Khoom nthuav qhia:
Ntshiab tooj liab yog tooj liab nrog cov ntsiab lus ntau tshaj ntawm tooj liab, vim hais tias cov ntsiab lus tseem ceeb yog tooj liab ntxiv rau cov nyiaj, cov ntsiab lus yog 99.5 ~ 99.95%;lub ntsiab impurity: phosphorus, bismuth, antimony, arsenic, hlau, npib tsib xee, lead, hlau, tin, sulfur, zinc, oxygen, thiab lwm yam.;siv los ua cov khoom siv hluav taws xob, cov khoom siv tooj liab siab heev, tooj liab-raws li alloy.
Aluminium tooj dag tuaj yeem muab faib ua ob pawg.Ib qho yog casting tooj dag txhuas kom tshem tawm cov impurities thiab ua kom cov fluidity, cov hlau tsis tshaj 0.5%;Lwm qhov yog forging tooj dag txhuas kom muaj kev tiv thaiv corrosion, feem ntau siv los ua cov yeeb nkab condensing, feem ntau muaj pes tsawg leeg yog Al1 ~ 6%, Zn 24 ~ 42%, thiab Cu 55 ~ 71%.
