Menene halaye na nau'ikan ginshi?an aluminum da aka fitar da su? China aluminum extrusion ma'aikata don ?arin koyo:

(1) 1035 gami

1035 alloy shine allo mai tsabta na masana'antu tare da kasa da 0.7% ?azanta, daga cikinsu ?arfe da siliki sune manyan ?azanta.Iron da silicon da wasu ?azamtattun ?arfe na iya ?an inganta ?arfin, amma yana rage ha?akar filastik da ha?akar gami.

Tsarkakakken Aluminium na masana'antu yana da kwanciyar hankali mai ?arfi a cikin kafofin watsa labarai da yawa, wanda ya fi sauran ?arfe masu ?arfi. .The Ha??arfan zaman lafiyar sinadarai na aluminum yana faruwa ne saboda samuwar fim mai ?arancin nauyi, mai yawa a saman aluminum.

Impananan ?azantar da ke cikin aluminum (musamman ?arfe da siliki), mafi girman ha?akar 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 ?ar?ashin ha?awa da zafi mai zafi.Kodayake, ba tare da la'akari da yanayin wadatarwa ba, aikin aiwatarwa na ?arshe na bayanan martaba shine madaidaiciya madaidaiciya, wanda za'a iya daidaita shi akan injin madaidaitan mirgine. Lokacin daidaitawa, propertyarfin ?arfin an inganta shi ka?an, amma filastik yana raguwa sosai.

Bugu da ?ari, ha?akar wutar lantarki ta allo yana da ?an inganta yayin ?arna 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 ?arfafa ta magani mai zafi kuma ana ba da bayanan bayanan gami a cikin yanayin ?arna ko ?arna.
