Monga ma aluminiyamu awiri omwe amagwiritsidwa ntchito kwambiri m'mafakitale, 5052 ndi 6061 amaphimba zochitika zosiyanasiyana, kuchokera kumlengalenga kupita kumalo ogwiritsira ntchito anthu, kutengera mapangidwe awo apadera komanso ubwino wa ntchito. M'nkhaniyi, tiwona kusiyana kwakukulu, mawonekedwe a kagwiridwe ka ntchito ndi zochitika za kagwiritsidwe ntchito ka mitundu iwiriyi yazitsulo zotayidwa kuti zipereke chidziwitso cha akatswiri kuti asankhe molondola.

Kodi 5052 Aluminium Alloy ndi chiyani?

5052 zotayidwa aloyi ndi 5xxx aloyi zotayidwa-magnesium aloyi, pachimake alloying chinthu ndi magnesium (zokhutira 2.2% -2.8%), amene ndi mmene sanali kutentha mankhwala kulimbikitsa aloyi.
Ndi aloyi wamba wosatenthedwa wosatenthedwa. Sizingalimbitsidwe ndi kuzimitsa, kukalamba ndi njira zina zochizira kutentha, koma zimangodalira kuumitsa kuzizira kuti akwaniritse kuwonjezeka pang'ono kwa mphamvu, ndipo mapangidwe ake opanda mkuwa amapewa chiopsezo cha intergranular corrosion pa gwero lake. Makhalidwe ake apamwamba kwambiri okana kuwononga dzimbiri, omwe amawotchera kwambiri, kuumba komanso kutopa, ndizomwe zimayendera panyanja, mankhwala ndi zina zowononga kwambiri.
Chikhalidwe chodziwika bwino chogwirira ntchito ndi H32, H34, pomwe boma la H32 limaganizira za mphamvu ndi mawonekedwe ake, ndipo ndilodziwika kwambiri pakupanga mafakitale. Amagwiritsidwa ntchito kwambiri pokonza zochitika monga chitsulo chachitsulo ndi zigawo zowotcherera, ndipo ndizofunikira makamaka pazigawo zopepuka zomwe zimafuna kupindika ndi kuwotcherera mobwerezabwereza.

Kodi 6061 Aluminium Alloy ndi chiyani?

6061 zotayidwa aloyi wa 6xxx mndandanda wa zitsulo zotayidwa-magnesium-silicon zitsulo zotayidwa, pachimake aloyi zinthu zomwe ndi magnesium (0.8% -1.2%) ndi pakachitsulo (0.4% -0.8%), ndipo ndi tingachipeze powerenga kutentha mankhwala kulimbikitsa aloyi.
Kudzera T4, T6 ndi ena tempering ndondomeko akhoza kuzindikira kuwonjezeka kwambiri mphamvu, T6 boma ndi apamwamba mphamvu boma, pambuyo kuwotcherera akhoza kudzera yachiwiri kutentha mankhwala kubwezeretsa mphamvu, ndondomeko kusinthasintha ndi wamphamvu. Monga a“chilengedwe chonse”ya mbiri ya aluminiyamu yamafakitale, ili ndi chiyerekezo champhamvu ndi kulemera, makina osinthika komanso kukana kwa dzimbiri, ndipo ndiyoyenera kuchita zinthu zambiri komanso zofunikira pakukonza magawo osiyanasiyana.
Wamba wamba processing boma ndi T4 ndi T6, T4 boma ndi oyenera kupinda, kukhomerera kwambiri ndi njira zina kupanga, ndipo T6 boma ndi oyenera katundu katundu structural mbali, amene ndi mfundo yaikulu kwa ndege, magalimoto, zomangamanga, mwatsatanetsatane kupanga ndi madera ena, komanso mmodzi wa structural zitsulo zotayidwa kagawo kakang'ono ndi ntchito buku lalikulu kwambiri padziko lonse lapansi kupanga ndi kupanga.

5052 vs 6061: Magwiridwe Ofunika & Kufananitsa Kwabwino

5052 ndi 6061 ndi mitundu iwiri yogwiritsidwa ntchito kwambiri ya mbiri ya aluminiyamu yamafakitale, yomwe ili ndi kusiyana kwakukulu pamachitidwe ndi zabwino zake chifukwa cha mapangidwe osiyanasiyana komanso njira zolimbikitsira.

Key Performance Kuyerekezera

Chemical Composition

Zomwe zimapangidwira zimapanga maziko a alloy's magwiridwe ake ndipo imatsimikizira mwachindunji zabwino zake zazikulu komanso zoperewera zake:
Aluminium alloy 5052: Aluminiyamu-magnesium alloy yomwe ili ndi zotsalira za chromium komanso zonyansa zotsika kwambiri monga silicon, mkuwa, ndi chitsulo. Chifukwa chokhala ndi mkuwa wochepa, kukana kwake kwa dzimbiri ndikopambana kwambiri ndi zotayidwa wamba za aluminiyamu, ndipo zimasunga bata m'malo okhala ndi ma chloride ayoni, komanso m'malo acidic ndi amchere. Chromium imayeretsanso kukula kwa mbewu ndikuwongolera mawonekedwe amtundu.
Aluminium alloy 6061: Aluminiyamu-magnesium-silicon alloy yomwe ili ndi kuchuluka kwa mkuwa ndi chromium. The Mg₂Si gawo lopangidwa ndi kuphatikiza kwa magnesium ndi silicon ndikofunikira pakuwonjezera mphamvu panthawi yamankhwala otentha. Mkuwa umathandizira kulimba kwa maziko koma umachepetsa kukana kwa dzimbiri pang'ono, ndipo chromium imayenga kukula kwambewu kuti zitsimikizire kukhazikika kwa aloyi.'s makina katundu m'madera otentha kwambiri.

Mechanical Properties

Mukamagwiritsa ntchito makina opangira makina 5052-H32 ndi 6061-T6 ngati choyimira, kusiyana kwamakina kumatsimikizira kuyenerera kwa ntchitoyo:
Mphamvu yamphamvu / zokolola mphamvu: 6061-T6 (mphamvu yamphamvu 310 MPa / zokolola mphamvu 276 MPa) ndizokwera kwambiri kuposa zomwe 5052-H32 (mphamvu yamatenda 215)-265 MPa / zokolola mphamvu 160 MPa), imapereka mphamvu yabwino yonyamula katundu ndi kukana mapindikidwe, ndipo ndi yoyenera kwa ntchito zolemetsa kwambiri.
Kutopa kwamphamvu: Mphamvu ya kutopa ya 5052-H32 ndi 117 MPa, yomwe ili pafupifupi kawiri kuposa ya 6061-T6 (62 MPa), ndipo imagonjetsedwa ndi katundu wosiyanasiyana, kupanikizika mobwerezabwereza, ndi kugwedezeka, motero kukulitsa mankhwala.'s moyo wautumiki.
Ductility ndi kuuma: 5052 imasonyeza kutalika kwapamwamba komanso chiopsezo chochepa cha ming'alu ya mawonekedwe, ndikupangitsa kuti ikhale yoyenera kupanga zitsulo zovuta; Brinell kuuma kwa 6061 pafupifupi 95 (5052: 60), amene amapereka bwino kuvala kukana ndi extrusion kukana, kuzipanga kukhala oyenera mwatsatanetsatane mbali makina.

Kukaniza kwa Corrosion

Aluminiyamu aloyi 5052: Muyezo wamakampani pakukana kwa dzimbiri, wodziwika ngati a“kalasi yam'madzi”aluminiyamu aloyi, kugonjetsedwa ndi madzi a m'nyanja, ayoni kloride, zidulo ofooka, ndi dzimbiri zamchere; zimangowonetsa dzimbiri zazing'ono pakuyesa kupopera mchere kwa maola 500, palibe chiwopsezo cha kupsinjika kwa dzimbiri, palibe mankhwala owonjezera ofunikira, omwe angagwiritsidwe ntchito kwa nthawi yayitali m'malo ovuta komanso owononga.
6061 aluminium alloy: kukana bwino kwa dzimbiri m'malo wamba, magwiridwe antchito okhazikika pamafakitale owuma amkati; komabe, dzimbiri lalikulu la pitting limapezeka panthawi ya kuyesa kwa mchere wa maola 200 pansi pazikhalidwe zowononga kwambiri; Zomangamanga zomwe zimakhala ndi mkuwa zimakhala ndi dzimbiri la intergranular, ndipo anodic oxidation, kupopera mbewu mankhwalawa, ndi mankhwala ena apamtunda amafunikira kuti apititse patsogolo chitetezo.
