelana nokubola kwe-6A02 kwehla ngokungacacanga kwaye ukuthambekela kwe-intercrystalline umhlwa kubonakala.

Kwinkqubo yokubola, njengoko umxholo wobhedu kwi-alloy unyuka, amandla okuphulukana namandla ayenyuka. Umzekelo, ukuba umxholo wobhedu uyi-0.26%, emva kweenyanga ezi-6 zovavanyo (ukutshiza ngesisombululo se-NaCl esingu-30%), amandla oqiniso lwengxubevange ancipha ngama-25%, ngelixa ubude bawo buncipha ngama-90%. ukuphucula ukumelana nokubola, umxholo wobhedu kwi-alloy uhlala ulawulwa ngaphantsi kwe-0.1%.

I-6A02 i-alloy ingafakwa nge-welding, i-roll welded kunye ne-argon arc i-welded. Amandla edibeneyo edibeneyo yi-60% ~ 70% yaloo matrix yensimbi. Emva kokucima kunye nokuguga, amandla omdibaniso odibeneyo unokufikelela kwi-90% ~ 95% yaloo nto yesinyithi sematriki.

(5) 5 a06 ingxubevange.

I-alloy 5A06 yeyothotho lwe-al-mg-mn. Yiplastikhi kakhulu kwiqondo lobushushu kwigumbi nakumaqondo obushushu aphezulu, kwaye iyamelana kakhulu nokubola kwimithombo eyahlukeneyo yemithombo yeendaba, kubandakanya namanzi olwandle. I-welding ye-alloy inamandla amakhulu kunye nepropati yeplastiki. Kwiqondo lokushisa kwegumbi, amandla omdibaniso odibeneyo unokufikelela kwi-90% ~ 95% yensimbi ye-matrix.

Oku kungasentla kukwaziswa kweendlela eziqhelekileyo zealuminium aluminium kunye neempawu zazo iinkampani ze-aluminium zesiko, Unokubonelela: isikwere ialuminium extrusion, ukujikeleza ialuminium extrusion kunye nezinye iinkonzo zokwenza ngokwezifiso, wamkelekile ukudibana
