Kev Txhais Ntawm Aluminium Ua

Txhuas ua, aluminium ingot tiav rau hauv cov khoom siv los ntawm kev siv yas ua cov txheej txheem, thiab cov hau kev tseem ceeb yog dov, extrusion, kos duab thiab forging. Txhuas ua tau pib thaum ntxov xyoo pua 20 hauv kev lag luam kev tsim khoom. Ua ntej xyoo 1930, nws yog ib txwm siv cov khoom siv tooj liab, uas yog siv dav hlau hauv kev tsim khoom. Tom qab xyoo 1960, kev tsim kho aluminium tau tshwm sim sai heev, nce li ntawm 4 txog 8% hauv ib xyoos. Cov khoom siv tau dav siv hauv aviation, kev tsim kho, tsheb thauj mus los, hluav taws xob, tshuaj lom neeg, ntim thiab kev lag luam kev lag luam. Cov zis yog thib ob tsuas yog rau steel thiab Qib thib ob hauv cov hlau. Nyob rau lub sijhawm xyoo 1950, Suav teb txhim kho cov txhuas ua cov khoom lag luam loj dua thiab tsim kev tsim ntau lawm. Cov khoom lag luam tau txheeb thiab ntau hom muaj xya qhov sib xyaw, uas tuaj yeem tsim cov phaj, txaij, ntawv ci, kav dej, tuav, cov khoom siv, xov hlau thiab zam. (Kev zam dawb, zam kev tuag) yim yam khoom.
