5083 txhuas raj yog ib hom aluminium alloy tubing raws li aluminium-magnesium alloy, uas nws cov khoom tseem ceeb suav nrog txhuas (Al), magnesium (Mg), manganese (Mn), silicon (Si) thiab lwm yam khoom me me. Tshwj xeeb, cov khoom tseem ceeb ntawm 5083 aluminium alloy yog kwv yees li hauv qab no:
1. Aluminium (Al): qhov feem ntau yog ntau tshaj 90%, yog qhov tseem ceeb ntawm cov txhuas raj, kom nws muaj cov yam ntxwv zoo sib xws.
2. magnesium (Mg): cov ntsiab lus feem ntau yog nruab nrab ntawm 3.0% thiab 4.5%, magnesium raws li cov khoom siv hlau tuaj yeem txhim kho lub zog thiab corrosion tsis kam ntawm aluminium alloy, tab sis kuj txhim kho nws cov ductility thiab weldability.
3. manganese (Mn): cov ntsiab lus feem ntau yog nruab nrab ntawm 0.4% thiab 1.0%, manganese tuaj yeem txhim kho lub zog thiab oxidation tsis kam ntawm aluminium alloy.
4. silicon (Si): cov ntsiab lus feem ntau tsis tshua muaj, feem ntau tsis ntau tshaj 0.4%, feem ntau yog los txhim kho cov khoom pov thawj ntawm aluminium alloys.
5. lwm cov ntsiab lus: xws li tooj liab (Cu), zinc (Zn) thiab hlau (Fe), thiab lwm yam, cov ntsiab lus me me, feem ntau yog siv los ua kom zoo dua cov khoom siv thiab kev ua haujlwm.
