Njengokuba usazi.wethui-aluminium tile trim/ i-aluminium skirting / iprofayili ye-aluminium ekhokelwayo / iprofayili yokuhlobisa i-aluminium yenziwe nge-6063 ye-aluminium alloy.i-aluminiyam inxalenye ephambili.kwaye inxalenye eseleyo iya kuba njengezantsi.
Kwaye namhlanje siza kuchaza indima kunye nefuthe lezinto ezahlukeneyo kwi-aluminium alloys kwiipropati zezinto ze-aluminium.
ubhedu element
Xa inxalenye ye-aluminium-ecebileyo ye-aluminium-copper i-alloy yi-548, i-solubility ephezulu yobhedu kwi-aluminium yi-5.65%, kwaye xa ubushushu behla ukuya kwi-302, ukunyibilika kobhedu ngu-0.45%.Ubhedu luyinto ebalulekileyo yokudibanisa kwaye inesisombululo esithile esiqinileyo sokuqinisa.Ukongeza, i-CuAl2 iqiniswe kukuguga inefuthe elicacileyo lokomeleza ukwaluphala.Umxholo wethusi kwi-aluminium alloys ngokuqhelekileyo yi-2.5% ukuya kwi-5%, kwaye umphumo wokuqinisa ungcono xa umxholo wobhedu u-4% ukuya kwi-6.8%, ngoko umxholo wobhedu we-alloys ezininzi ezinzima ze-aluminium kuloluhlu.
Silicon element
Xa inxalenye ye-aluminium ecebileyo ye-Al-Si ye-alloy system ikwiqondo lokushisa kwe-eutectic ye-577 ° C, ubuninzi be-solubility ye-silicon kwisisombululo esiqinileyo yi-1.65%.Nangona ukunyibilika kuncipha ngokuhla kweqondo lobushushu, ezi ngxubevange azinyangeki bubushushu.Iialloyi ze-Al-Si zinamandla okulahla kunye nokuxhathisa umhlwa.
Ukuba i-magnesium kunye ne-silicon zongezwa kwi-aluminium ngexesha elifanayo ukwenza i-aluminium-magnesium-silicon alloy, isigaba sokuqinisa i-MgSi.Ubungakanani bobunzima be-magnesium kwi-silicon yi-1.73: 1.Xa uyila ukubunjwa kwe-alloy ye-Al-Mg-Si, umxholo we-magnesium kunye ne-silicon kufuneka ulungiswe ngokwalo mlinganiso kwi-substrate.Ezinye ii-alloys ze-Al-Mg-Si, ukwenzela ukuphucula amandla, zongeza umlinganiselo ofanelekileyo wobhedu, kwaye kwangaxeshanye wongeza inani elifanelekileyo lechromium ukuphelisa isiphumo esibi sobhedu ekuxhathiseni ukubola.
I-al-Mg2Si i-alloy alloy equilibrium yesigaba somzobo Ubuninzi be-solubility ye-Mg2Si kwi-aluminium kwi-aluminium ecebileyo inxalenye ye-1.85%, kwaye i-deceleration incinci ngokuhla kweqondo lokushisa.
Kwi-alloys ye-aluminiyam ekhubazekileyo, ukongezwa kwe-silicon kwi-aluminiyam yodwa kukhawulelwe kwizinto ze-welding, kwaye ukongezwa kwe-silicon kwi-aluminiyam nako kunempembelelo ethile yokomeleza.
I-Magnesium element
Inxalenye ye-aluminiyam etyebileyo yedayagram yesigaba sokulingana kwenkqubo ye-alloy ye-Al-Mg, nangona ijika le-solubility libonisa ukuba ukunyibilika kwe-magnesium kwi-aluminium kuncipha kakhulu ngokuhla kweqondo lobushushu, kodwa kuninzi lwe-alloys ye-aluminium ekhubazekileyo, umxholo we-magnesium. ingaphantsi kwe-6%.Umxholo we-silicon nawo uphantsi.Olu hlobo lwe-alloy alunakomelezwa ngonyango lobushushu, kodwa lukwazi ukuwelda kakuhle, ukuxhathisa okulungileyo kokubola, kunye namandla aphakathi.
Ukuqiniswa kwe-magnesium kwi-aluminium kubonakala.Kuzo zonke i-1% yokwanda kwe-magnesium, amandla okuqina aya kunyuka malunga ne-34MPa.Ukuba i-manganese yongezwa ngaphantsi kwe-1%, inokuncedisa umphumo wokuqinisa.Ngoko ke, emva kokongeza i-manganese, umxholo we-magnesium unokuncitshiswa, kwaye ngexesha elifanayo, ukuthambekela okutshisa okutshisayo kunokunciphisa.Ukongeza, i-manganese inokwenza i-Mg5Al8 ikhompawundi iqhube ngokulinganayo, kwaye iphucule ukunganyangeki komhlwa kunye nokusebenza kwe-welding.
IManganese
Ubuninzi be-solubility ye-manganese kwisisombululo esiqinileyo yi-1.82% xa ubushushu be-eutectic bungama-658 kumzobo wesigaba sokulinganisa se-Al-Mn alloy system.Amandla e-alloy ayanda ngokuqhubekayo kunye nokunyuka kwe-solubility, kwaye i-elongation ifikelela kwinqanaba eliphezulu xa umxholo we-manganese ngu-0.8%.I-al-Mn alloys ayi-alloys engenakuguga, oko kukuthi, ayinakomelezwa ngonyango lobushushu.
I-Manganese inokuthintela inkqubo yokubuyisela kwakhona i-aluminium alloy, inyuse ubushushu bokubuyisela kwakhona, kwaye inokuphucula kakhulu i-recrystallization grains.Ukucokiswa kweenkozo ezihlaziyiweyo ikakhulu ngenxa yesithintelo ekukhuleni kweenkozo ezihlaziyiweyo ngokusebenzisa amasuntswana asasaziweyo ekhompawundi ye-MnAl6.Omnye umsebenzi we-MnAl6 kukunyibilikisa isinyithi sokungcola ukwenza (Fe, Mn) Al6, ukunciphisa imiphumo eyingozi yentsimbi.
IManganese yinto ebalulekileyo yealluminiyam, enokuthi idityaniswe yodwa ukwenza ialloys yokubini iAl-Mn, kwaye idityaniswe rhoqo kunye nezinye izinto ezidibanisayo, ngoko ke uninzi lwealloyi zealuminiyam zinemanganese.
Zinc element
I-solubility ye-zinc kwi-aluminium yi-31.6% xa inxalenye ye-aluminium-ecebileyo ye-Al-Zn i-alloy system equilibrium diagram yesigaba se-275, kwaye ukunyibilika kwayo kwehla kwi-5.6% xa i-125.
Xa i-zinc yongezwa kwi-aluminium yodwa, ukuphuculwa kwamandla e-aluminium alloy phantsi kweemeko ze-deformation kuncinci kakhulu, kwaye kukho ukuthambekela koxinzelelo lwe-corrosion cracking, okunciphisa ukusetyenziswa kwayo.
I-Zinc kunye ne-magnesium yongezwa kwi-aluminium ngexesha elifanayo ukwenza isigaba sokuqinisa i-Mg / Zn2, esinempembelelo enkulu yokomeleza kwi-alloy.Xa umxholo we-Mg / Zn2 unyuka ukusuka kwi-0.5% ukuya kwi-12%, amandla okuqina kunye namandla okuvelisa anokunyuswa kakhulu.Umxholo we-magnesium udlula oko kufunekayo ukuze kuqulunqwe isigaba seMg / Zn2.Kwi-alloys ephezulu ye-aluminium, xa umlinganiselo we-zinc ukuya kwi-magnesium ulawulwa malunga ne-2.7, uxinzelelo lwe-corrosion cracking resistance ngowona mkhulu.
Ukuba ubhedu bongezwa kwi-Al-Zn-Mg ukwenza ialloyi ye-Al-Zn-Mg-Cu, umphumo wokomeleza i-matrix ngowona mkhulu phakathi kwazo zonke ii-alloys ze-aluminium, kwaye ikwayinto ebalulekileyo ye-aluminium alloy imathiriyeli kwi-aerospace, i-aviation industry, kunye nombane. ishishini lamandla.
