Alloy Tsev Neeg thiab Kev Sib Sau
AW 7075 belongs rau 7xxx series ntawm txhuas-zinc-magnesium- tooj liab alloys. Nws yog cua sov kho tau thiab txhim kho ultra- lub zog siab los ntawm nag lossis daus hardening, nrog zinc ua lub ntsiab alloying, ntxiv los ntawm magnesium, tooj liab, thiab chromium. Qhov sib xyaw no ua rau muaj zog tensile thiab tawm los, ua rau cov hlau zoo tagnrho rau cov ntawv thov uas xav tau kev ua haujlwm siab tshaj plaws. AW 5083 belongs rau 5xxx series ntawm txhuas{11}}magnesium alloys. Nws tsis yog -kub- kho tau thiab tau txais nws lub zog los ntawm kev sib zog ua kom tawv nqaij, nrog magnesium ua lub ntsiab alloying. Nws muaj pes tsawg leeg muab zoo heev corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv seawater thiab av ib puag ncig, thaum tuav zoo zog thiab ductility.
Mechanical Properties Sib piv
7075 txhuas phaj muaj lub zog siab heev thiab tawv tawv hauv nws cov cua sov- kho tempers, uas yog vim li cas nws dominates aerospace, tiv thaiv, thiab precision machinery daim ntaub ntawv qhov chaw load- bearing muaj peev xwm thiab nruj yog ib qho tseem ceeb heev . 5083 txhuas phaj hais txog corrosion kuj, toughness, thiab qaug zog tsis kam es tsis muaj zog peak. Nws qhov kev sib xyaw ua ke ntawm nruab nrab- rau- lub zog siab nrog kev tawg zoo heev ua rau nws nyiam cov khoom siv rau kev tsim cov nkoj, cov qauv hauv hiav txwv, thiab cov ntug dej hiav txwv, qhov twg ntev - lub sij hawm kev ntseeg siab hauv kev pabcuam corrosive tseem ceeb tshaj qhov kev ua haujlwm siab tshaj plaws.
Corrosion Resistance
AW 5083 excels nyob rau hauv marine corrosion kuj, withstanding ntev - lub sij hawm raug rau dej hiav txwv, ntsev tsuag, thiab av noo ib puag ncig. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau nkoj hulls, decks, bulkheads, thiab offshore structures. AW 7075 muaj qhov nruab nrab corrosion kuj: nws ua tau zoo nyob rau hauv kev tswj los yog qhuav ib puag ncig, tab sis ntev raug rau seawater tuaj yeem ua rau corrosion tshwj tsis yog siv cov txheej tiv thaiv los yog anodizing. Thaum xaiv ntawm ob, qhov chaw pabcuam feem ntau yog qhov kev txiav txim siab.
