Fluidity yog hais txog lub peev xwm ntawm cov kua alloy los sau cov pwm. Qhov loj ntawm qhov fluidity txiav txim siab seb cov hlau puas tuaj yeem nrum nyuaj castings. Lub fluidity ntawm eutectic alloys yog qhov zoo tshaj plaws nyob rau hauv aluminium alloys.
Muaj ntau ntau yam uas cuam tshuam rau lub fluidity, feem ntau yog cov muaj pes tsawg leeg, qhov kub thiab txias ntawm cov hlau oxides, hlau compounds thiab lwm yam kuab paug nyob rau hauv cov kua alloy, tab sis cov ntsiab lus tseem ceeb sab nraud yog qhov kub thiab txias (feem ntau hu ua pouring taub hau. ) qib.
Hauv kev tsim khoom tiag tiag, thaum cov hlau tau raug txiav txim siab, ntxiv rau kev ntxiv dag zog rau cov txheej txheem smelting (refining thiab slag tshem tawm), nws tseem tsim nyog los txhim kho cov txheej txheem casting (xuab zeb pwm permeability, hlau pwm tso tawm thiab kub), thiab tsis cuam tshuam rau. lub premise ntawm casting zoo, lub pouring kub yog nce los xyuas kom meej lub fluidity ntawm lub alloy.
