Tin, txhuas, zinc, txhuas, magnesium, tooj liab, thiab lwm yam ntaub ntawv alloy yog cov khoom siv feem ntau siv hauv kev tuag casting. Cov alloys nrov tshaj plaws yog ua los ntawm zinc thiab txhuas, ua raws li tooj liab thiab magnesium alloys. Lub sijhawm no, cov khoom siv hluav taws xob feem ntau siv cov alloys ua los ntawm zinc, aluminium, thiab magnesium.
Zinc alloy tuag-casting
Lub melting point ntawm zinc alloy yog tsawg li 365 degrees, thiab nws muaj zoo fluidity nyob rau hauv lub molten mob. Muaj ntau cov txheej txheem tom qab ua tiav uas yuav siv tau, suav nrog electroplating. Yog li ntawd, nws muaj ob peb daim ntawv thov. Nws yog ib zaug siv hnyav heev hauv lub xov tooj ntawm tes thiab, tab sis vim nws qhov sib piv siab thiab subpar corrosion kuj, aluminium alloys tau hloov pauv ntau ntxiv. Kev lag luam huv huv tam sim no yog ib qho uas siv nws tshaj plaws. Alloys 2, 3, 4, 5, thiab 7 feem ntau yog ua haujlwm, nrog alloy 3 yog qhov nrov tshaj plaws tam sim no.
Aluminium alloy tuag-casting
Aluminium alloy muaj qhov ntom ntom tab sis muaj zog uas piv rau lossis ntau dua li cov hlau zoo. Nws tuaj yeem ua tiav rau ntau qhov sib txawv thiab muaj plasticity siab. Nws muaj zoo corrosion kuj, thermal conductivity, thiab hluav taws xob conductivity. Nws yog thib ob tsuas yog steel raws li tus nqi ntawm kev siv hauv kev lag luam. Txij li thaum aluminium alloy muaj qhov hnyav tshwj xeeb uas tsuas yog nyob ib ncig ntawm ib feem peb ntawm cov hlau, nws tau siv dav thoob plaws hauv zej zog, tshwj xeeb tshaj yog rau cov tsheb sib zog, cov khoom siv hluav taws xob, dav hlau, thiab nkoj.
Al-Si-Cu series yog siv dav tshaj plaws, thiab piv txwv suav nrog ADC12 (A383), ADC10 (A380), thiab lwm yam. Al-Si series, Al-Si-Mg series, thiab Al-Mg series yog ntxiv. Tsis tas li ntawd, los ntawm kev ntxiv titanium hlau rau cov lus hais saum toj no, dab tsi yog tam sim no hu ua aluminium-titanium alloy yog txhim kho. Cov cuab yeej zoo ntawm cov khoom tuaj yeem txhim kho zoo heev los ntawm kev siv titanium hlau.
Magnesium alloy tuag casting
Ib qho hlau ua los ntawm magnesium thiab lwm yam khoom hu ua magnesium alloy. Nws muaj qhov ntom ntom dua li aluminium alloy, lub zog tshwj xeeb dua, qhov loj dua elastic modulus, zoo cua sov dissipation, muaj zog poob siab absorbing, muaj peev xwm ntau dua load peev xwm, thiab zoo kuj rau cov organic teeb meem thiab alkali corrosion. Magnesium muaj ib lub ntiajteb txawj nqus uas nyob ib ncig ntawm ob feem peb ntawm txhuas thiab ib feem plaub ntawm hlau. Yog li ntawd, nws nquag siv hauv cov khoom siv kho mob, cov khoom siv hauv tsheb, cov khoom siv sib txuas lus, thiab lwm yam khoom siv hluav taws xob.
Qhov nrov tshaj plaws magnesium alloys tam sim no yog magnesium-aluminium alloys, ua raws li magnesium-manganese alloys thiab magnesium-zinc-zirconium alloys. Cov qib zoo li AZ91D, AM60B, AM50A, AS41B, thiab lwm yam yog feem ntau siv.
