Kev xaiv cov khoom siv rau cov khoom siv hauv tsev tuag- cov khoom pov thawj cuam tshuam ncaj qha rau cov khoom lag luam, cov nqi tsim khoom, thiab cov txheej txheem ua tom ntej. Cov khoom siv hlau feem ntau siv rau kev tuag casting suav nrog txhuas alloys, zinc alloys, thiab magnesium alloys, txhua qhov tshwj xeeb zoo thiab cov xwm txheej siv tau.
Aluminium alloys yog dav siv nyob rau hauv casings thiab tshav kub dissipation Cheebtsam ntawm cov khoom loj hauv tsev xws li cov cua txias thiab tub yees vim lawv lub teeb yuag, siab zog, thiab zoo corrosion kuj. Zinc alloys muaj fluidity zoo thiab nto tiav, ua rau lawv tsim nyog rau kev tsim me me, precision qhov chaw xws li hloov panels thiab tes. Magnesium alloys, nrog rau lawv qhov hnyav hnyav thiab zoo thermal conductivity, yog siv nyob rau hauv siab -kawg cov khoom siv hauv tsev thiab cov khoom siv nqa tau yooj yim, tab sis lawv kim dua thiab yuav tsum tau tswj cov txheej txheem nruj.
Nyob rau hauv cov nqe lus ntawm cov ntaub ntawv kev ua tau zoo, txhua yam khoom, coefficient ntawm thermal expansion, corrosion kuj, thiab machinability yuav tsum tau muab xam tag nrho.
Cov cuab yeej siv hauv tsev tuag- cov khoom pov tseg feem ntau yuav tsum tau tiv taus qee yam khoom siv, xws li tshuab ntxhua khaub ncaws lub cev thiab lub qhov cub microwave; Yog li ntawd, lub zog tawm los thiab tensile lub zog ntawm cov khoom yog cov cim tseem ceeb. Ib txhij, cov coefficient ntawm thermal expansion cuam tshuam qhov haum ntawm cov khoom thiab lwm yam ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv multi- cov khoom sib dhos hauv tsev. Tsim nyog sib piv cov coefficients ntawm thermal expansion ntawm cov ntaub ntawv yuav tiv thaiv deformation los yog tawg los ntawm thermal stress. Corrosion kuj tseem ceeb heev. Cov khoom siv hauv chav ua noj, lub tshuab cua txias condensate ntws cov kav dej, thiab lwm yam khoom uas muaj kev sib cuag nrog dej los yog qhov chaw ntub dej yuav tsum tau ceev faj xaiv cov khoom siv los yog kev kho saum npoo kom ntseeg tau lub neej ntev.
Dhau li ntawm cov yam ntxwv ntawm cov hlau, lub machinability ntawm cov khoom kuj yog ib qho tseem ceeb ntawm cov khoom xaiv. Aluminium thiab zinc alloys muaj cov ntsiab lus melting tsawg thiab zoo fluidity, ua rau lawv haum rau siab -speed tuag casting; magnesium alloys, thaum lub teeb yuag, yog flammable thiab yuav tsum tau nruj txheej txheem kev nyab xeeb. Tsis tas li ntawd, cov khoom sib txawv muaj qhov sib txawv ntawm qhov sib txawv, thiab cov nyiaj shrinkage yuav tsum tau txiav txim siab thaum tsim pwm los xyuas kom meej qhov tseeb ntawm qhov chaw.
