Yawancin nau'ikan ginshiƙan aluminum da aka haɓaka da halayensu

Menene halaye na nau'ikan ginshiƙan aluminum da aka fitar da su? China aluminum extrusion ma'aikata don ƙarin koyo:

(1) 1035 gami

1035 alloy shine allo mai tsabta na masana'antu tare da kasa da 0.7% ƙazanta, daga cikinsu ƙarfe da siliki sune manyan ƙazanta.Iron da silicon da wasu ƙazamtattun ƙarfe na iya ɗan inganta ƙarfin, amma yana rage haɓakar filastik da haɓakar gami.

Tsarkakakken Aluminium na masana'antu yana da kwanciyar hankali mai ƙarfi a cikin kafofin watsa labarai da yawa, wanda ya fi sauran ƙarfe masu ƙarfi. .The Haƙƙarfan zaman lafiyar sinadarai na aluminum yana faruwa ne saboda samuwar fim mai ƙarancin nauyi, mai yawa a saman aluminum.

Impananan ƙazantar da ke cikin aluminum (musamman ƙarfe da siliki), mafi girman haɓakar lalatawarta.A zahiri, magnesium da manganese ne kawai ba su rage juriya ta lalata aluminiya.

Ana samarda samfuran da aka gama dasu na 1035 gami a ƙarƙashin haɗawa da zafi mai zafi.Kodayake, ba tare da la'akari da yanayin wadatarwa ba, aikin aiwatarwa na ƙarshe na bayanan martaba shine madaidaiciya madaidaiciya, wanda za'a iya daidaita shi akan injin madaidaitan mirgine. Lokacin daidaitawa, propertyarfin ƙarfin an inganta shi kaɗan, amma filastik yana raguwa sosai.

Bugu da ƙari, haɓakar wutar lantarki ta allo yana da ɗan inganta yayin ɓarna mai sanyi.Saboda haka, lokacin da bukatun aikin bayanan martaba suke da tsauri, ya zama dole a yi la’akari da canje-canjen aikin da ke sama lokacin daidaitawa.

Lokacin da zafin jiki ya karu, karfi da filastik na gami 1035 ya karu sosai.Lokacin da zafin jiki ya kasa sifili, karfi da kaddarorin filastik na gami suna da matukar inganta.

(2) 3 a21 gami

Alloy 3A21 wani gurbataccen gami ne a cikin tsarin AlMn binary.Yana da juriya na lalata mai yawa kuma kusan iri daya ne da na gami na 1035. Samfuran da aka gama dasu na 3A21 gami sun cancanci walda na gas, walda hydrogen, wallon arc arc da kuma hulda waldi.Wurin juriya na walda ya yi daidai da na asalin karfe. Gami yana da kyakkyawan nakasawa a cikin jihohin sanyi da zafi, kuma yanayin zafin jiki na nakasawar yanayi yana da fadi sosai (320 ~ 470C). za a ƙarfafa ta magani mai zafi kuma ana ba da bayanan bayanan gami a cikin yanayin ɓarna ko ɓarna.

Sakamakon zafin jiki mara kyau da saurin lalacewa akan juriya na nakasawa na gami da 3A21 yana da ƙasa da na masana'antar tsarkakakken aluminum.

(3) 6063 gami

A matsayina na wakilin a1-mg-si gami, gami da 6063 yana da kyakkyawar fitarwa da waldawa, kuma shine kayan da aka fi so don gina Windows da kofofi.Wannan yana dauke da filastik mai yawa da kuma juriya lalata a ƙarƙashin yanayin zafin jiki da saurin saurin inji .Babu damuwa da halin lalatawar.Da walda, juriya ta lalata ba ta raguwa da gaske.

Alloy 6063 yana da ƙarfi sosai yayin magani mai zafi.Matsalolin ƙarfafa ƙarfi a cikin gami sune MgSi da AlSiFe.Idan ƙarfin zafin jiki na 6063 alloy extruded bayanan martaba shine 98 ~ 117.6mpa a cikin jihar haɗuwa, ƙarfin ƙarfin zai iya ƙaruwa zuwa 176.4 ~ 196MPa bayan quenching da tsufa na halitta.A wannan lokacin, dangin elongation yana ragu kadan (daga 23% ~ 25% to 15% ~ 20%) .Bayan tsufa na wucin gadi a 160 ~ 170 ℃, gami na iya samun sakamako mai karfi. A wannan lokacin, ƙarfin ƙarfin ƙarfin ya ƙaru zuwa 269.5 ~ 235.2MPa.Haka dai, a cikin tsufa na wucin gadi, dukiyar filastik ta ragu sosai (= 10% ~ 12%).

Lokaci tsakanin tazarar da tsufa na wucin gadi yana da mahimmin tasiri akan ƙarfin ƙarfafan kayan haɗin 6063 (cikin tsufa na wucin gadi). Tare da haɓakar tazara daga 15min zuwa 4h, ƙarfin zafin jiki da ƙarfin samar da ƙarfi ya ragu zuwa 29.4 ~ 39.2MPa.Lokacin lokacin sanyayawar zafin jiki a lokacin tsufa na wucin gadi ba shi da wani tasiri a kan kayan aikin injina na 6063 gami da aka gama kayayyakin.

(4) 6 yaya a02 gami.

Gwanin 6A02 na yau da kullun (ba tare da iyakancewar abun jan ƙarfe ba) na a1-mg-si-cu jerin gami ne.Yana da kaddarorin filastik masu girma sosai a yanayin saurin-zafin jiki na aikin inji da zafin jiki a ɗakin.

A yayin samar da gami na 6A02 wanda aka fitar da kayayyakin da aka gama dasu, duk da cewa kayan manganese dinsu kadan ne, amma bayan maganin zafi ba zai iya kula da wani tsarin da aka sake sanya shi ba, saboda haka, zai iya inganta karfin aiki sosai.Kamar gami 6063, gami na 6A02 yana cikin sauri duringarfafa yayin maganin zafi, kuma manyan matakan ƙarfafawa shine Mg2Si da W (AlxMg5Si4Cu).

Thearfin zafin jiki na iya ƙaruwa ta tsufa na halitta bayan quenching, wanda ya ninka na wanda ke karkashin jini, kuma ya ninka na wanda ke ƙarƙashin tsufa na wucin gadi bayan hucewar. Amma duk da haka, a cikin tsufa na wucin gadi, dukiyar roba ta ragu sosai (dangin elongation) ya ragu da kusan 1/2, kuma dangin danniya ya ragu da fiye da 2/3).

Gwajin 6A02 ya bambanta da kayan haɗin 6063. 6063 gami yana da matukar tsarguwa a yanayin tsufa da yanayin tsufa na wucin gadi, yayin da juriyar lalata ta 6A02 gami ya ragu a bayyane kuma dabi'ar lalata ta bayyana. Mafi girman abun tagulla a cikin gami na 6A02, yayin da juriya ta lalata karfin yake raguwa.

A cikin aikin lalata, yayin da abun ƙarfe na ƙarfe a cikin gami yake ƙaruwa, ƙarfin hasara mai ƙarfi shima yana ƙaruwa. Misali, idan abun tagulla yakai kashi 0.26%, bayan watanni 6 na gwaji (fesawa da 30% NaCl solution), karfin zafin na alli yana raguwa da 25%, yayin da dangin sa tsawo yake raguwa da 90% .Saboda haka, domin inganta lalata juriya, abun jan ƙarfe a cikin gami yawanci ana sarrafa shi ƙasa da 0.1%.

6A02 gami na iya zama mai walda, birgima mai walda da argon arc welded.The ƙarfi na walda hadin gwiwa ne 60% ~ 70% na cewa na matrix karfe .Bayan quenching da tsufa, ƙarfin walda hadin gwiwa iya isa 90% ~ 95% na cewa na matrix karfe.

(5) 5 a06 gami.

Alloy 5A06 yana cikin jerin al-mg-mn.Yana da filastik sosai a yanayin zafin daki da kuma a yanayin zafi mai yawa, kuma yana da matukar juriya ga lalatawa ta hanyoyin watsa labarai da yawa, gami da ruwan teku. Kyakkyawan juriya da lalata walda na sanya shi yaduwa An yi amfani dashi a cikin masana'antar kera jirgi.Weld na gami yana da ƙarfi mai ƙarfi da kayan roba. A cikin zafin jiki na ɗaki, ƙarfin haɗin haɗin zai iya kaiwa 90% ~ 95% na ƙarfe na matrix.

Abinda ke sama shine gabatarwar kayan haɗin gwal na aluminium da yawa da halayen su.We ne a Kamfanoni masu haɓaka aluminum, na iya samar da: murabba'in aluminum extrusion, zagaye aluminum extrusion da sauran musamman aiki ayyuka, maraba da tuntubar
