The Ultimate Encyclopedia of 1050 Iphepha leAluminiyam (I-Aluminiyam enyulu yoRhwebo): Uhlalutyo olunzulu ukusuka kwiMetallurgy ukuya kwiSicelo esiSebenzayo
I. Isishwankathelo kunye nokuma kweMathiriyeli
1050 Iphepha leAluminiyamyeka 1xxx uthotho ialloys aluminiyam. Ngokweengqungquthela zamagama zamazwe ngamazwe, imele i-aluminiyam ecocekileyo yorhwebo kunye nomxholo we-aluminiyam ongekho ngaphantsi 99.5%. Ngokuqhelekileyo ibizwa ngokuba 1050kuMgangatho weSizwe waseTshayina (Gb / t), ngelixa kwimigangatho yaseYurophu (Ngaphakathi), idla ngokubizwa ngokuba AW-1050A (EN AW-Al99.5)ngokuchazwa kwamanani 3.0255. Kwakhona libakala elibhalisiweyo eliqhelekileyo kwi-Aluminium Association (Aa) imigangatho.
Njenge I-nof-share-inyanga, ixabiso elingundoqo le 1050 ayilali kumandla ayo okusebenza, kodwa endaweni yayo ukuzinza okukhulu kweekhemikhalikwaye iimpawu zomzimba (conductivity yombane, conductivity thermal, kunye nokubonakalisa). Idlala indima a “imathiriyeli yesiseko” ngaphakathi kwintsapho yealluminiyam, ifana nentsimbi ethambileyo (I-E.G., Q235) kushishino lwentsimbi. Inkqubo yayo yokuvelisa evuthiweyo kunye neendleko eziphantsi zokuphosa / ukuqengqeleka zenza ukuba ibe yinto esisiseko sokudibanisa, ukuqhuba, i-anti-corrosion, kunye nezicelo zesitampu ezinzulu.
🔍 Utoliko olunzulu:
- Kutheni ukhetha 1050 ngaphaya 1060?Ngexesha 1060 inobunyulu obuphezulu (99.6%), 1050 inikeza ulungelelwaniso olungcono phakathi kwamandla kunye nokwakheka, kwaye idla ngokukhuphisana ngeendleko.
- Ingaba yin “enganyangekiyo ngobushushu” thetha?Kuthetha ukuba awukwazi ukonyusa ubulukhuni bayo ngokucinywa kunye nokuguga njengoko ubuya kwenza nge-6061-T6.. Amandla ayo anokwandiswa kuphela ukusebenza okubandayo (qengqeleka, umzobo).
II. Iimpawu zeMetallurgical kunye neMicro-Mechanisms
1. Ubume beCrystal kunye neDuctility
1050 ialuminiyam ine-a ICubic egxile kubuso (I-FCC)isakhiwo sekristale. Esi sakhiwo sinika imathiriyeli ukuqina okuphezulu kakhulu kunye ne-ductility, kwaye ayithandeki kwiinguqu ezinqabileyo nakwimimandla yobushushu obuphantsi (njengamaqondo obushushu enitrogen), ngokungafaniyo nezinye iintsimbi eziphethwe bubuqhophololo obubandayo. Kungenxa yoko le nto 1050 ifanelekile kakhulu kwi-linings kwizixhobo ze-cryogenic (I-E.G., abathwali be-LNG).
2. Umboniso bhanyabhanya we-oksidi wokuziphilisa
Ialuminiyam esulungekileyo ikhawuleza idibane neoksijini esemoyeni yenze umaleko oshinyeneyo γ-Al₂O₃ (icorundum) ifilimumalunga 2-10 I-Nanometers inzima. Le filimu idibene ngokugqithisileyo kwaye ikhusela i-oxidation eyongezelelweyo yentsimbi yangaphakathi. Ukuba umphezulu ukrwele, ifilim entsha yeoksidi yenza ngoko nangoko ekuvezweni emoyeni okanye emanzini. Esi sesona sizathu sisisiseko sokumelana kwayo nokugqwesa okuphezulu kakhulu xa kuthelekiswa nentsimbi yekhabhoni eqhelekileyo.
III. Ukubunjwa kweMichiza eneenkcukacha (Ipesenti yeMisa %)
Ukubunjwa kweekhemikhali ezichanekileyo ngundoqo ekunqumeni ukusebenza kwe 1050. Nokuba ukulandelela ukungcola kunokuchaphazela kakhulu ukuhanjiswa kunye nokusebenza kokusebenza.

Q&A
Q1: Ngaba 1050 Iphepha le-aluminiyam lisetyenziselwe iidekhi zeenqanawa okanye iinxalenye zesakhiwo kwindawo yasemanzini olwandle?
A: Ayikhuthazwa kwaphela.Nangona 1050 imelana nokuhlwa kwe-atmospheric, inobuntununtunu kakhulu iiyoni zekloridi (Cl⁻). Amanzi olwandle atyebile kwiikloridi, nto leyo enokubangela umhlwa wemingxuma kunye nomhlwa kwimingxuma, ukungena ngokukhawuleza amaphepha amancinci. Iimeko zaselwandle kufuneka zisebenzise uthotho lwe-5xxx (I-E.G., 5052, 5083) ialloys Al-Mg, ezikwaziyo ukumelana namanzi olwandle.
Q2: Kutheni i-H14 inomsindo 1050 Iphepha le-aluminium liqhekeka ngokulula ngexesha lokugoba?
A:Kusenokubakho izizathu ezithathu:
- Goba iRadiyo iNcinci kakhulu: Nangona i-H14 inesiqingatha-nzima, isafuna ukulandela ubuncinci beradiyasi yokugoba (ngokuqhelekileyo kucetyiswa 1.0t ~ 1.5t, apho t bubunzima bepleyiti); incinci kakhulu i-engile engu-R iya kubangela ukukrazuka kwecala elingaphandle.
- Ukwalathiswa kweenkozo (Anisotropy): Amaphepha e-aluminiyam anesikhokelo sokuhamba kwefiber ngexesha lokuqengqeleka. I-Bendability ingcono ukuba umgca wokugoba u-perpendicular ukuya kwi-rolling direction; kunokwenzeka ukuba iqhekeke ukuba ihambelana nendlela yokuqengqeleka.
- Ukungcola Kwezinto Ezibonakalayo: Ukuba ukungcola kwentsimbi kunye ne-silicon kukumda ophezulu, okanye ukuba ubungakanani bengqolowa burhabaxa, iplastiki nayo iya kuncipha.
Q3: Ngaba 1050 I-Anodizing inzima?
A: Kunzima kwaye akukhuthazwa.I-anodizing enzima ihlala ifuna ubukho bezinto ezifana ne-magnesium kunye ne-silicon (I-E.G., 6061) ukuxhasa ubulukhuni kunye nokunamathela kwefilimu eshinyeneyo ye-oxide. Ifilimu ye-oxide eyenziwa yi-aluminiyam ecocekileyo 1050 ithambile kwaye inzima ukwenza ifilimu eshinyeneyo (ngokuqhelekileyo <25μm), kunye nokuqina kwayo kunye nokumelana nokunxiba kukude nokuhlangabezana nemigangatho ye-anodizing enzima.
Q4: Kutheni kunjalo 1050 Iphepha le-aluminiyam ngamanye amaxesha lijika libe mnyama okanye liphuhlise amabala amhlophe emva kokugcinwa ixesha elithile?
A:Ngokuqhelekileyo oku kubangelwa ukupakishwa kakubi.
- Amabala amhlophe: Ngokuqhelekileyo amabala amanzi okanye iintsalela zealkaline. Ubumanzi obuvaleleke phakathi kwamashiti abunakujika bube ngumphunga, ebangela umhlwa wendawo.
- Ubumnyama: Okusenokwenzeka i-oyile oxidation okanye ukudibana nerabha / iiplastiki ezikhupha isulfide. Ngalo lonke ixesha sebenzisa izinto zokupakisha ezingathathi hlangothi kwaye uqinisekise ukuba indawo yokugcina yomile kwaye ingena umoya.
Q5: Ngaba kukho umahluko omkhulu wexabiso phakathi 1050 kwaye 1060? Apho yahluke kakhulu?
A:Umahluko wamaxabiso ngetoni nganye udla ngokuba ngamakhulu ambalwa e-RMB. Umahluko ikakhulu ulele:
- Iindleko zeMpathi ekrwada: 1060 ifuna ukucoceka okuphezulu kwee-ingots ze-aluminiyam, kwaye iimfuno zokuphinda zisetyenziswe kwizinto ezilahliweyo zingqongqo.
- Ulawulo Lwenkqubo: Ukuvelisa 99.6% ucoceko aluminiyam sheet kufuna iinkqubo ezicolekileyo zokulawula ukungcola kunokuba 99.5%.
- Umahluko weSicelo: Ukuba imfuno ye-conductivity ayibalulekanga kakhulu (I-E.G., iitsinki zobushushu eziqhelekileyo vs. iibhasi zebhasi zombane ophezulu), 1050 inikeza ukusebenza kakuhle kweendleko.
Q6: Ndimele ndenze ntoni ukuba amandla ka 1050 Iphepha le-aluminium liyancipha emva kwe-welding?
A:Le yinto eqhelekileyo (isiphumo sokuthomalalisa). Ubushushu be-arc bubangela ukuba kuphele ukusebenza okubandayo kwi-weld kunye nendawo echatshazelwe bubushushu, ukubuyela kwimo ethambileyo kufutshane ne-O temper. Ukuba isakhiwo sifuna amandla, i Ubunzima obunqamlezayo kwi-weld kufuneka bunyuswengexesha loyilo lokubuyisela ukulahleka kwamandla, okanye ucinge ngokusebenzisa iindlela zoqhagamshelwano ngoomatshini ezifana ne-riveting okanye i-adhesive bonding endaweni yewelding.
Isishwankathelo
1050 Iphepha leAluminiyamingaphezulu nje kwentsimbi; sisisombululo esiphantsi kweendleko ukuqhuba, ukutshatyalaliswa kobushushu, kunye ne-anti-corrosioniimfuno kwishishini langoku. Ibingelela amandla aphezulu ngokutshintshiselana nokunyamezela ukusetyenzwa okungenakulinganiswa kunye nokuzinza kweekhemikhali. Nokuba uyila isibane se-LED esifuna ukuchithwa kobushushu okusebenzayo, ukukhangela imathiriyeli yezikhongozeli zeekhemikhali ezixhathisa iasidi-alkali, okanye ifuna isitampu sezixhobo ezintsonkothileyo ngobuninzi, 1050 Iphepha leAluminiyamkukuthanda kwakho “ukubheja okukhuselekileyo” kwaye “ukhetho lwezoqoqosho.”
