Hardness ntawm tooj dag

Ib txwmtooj dagNws yog ib qho alloy ntawm tooj liab thiab zinc.Thaum cov ntsiab lus zinc tsawg dua 39%, zinc tuaj yeem yaj hauv tooj liab los ua ib theem ib, hu ua ib-theem tooj dag, uas muaj cov yas zoo thiab tsim nyog rau kev ua haujlwm kub thiab txias.Thaum cov zinc cov ntsiab lus ntau dua 39%, muaj ib theem thiab b cov khoom siv tshuaj raws li tooj liab thiab zinc, hu ua dual-theem tooj dag, b ua rau cov yas me me thiab lub zog tensile nce, uas tsuas yog tsim nyog rau kev ua haujlwm kub. .Yog hais tias qhov loj feem ntawm zinc tseem nce ntxiv, lub zog tensile yuav txo qis, thiab cov lej yuav raug suav hais tias yog "H + tus lej", H sawv cev rau tooj dag, thiab tus lej sawv cev rau feem ntau ntawm tooj liab.Piv txwv li, H68 qhia tias cov ntsiab lus tooj liab yog 68%, thiab cov ntsiab lus zinc yog 32%.Rau tooj dag, cov cam khwb cia tooj dag yuav tsum muaj lo lus "Z" ua ntej tus lej, xws li ZH62, xws li Zcuzn38, uas qhia tias zinc cov ntsiab lus yog 38%, thiab qhov sib npaug yog tooj liab.Casting tooj dag.H90 thiab H80 yog ib theem, kub daj, yog li lawv hu ua kub, uas yog hu ua coatings, decorations, medals, thiab lwm yam. H68 thiab H59 yog ib tug duplex tooj dag, uas yog dav siv nyob rau hauv cov qauv ntawm cov khoom siv hluav taws xob, xws li bolts. , txiv ntseej, washers, springs, thiab lwm yam. Feem ntau, ib leeg-theem tooj dag rau txias deformation ua thiab dual-theem tooj dag rau kub deformation ua.2) Cov tooj dag tshwj xeeb Ib qho khoom sib xyaw ua ke ntawm lwm cov alloying ntxiv rau cov tooj dag zoo tib yam hu ua tooj dag.Feem ntau ntxiv cov ntsiab lus yog txhuas, tin, txhuas, thiab lwm yam, uas tuaj yeem hu ua tooj dag, tooj dag, thiab txhuas tooj dag raws li.Lub hom phiaj ntawm kev ntxiv alloying ntsiab.Lub hom phiaj tseem ceeb yog txhawm rau txhim kho lub zog tensile thiab txhim kho kev tsim khoom.Xws li: HPb59-1 txhais tau hais tias qhov loj feem ntawm tooj liab yog 59%, qhov loj feem ntawm cov ntsiab lus tseem ceeb yog 1%, thiab qhov sib npaug yog tooj liab nrog zinc.
