Qhov sib txawv ntawm tooj dag, tin tooj liab thiab tooj liab liab
Cov tooj liab ntshiab yog cov xim liab liab liab, uas yog xim paj yeeb tom qab tsim cov tooj liab oxide zaj duab xis rau saum npoo, yog li tooj liab ntshiab yog feem ntau hu ua tooj liab liab lossis tooj liab tooj liab. Qhov ntom ntom yog 8-9g / cm3 thiab lub ntsiab lus yaj yog 1083 ° C。 Ntshiab tooj liab muaj cov coj zoo thiab yog siv dav hauv kev tsim cov xov hlau, kab hluav taws xob, txhuam, thiab lwm yam; Nrog cov thermal conductivity zoo, feem ntau siv los ua cov khoom sib nqus thiab cov ntsuas, xws li cov khoom siv hluav taws xob thiab cov chaw ya, uas yuav tsum muaj kev tiv thaiv los ntawm kev sib nqus; Kev siv yas zoo heev, yooj yim kom kub xovxwm thiab txias nias txheej txheem, tuaj yeem ua rau raj, bar, hlau, plhaw, sawb, phaj, ntawv ci thiab lwm yam tooj liab.
Cov tooj dag yog ib qho sib txuas ntawm tooj liab thiab zinc. Cov tooj dag yooj yim tshaj plaws yog tooj liab zinc binary alloy, uas yog hu ua tooj dag yooj yim lossis tooj dag zoo nkauj. Cov tooj dag nrog cov cuab yeej sib txawv muaj peev xwm muab tau los ntawm kev hloov cov ntsiab lus ntawm zinc hauv tooj dag. Cov ntsiab lus siab dua ntawm zinc hauv tooj dag, lub zog siab dua thiab qis dua plasticity. Cov ntsiab lus zinc ntawm tooj dag uas siv hauv kev lag luam tsis ntau tshaj 45%. Tsis muaj teeb meem npaum li cas cov ntsiab lus zinc siab, brittleness yuav tshwm sim thiab cov alloy zog yuav tsis zoo.
Tin tooj yog ib qho ntawm qhov pib siv alloys hauv keeb kwm. Nws Ameslikas hais txog tooj liab tin alloy. Vim tias nws cov xim dawb xiav txho, nws hu ua tooj liab. Cov tooj yajthem muaj cov cuab yeej zoo, tiv thaiv kev xeb zoo, ua rau thaiv kev ua haujlwm thiab cov khoom zoo casting; Nws muaj qhov tsis tshua muaj siab zoo rau kev ua kom sov thiab roj, qhov weldability zoo, tsis muaj ferromagnetism thiab qis shrink coefficient. Qhov kev xeb kev cuam tshuam ntawm cov xeb tooj liab yog siab dua qhov uas tooj dag hauv cua, dej hiav txwv, dej tshiab thiab chav.
