1. tooj dag
(1) Ordinary tooj dag: Nws yog ib qho alloy uas muaj tooj liab thiab zinc. Thaum cov ntsiab lus zinc tsawg dua 39%, zinc tuaj yeem yaj hauv tooj liab los ua ib theem ib, uas yog hu ua ib-theem tooj dag. Nws muaj cov yas zoo thiab tsim nyog rau kev ua haujlwm kub thiab txias. Thaum cov ntsiab lus zinc ntau dua 39%, muaj ib theem ib thiab ib qho kev daws teeb meem b raws li tooj liab thiab zinc, uas yog hu ua dual-theem tooj dag. b ua rau lub plasticity tsawg thiab lub zog tensile siab. Nws tsuas yog tsim rau kev kub siab ua haujlwm. Yog hais tias qhov loj feem ntawm zinc tseem nce ntxiv, lub zog tensile txo qis thiab nws tsis muaj nqi siv. Tus lej yog sawv cev los ntawm "H + tus lej", H sawv cev rau tooj dag, thiab tus lej sawv cev rau feem ntau ntawm tooj liab. Piv txwv li, H68 sawv cev rau tooj dag nrog tooj liab cov ntsiab lus ntawm 68% thiab zinc ntsiab lus ntawm 32%. Cam khwb cia tooj dag muaj "Z" ua ntej tus lej, xws li ZH62. Piv txwv li, Zcuzn38 sawv cev rau cam khwb cia tooj dag nrog zinc ntsiab lus ntawm 38% thiab cov seem yog tooj liab. H90 thiab H80 yog ib theem thiab kub daj, yog li lawv tau sau ua ke hu ua kub, thiab hu ua plating, decorations, medals, thiab lwm yam. H68 thiab H59 yog cov tooj dag duplex, uas yog siv dav hauv cov khoom siv hluav taws xob, xws li bolts, txiv ntseej, ntxhua khaub ncaws, springs, thiab lwm yam. Feem ntau, ib leeg-theem tooj dag yog siv rau txias deformation ua thiab duplex tooj dag yog siv rau kub deformation ua.
(2) Cov tooj dag tshwj xeeb: Cov khoom siv sib xyaw ua ke ntawm lwm cov khoom sib txuas ntxiv rau cov tooj dag zoo tib yam hu ua tooj dag. Feem ntau cov khoom ntxiv muaj xws li txhuas, tin, txhuas, thiab lwm yam, uas tuaj yeem hu ua txhuas tooj dag, tooj dag, thiab txhuas tooj dag raws li. Lub hom phiaj ntawm kev ntxiv cov ntsiab lus alloying. Nws yog tsuas yog los txhim kho tensile lub zog thiab processability. Code: "H + lub cim ntawm lub ntsiab tseem ceeb ntxiv (tshwj tsis yog zinc) + pawg loj ntawm tooj liab + pawg pawg ntawm cov ntsiab lus ntxiv + pawg loj ntawm lwm cov ntsiab lus". Piv txwv li, HPb 59-1 txhais tau hais tias cov tooj dag txhuas nrog ib feem ntawm 59% tooj liab, ib feem ntawm 1% ntawm cov ntsiab lus tseem ceeb ntxiv, thiab cov seem yog zinc.
