5083 Aluminium Phaj

 

5083 txhuas daim hlau yog cov muaj zog aluminium alloys feem ntau yog tsim los ntawm txhuas, magnesium, thiab cov lej ntawm manganese thiab chromium. Cov alloy muaj lub zog tensile ntawm ib ncig ntawm 275-350 MPa, nrog lub zog tawm los ntawm kwv yees li 125-275 MPa, nyob ntawm qhov npau taws. Tsis tas li ntawd, nws muaj Brinell hardness ntawm 75 HB, thiab qhov ceev ntawm kwv yees li 2.66 g / cm³. Cov hlau tseem qhia tau zoo thermal conductivity nyob ib ncig ntawm 117 W / m·K, kom ntseeg tau tias muaj kev kub ntxhov hauv ntau daim ntawv thov, thaum nws cov thermal expansion coefficient yog 24.2 µm / m·K, qhia txog kev nthuav dav nrog qhov kub thiab txias.

 

 

Corrosion Resistance
Cov cuab yeej no yog los ntawm cov ntsiab lus magnesium siab hauv 5083 txhuas, uas tsim cov txheej txheem oxide passive rau ntawm qhov chaw, tiv thaiv cov khoom los ntawm corrosion, tshwj xeeb tshaj yog nyob rau hauv saline lossis tshuaj lom neeg hnyav. Qhov no txo ​​cov nqi txij nkawm thiab txuas ntxiv lub neej ntawm cov qauv raug dej, xws li cov nkoj thiab cov ntug dej hiav txwv. Nws yog dav siv nyob rau hauv shipbuilding, marine Cheebtsam, thiab chemical processing tanks uas ntev raug rau corrosive ib puag ncig zoo li seawater yuav tsum.

 

Siab zog
Cov ntsiab lus alloying xws li magnesium, manganese, thiab chromium pab txhawb lub zog ntawm 5083 txhuas los ntawm kev hloov nws cov microstructure. Cov magnesium atoms distort aluminium lattice, ua rau nws nyuaj rau dislocations txav, uas ua rau cov alloy tag nrho lub zog. Manganese thiab chromium tsim intermetallic tebchaw nrog txhuas uas ua rau muaj kev cuam tshuam rau kev txav mus los, ntxiv dag zog rau cov hlau muaj peev xwm tiv taus kev ntxhov siab. Qhov kev sib xyaw ua ke ntawm cov ntsiab lus sib xyaw ua kom ntseeg tau tias cov khoom siv tuaj yeem tiv taus kev ntxhov siab thiab thauj khoom yam tsis muaj deformation, ua rau nws muaj kev ntseeg siab heev hauv kev xav tau. Nws yog qhov zoo tagnrho rau kev tsim cov hlab ntsha siab, lub cev lub cev, thiab cov qauv thauj khoom hauv cov nkoj, qhov chaw muaj zog yog qhov tseem ceeb rau kev nyab xeeb.

 

Weldability zoo
5083 aluminium muaj qhov tsis tshua muaj kev tawg yooj yim thaum lub sij hawm vuam ntau vim nws cov ntsiab lus magnesium siab. Magnesium nyob rau hauv cov alloy pab tiv thaiv kev loj hlob ntawm kub tawg. Kub tawg, tseem hu ua solidification cracking, tshwm sim thaum cov khoom txias thiab solidifies unevenly, ua rau muaj kev ntxhov siab thiab puas. Qhov no ua kom ntseeg tau tias cov pob qij txha welded khaws lawv lub zog tom qab vuam yam tsis xav tau kev kho cua sov ntxiv, ua kom yooj yim rau kev tsim cov txheej txheem. Qhov no ua rau 5083 txhuas zoo tagnrho rau cov qauv welded xws li nkoj hulls, cia tso tsheb hlau luam, thiab cov kav dej, qhov twg vuam efficiency thiab muaj peev xwm khaws tau lub zog ntawm cov pob qij txha yog qhov tseem ceeb rau kev ncaj ncees.

 

Hardness
Brinell hardness ntawm 5083 txhuas yog kwv yees li 75 HB, uas muab kev hnav tsis kam. Cov qib hardness no tshwm sim los ntawm cov hlau sib npaug sib npaug, tshwj xeeb tshaj yog nws cov ntsiab lus magnesium thiab manganese, uas ntxiv dag zog rau aluminium matrix thiab txhim kho nws lub peev xwm los tiv thaiv deformation thiab abrasion. Nyob rau hauv kev lag luam machinery, 5083 txhuas daim hlau yog siv rau qhov chaw xws li conveyor siv thiab rollers nyob rau hauv tas li ntawd mus rau lwm yam ntaub ntawv. Nyob rau hauv ib puag ncig marine, nws yog siv nyob rau hauv cov khoom xws li hulls thiab lawj cov qauv, uas raug rau abrasive quab yuam los ntawm dej thiab cov khoom me me.
