Aluminium yog ib qho ntawm cov hlau uas Z tsis yooj yim rau corrode. Cov khoom siv aluminium alloy siv hauv dej hiav txwv yog dav siv hauv nkoj vim nws tsis tshua muaj corrosiveness. Aluminium alloy tsis muaj hlau thiab hlau, yog li nws yuav tsis xeb. Yog lawm, txhuas kuj tseem yuav raug oxidation, tab sis thaum lub sij hawm oxidation txheej txheem, ib txheej tawv tawv ntawm txhuas oxide yuav raug tsim los tiv thaiv cov ntaub ntawv hauv qab los ntawm kev txuas ntxiv mus. Yog tias tsim nyog siv aluminium alloy thiab vuam hlau, kev tsim qauv, thiab kev saib xyuas tsis tu ncua, aluminium yacht tuaj yeem nyob tau ntau xyoo.
