Dzakati wandei dzakajairwa dzakabudiswa aluminium alloys uye yavo hunhu

Ndeapi maitiro eanoverengeka akajairwa extruded aluminium alloys? Tevedzera iyo China aluminium extrusion fekitori kudzidza zvakawanda:

(1) 1035 chiwanikwa.

1035 alloy indasitiri yakachena aruminiyamu ine isingasviki 0.7% marara, pakati payo simbi nesilicon ndiyo yakasviba zvakanyanya.Iron nesilicon uye nezvimwe zvisakachena zvesimbi zvinogona kugadzirisa zvishoma simba, asi zvakanyanya kudzora plastiki uye kuitisa kweiyo alloy.

Maindasitiri akachena aruminiyamu ane yakakwira makemikari kugadzikana mune mazhinji midhiya, ayo ari akakwirira kupfuura mamwe simbi ane hurefu kugona. Iyo yakakwira kemikari kugadzikana kwealuminium inokonzerwa nekuumbwa kwechitete, chakakora oxide firimu pamusoro pealuminium.

Izvo zvishoma zvakasviba mualuminium (kunyanya iron uye nesilicon), iyo inokwidza ngura yayo kuramba, Ichokwadi, chete magnesium uye manganese hazvideredze ngura kuramba kwealuminium.

Semi-apedza zvigadzirwa zve1035 alloy zvinopihwa pasi peannealing uye inopisa extrusion Zvisinei, zvisinei nemamiriro ezvinhu ekupa, yekupedzisira kugadzirisa maitiro eiyo extruded mbiri ndeyekutwasanudza kutwasuka, uko kunogona kutwasanurwa pamupumburu unosimudza muchina. iyo simba reimba inovandudzwa zvishoma, asi mapurasitiki anoderera zvakanyanya.

Uye zvakare, iwo magetsi emagetsi ealloy akagadziridzwa zvishoma panguva yechando deformation, saka, kana chimiro chekuita kwacho chiri chakasimba, zvinodikanwa kufunga pamusoro apa shanduko yekuita kana uchisimudza.

Kana tembiricha yakawedzerwa, simba uye kugadzirwa kwe1035 alloy kwakawedzera zvakanyanya.Kana iyo tembiricha iri pazasi zero, simba uye epurasitiki zvimiro zvealloy zvakavandudzwa zvakanyanya.

(2) 3 a21 chiwanikwa.

Chiwanikwa 3A21 chinhu chakaremara chiwanikwa muAlMn bhainari system.Iine yakanyanya ngura kuramba uye yakafanana neiyo ye1035 alloy.Imi semi-yakapera zvigadzirwa zve3A21 alloy inonyatsokwanisa kugadziridza gasi, hydrogen welding, argon arc welding uye kusangana nekuwelda. Iyo ngura kuramba kweiyo weld yakafanana neiyo yesimbi simbi. Iyo alloy ine yakanaka deformation mashandiro mune inotonhora uye inopisa nyika, uye tembiricha renji yeanopisa deformation yakakura kwazvo (320 ~ 470C). Iyo alloy haigone isimbiswe nekupisa kwekupisa uye iwo maalloy profiles anopihwa mune yakakwenenzverwa kana yakabviswa mamiriro.

Mhedzisiro yekushomeka kwekushomeka uye kumhanyisa deformation pane kushomeka kwekushomeka kwe3A21 alloy yakanyanya kushoma pane yeiyo maindasitiri akachena aruminiyamu.

(3) 6063 chiwanikwa.

Semumiriri wea1-mg-si alloy, alloy 6063 ine yakanakisa extrudability uye weldability, uye ndiyo yakasarudzika zvinhu zvekuvaka Windows nemikova.Iyo inoratidzirwa nehupamhi hwepurasitiki uye ngura kuramba pasi pemamiriro ekushisa uye kumhanya kwekumanikidza machining. Hapana kunetseka ngura tendency.Panguva nomoto, kuti ngura nemishonga haanyatsoita kuderera.

Alloy 6063 inosimbiswa kwazvo panguva yekurapwa kwekupisa.Matanho makuru ekusimbisa mune chiwanikwa ndiMgSi neAlSiFe.Kana iyo tensile simba re6063 alloy extruded profiles iri 98 ~ 117.6mpa mune annealing state, iyo tensile simba inogona kuwedzerwa kusvika 176.4 ~ 196MPa mushure kudzima uye kuchembera kukwegura.Panguva ino, kuwanda kwehukama kunodzikira zvishoma (kubva pa23% ~ 25% kusvika pa15% ~ 20%) .Mushure mekukwegura kwekugadzira pa160 ~ 170 ℃, iyo alloy inogona kuwana yakasimba kusimbisa mhedzisiro. Panguva ino, iyo tensile simba inowedzerwa kusvika 269.5 ~ 235.2MPa Zvisinei, mukusakara kwekugadzira, epurasitiki zvivakwa zvakadzikira zvakanyanya (= 10% ~ 12%).

Iyo nguva yepakati pakati pekupedza uye kukwegura kwekugadzira ine simba rakakosha padanho rekusimbisa re6063 alloy (mukukwegura kwekugadzira). Nekuwedzera kwenguva yenguva kubva 15min kusvika 4h, iyo tensile simba uye goho simba rinoderera kusvika 29.4 ~ 39.2MPa. Iyo yekupisa yekumisikidza nguva panguva yekugadzira kukwegura haina chakakosha mhedzisiro pamakanika ehupfumi e6063 alloy semi-apedza zvigadzirwa.

(4) 6 sei a02 chiwanikwa.

Yakajairwa 6A02 alloy (isina muganho wemhangura zvemukati) ndeya a1-mg-si-cu akateedzana chiwanikwa. Iyo ine yakakwira kwazvo epurasitiki zvivakwa patembiricha-velocity mamiriro ekumanikidza machining uye patembiricha tembiricha.

Mukugadzirwa kwe6A02 alloy extruded semi-apedza zvigadzirwa, kunyangwe ayo manganese zvirimo zviri zvidiki, asi mushure mekurapa kwekupisa haigone kuchengetedza chimiro chakadzokororwa, nekudaro, chinogona kuvandudza zvakanyanya kushanda kwesimba. Senge 6063 alloy, iyo 6A02 alloy inokurumidza yakasimbiswa panguva yekurapa kwekupisa, uye ayo makuru ekusimbisa zvikamu ndeMg2Si uye W (AlxMg5Si4Cu).

Iyo tensile simba inogona kuwedzerwa nekuzvarwa kukwegura mushure mekudzima, iyo yakapetwa kaviri yakakwira seiya iri pasi pekuvharwa, uye ingangoita zvakapetwa zvakapetwa senge iri pasi pekunyepedzera kukwegura mushure mekudzima Zvisinei, mukukwegura kwekunyepedzera, iyo epurasitiki midziyo yakaderera zvakanyanya (hama kureba yakaderera neinenge 1/2, uye kumanikidza kwakaderera kwakadarika neanopfuura 2/3).

Iyo 6A02 alloy yakasiyana ne6063 alloy. Iyo 6063 alloy ine yakakwira ngura kuramba mune zvese zvakasarudzika kukwegura mamiriro uye yekunyepedzera kukwegura mamiriro, nepo iyo ngura kuramba kwe6A02 alloy inoderera pachena uye intercrystalline ngura maitiro anooneka. Iyo yakakwira iyo yemhangura yezvinhu mu6A02 alloy, iyo inowedzera iyo corrosion kuramba inoderera.

Mukugadzirisa, sezvo huwandu hwemhangura mune chiwanikwa ichiwedzera, kusimba kwekurasikirwa kwesimba kunowedzerawo. Semuenzaniso, kana iyo yemhangura iri 0.26%, mushure memwedzi mitanhatu yekuyedzwa (ichimwaya ne30% NaCl mhinduro), iyo tensile simba reiyo alloy inoderera ne25%, nepo kukwirisa kwayo kuenderana kuchiderera ne90% Saka, kuti kunatsiridza kuramba ngura, zvemukati zvemhangura mune chiwanikwa zvinowanzo kudzorwa zvisingasviki 0.1%.

6A02 alloy inogona kuve nzvimbo yakasungwa, roll yakakomberedzwa uye argon arc yakasungwa. Simba rejoni rakasunganidzwa i60% ~ 70% yeiyo yematrice simbi. Mushure mekupedza uye kukwegura, simba rejoni rakasungwa rinogona kusvika 90% ~ 95% yeiyo yesimbi yematrice.

(5) 5 a06 chiwanikwa.

Alloy 5A06 ndeye al-mg-mn nhepfenyuro. Iyo yakanyanya epurasitiki pane tembiricha yemukati uye pane yakanyanya tembiricha, uye inonyatsorwisa kuora mune dzakasiyana nhepfenyuro, kusanganisira mvura yegungwa. Iyo yakanaka ngura kuramba uye weldability yeiyo alloy inoita kuti ive yakawanda Weld yeiyo alloy ine yakasimba simba uye epurasitiki property.At kamuri tembiricha, simba re welded joini inogona kusvika 90% ~ 95% yeiyo yematrice simbi.

Izvi zviri pamusoro ndiko kuiswa kweakawanda akajairwa extruded aluminium alloys uye maitiro avo tsika aluminium extrusion makambani, Inogona kupa: mativi aruminiyamu extrusion, kutenderera aruminiyamu extrusion uye mamwe akagadziriswa ekugadzirisa masevhisi, unogamuchirwa kubvunza
