Ama-alloys amaningi ejwayelekile we-aluminium akhishwe nezici zawo

Yiziphi izici zezinhlamvu eziningana ezijwayelekile ezikhishwe nge-aluminium? I-china aluminium extrusion ifektri ukuze ufunde kabanzi:

(1) 1035 ingxubevange.

I-1035 alloy i-aluminium ehlanzekile yezimboni enokungcola okungaphansi kuka-0.7%, phakathi kwayo i-iron ne-silicon okungukungcola okuyinhloko I-ayoni ne-silicon nokunye ukungcola kwensimbi kungathuthukisa amandla kancane, kepha kunciphise kakhulu i-plasticity kanye ne-conductivity ye-alloy.

I-aluminium ehlanzekile yezimboni inokuqina okuphezulu kwamakhemikhali emithonjeni eminingi yezindaba, ephakeme kunezinye izinsimbi ezinamandla amakhulu.Ukuzinza okuphezulu kwamakhemikhali kwe-aluminium kungenxa yokwakhiwa kwefilimu elincane, eliminyene le-oxide ebusweni be-aluminium.

Ukungcola okuncane ku-aluminium (ikakhulukazi i-iron ne-silicon), kuphakamisa ukumelana nokugqwala kwayo.Ngokweqiniso, i-magnesium ne-manganese kuphela enganciphisi ukumelana nokugqwala kwe-aluminium.

Imikhiqizo eqeda ukwenziwa ye-1035 alloy inikezwa ngaphansi kokuncishiswa nokushiswa kwe-extrusion. Noma kunjalo, ngaphandle kwesimo sokuphakelwa, inqubo yokugcina yokulungiswa kwephrofayili ekhishiwe ingukuqondisa okulula, okungaqondiswa emshinini wokuqondisa roll. impahla yamandla ithuthukiswa kancane, kepha ipulasitiki incipha kakhulu.

Ngaphezu kwalokho, ukuqhutshwa kwamandla kagesi kwe-alloy kuthuthukiswa kancane ngesikhathi sokubanda okubandayo. Ngakho-ke, lapho izidingo zokusebenza kwephrofayili ziqinile, kuyadingeka ukuthi ucabangele izinguquko zokusebenza ezingenhla lapho uqondiswa.

Lapho izinga lokushisa lenyuswa, amandla kanye neplastiki ka-1035 alloy akhule kakhulu.Lapho izinga lokushisa lingaphansi kuka-zero, amandla nezakhiwo zepulasitiki ze-alloy zithuthukiswa kakhulu.

(2) 3 a21 ingxubevange.

I-alloy 3A21 ingxubevange ekhubazekile ku-AlMn kanambambili system.Ine-high corrosion resistance futhi icishe ifane naleyo ye-1035 alloy.Imikhiqizo eqediwe eqediwe ye-3A21 alloy ikufanelekele kahle ukushisela igesi, i-hydrogen welding, i-argon arc welding kanye contact welding.The ukumelana nokugqwala kwe-weld kuyefana nalokho kwesisekelo sensimbi.I-alloy inokusebenza okuhle kwe-deformation ezindaweni ezibandayo nezishisayo, futhi ibanga lokushisa lokushiswa kwe-thermal libanzi kakhulu (320 ~ 470C). qiniswa ukwelashwa kokushisa futhi amaphrofayli we-alloy ahlinzekwa esimweni esithunyelwe noma esikhishwe.

Umphumela wokushisa kwe-deformation kanye nesivinini se-deformation ekumelaneni ne-deformation ye-3A21 alloy kuncane kakhulu kune-aluminium ehlanzekile yezimboni.

(3) 6063 ingxubevange.

Njengommeleli ojwayelekile we-a1-mg-si alloy, i-alloy 6063 ine-extrudability enhle kakhulu futhi i-weldability, futhi iyinto ekhethwayo yokwakha iWindows nezicabha. Kubonakala ngopulasitiki ophakeme nokumelana nokugqwala ngaphansi kwesimo sokushisa nesivinini sokucindezela imishini .No ukucindezeleka ukugqwala tendency.During Welding, ukumelana ukugqwala akusho empeleni kwehle.

I-Alloy 6063 iqiniswa kakhulu ngesikhathi sokwelashwa kokushisa.Izigaba eziyinhloko zokuqinisa ku-alloy yiMgSi ne-AlSiFe.Uma amandla we-tensile wamaphrofayili we-6063 alloy extruded angama-98 ~ 117.6mpa esimweni sokuhlanganisa, amandla we-tensile angakhuphukela ku-176.4 ~ 196MPa ngemuva ukucima nokuguga kwemvelo.Ngalesi sikhathi, ukunwebeka okuhlobene kuncipha kancane (kusuka ku-23% ~ 25% kuye ku-15% ~ 20%) .Emva kokuguga okufakelwayo ku-160 ~ 170 the, i-alloy ingathola amandla amakhulu okuqinisa. Ngalesi sikhathi, amandla okuqina akhuphukele ku-269.5 ~ 235.2MPa. Nokho, ekugugeni okufakelwayo, izakhiwo zepulasitiki zehle kakhulu (= 10% ~ 12%).

Isikhathi sokuhlukanisa phakathi kokucima nokuguga okufakelwayo sinomthelela omkhulu ezingeni eliqinisayo le-6063 alloy (ekugugeni okufakelwayo). Ngokwanda kwesikhathi sokuphumula kusuka ku-15min kuye ku-4h, amandla we-tensile namandla we-isivuno ancipha afinyelela ku-29.4 ~ 39.2MPa.Isikhathi sokushisa esishisayo ngesikhathi sokuguga okungekho emthethweni sinomthelela omkhulu kuzakhiwo zemishini yemikhiqizo eqediwe engama-6063 alloy.

(4) 6 i-alloy engu-a02 kanjani.

Ingxubevange ye-6A02 ejwayelekile (ngaphandle komkhawulo wokuqukethwe kwethusi) ingeye-a1-mg-si-cu series alloy.Inezici zepulasitiki eziphakeme kakhulu ezimweni zokushisa-velocity zokucindezela imishini nasekamelweni lokushisa.

Ekukhiqizeni imikhiqizo engu-6A02 ye-alloy extruded semi-kumaliza, yize okuqukethwe kwayo kwe-manganese kuncane, kepha ngemuva kokwelashwa kokushisa akukwazi ukugcina isakhiwo esenziwe kabusha, ngakho-ke, singathuthukisa ukusebenza kwamandla kakhulu. Njenge-alloy 6063, ingxubevange engu-6A02 iyashesha iqiniswe ngesikhathi sokwelashwa kokushisa, futhi izigaba zayo ezinkulu zokuqinisa yiMg2Si ne-W (AlxMg5Si4Cu).

Amandla aqine angakhuphuka ngokuguga kwemvelo ngemuva kokucinywa, okuphindwe kabili kunalokho okungaphansi kokuncishwa, futhi cishe kuphindwe kabili kunalokho okungaphansi kokuguga okwenziwe ngemuva kokucishwa.Kodwa, ekuguqulweni okufakelwayo, impahla yepulasitiki yehle kakhulu (ukunwebeka okuhlobene kwehle cishe ngo-1/2, futhi ukucindezelwa okuhlobene kwehle ngaphezu kuka-2/3).

Ingxubevange engu-6A02 yehlukile kwengxube engu-6063. Ingxubevange engu-6063 inokumelana okuphezulu kokugqwala kokubili esimweni semvelo sokuguga nesimo sokuguga okufakelwayo, kuyilapho ukumelana nokugqwala kwe-6A02 alloy kuncipha ngokusobala futhi ukuthambekela kwe-intercrystalline ukugqwala kuvela. Ukuphakama kokuqukethwe kwethusi ku-6A02 alloy, lapho ukumelana nokugqwala kuyehla.

Ngenqubo yokugqwala, njengoba okuqukethwe ithusi ku-alloy kukhuphuka, amandla okulahleka kwamandla nawo ayanda. Isibonelo, uma okuqukethwe ithusi kungu-0.26%, ngemuva kwezinyanga eziyi-6 zokuhlolwa (kufafazwa isisombululo se-NaCl esingu-30%), amandla aqine we-alloy ancipha ngo-25%, kuyilapho ubude bawo bungancipha ngo-90% .Ngakho-ke, ukuze thuthukisa ukumelana nokugqwala, okuqukethwe ithusi ku-alloy kuvame ukulawulwa ngaphansi kuka-0.1%.

I-6A02 ingxube ingafakwa i-welded, i-roll i-welded ne-argon arc i-welded. Amandla we-welded joint angama-60% ~ 70% alowo we-matrix metal.After ukucima nokuguga, amandla we-welded joint angafinyelela ku-90% ~ 95% yalokho yensimbi ye-matrix.

(5) 5 a06 ingxubevange.

I-alloy 5A06 ingeyochungechunge lwe-al-mg-mn. Iyipulasitiki kakhulu ekamelweni lokushisa nasemazingeni okushisa aphezulu, futhi imelana kakhulu nokugqwala emithonjeni eyahlukahlukene yezindaba, kufaka phakathi amanzi olwandle. Ukumelana okuhle nokugqwala kwe-alloy kukwenza kube banzi esetshenziswa embonini yokwakha umkhumbi.I-weld ye-alloy inamandla amakhulu kanye nempahla yepulasitiki.Ethempeleni lokushisa, amandla okuhlangana ashiselwe angafinyelela ku-90% ~ 95% yalokho kwensimbi ye-matrix.

Lokhu okungenhla ukwethulwe kwama-alloys e-aluminium akhonjiwe amaningi kanye nezici zawo izinkampani ezenziwe ngokwezifiso ze-aluminium extrusion, ingahlinzeka: isikwele se-aluminium extrusion, nxazonke ze-aluminium extrusion nezinye izinsizakalo zokuphrinta ezenziwe ngezifiso, wamukelekile ukubonisana
