Fluidity yog hais txog lub peev xwm ntawm lub molten alloy los sau pwm. Lub℃ntawm fluidity txiav txim siab seb puas yuav siv tau cov hlau los nrum complex qhov chaw. Eutectic alloys pom qhov zoo tshaj plaws fluidity ntawm aluminium alloys.
Muaj ntau yam cuam tshuam rau fluidity, feem ntau muaj pes tsawg leeg, kub, thiab muaj cov khoom uas muaj hlau oxides, hlau compounds, thiab lwm yam kab mob nyob rau hauv lub molten alloy. Txawm li cas los xij, qhov tseem ceeb ntawm sab nraud yog qhov kub thiab txias (feem ntau hu ua lub taub hau pouring).
Hauv kev tsim khoom tiag tiag, muab cov khoom sib txuas ruaj khov, ntxiv rau kev ntxiv dag zog rau cov txheej txheem smelting (refining thiab slag tshem tawm), nws yog ib qho tseem ceeb los txhim kho cov pwm kev ua tau zoo (xuab zeb pwm permeability, hlau pwm venting thiab kub) thiab, tsis muaj kev cuam tshuam qhov zoo ntawm casting, nce qhov kub thiab txias kom ntseeg tau tias cov hlau nplaum fluidity.
