Collapse cov lus no feem ntau cov khoom
Cov phom uas siv hauv castings tuag yog cov khoom tsis yog fossous, thiab ferrous hlau (hlau, hlau, thiab lwm yam) tsis tshua siv vim muaj teeb meem xws li cov khoom pwm. Hauv cov yeeb nkab uas tsis yog fossous alloy tuag castings, aluminium alloys yog siv ntau dua, ua raws li cov zinc alloys. Cov nram no yog ib qho kev qhia me ntsis rau qhov teeb meem ntawm kev tuag-cam khwb cia hlau.
