Daim ntawv thov loj tshaj plaws ntawm magnesium yog qhov sib ntxiv ntawm cov ntsiab lus rau aluminium alloys.Lub hom phiaj tseem ceeb yog los txhim kho ntau yam kev ua tau zoo ntawm aluminium alloy tuag castings, tshwj xeeb tshaj yogcorrosion kuj.
Raws li cov kws tshaj lij, aluminium-magnesium alloy tuag-casting yog lub teeb thiab nyuaj, muaj kev tiv thaiv corrosion zoo, yooj yim rau vuam thiab lwm yam kev kho saum npoo, thiab yog cov khoom tseem ceeb rau kev tsim aircraft, foob pob ua ntxaij, speedboats, tsheb, thiab lwm yam Raws li kev txheeb cais. , ntau tshaj 45% ntawm magnesium yog siv los ua ib qho khoom siv ntxiv rau txhuas alloys hauv Tebchaws Meskas txhua xyoo, thiab magnesium kuj tseem siv ntau npaum li cov khoom siv ntxiv rau aluminium alloys hauv Suav teb.Tsis tas li ntawd, magnesium yog ntxiv rau zinc tuag-cam khwb cia alloys kom nws lub zog thiab txhim kho qhov ntev stability.
Nws yog cov hlau lightest hauv kev siv tswv yim, thiab lub ntiajteb txawj nqus ntawm magnesium yog hais txog 2/3 ntawm txhuas thiab 1/4 ntawm cov hlau.Nws yog lub lightest hlau ntawm cov tswv yim hlau, nrogsiab zogthiabsiab rigidity.Tam sim no, feem ntau siv yog magnesium-aluminium alloy, ua raws li magnesium-manganese alloy thiab magnesium-zinc-zirconium alloy.Magnesium alloys yog dav siv nyob rau hauv cov khoom siv portable thiab tsheb industries rauua tiav lub hom phiaj ntawm lub teeb yuag.
Lub melting point ntawm magnesium alloy yog qis duadua li ntawm aluminium alloy, thiab covtuag-casting kev ua tau zoo.Lub zog tensile ntawm magnesium alloy castings yog sib npaug rau cov aluminium alloy castings, feem ntau mus txog 250MPA, thiab mus txog ntau tshaj 600Mpa.Lub zog tawm los thiab elongation tsis txawv ntau ntawm cov aluminium alloys.
Magnesium alloy kuj muajzoo corrosion kuj, electromagnetic shielding kev ua tau zoo, hluav taws xob tiv thaiv kev ua haujlwm, thiab tuaj yeem yog100% rov siv dua.Nws yog nyob rau hauv txoj kab nrog lub tswvyim ntawm ntsuabkev tiv thaiv ib puag ncigthiabkev tsim kho kom ruaj khov.
