Dab tsi yog qhov ceev ntawm tin bronze?

Tin toojQhov ceev tshwj xeeb gravity ρ (8.82).Bronze yuav muab faib ua ob pawg: tin bronze thiab tshwj xeeb bronze (ie Wuxi bronze).Rau cov khoom siv casting, ntxiv lo lus "Z" ua ntej tus lej, xws li: Qal7 txhais tau tias cov ntsiab lus txhuas yog 5%, thiab tus so yog tooj liab.Tooj liab casting tin bronze Tin bronze yog tooj liab-tin alloy nrog tin raws li lub ntsiab tseem ceeb, tseem hu ua tin bronze.Thaum cov ntsiab lus tin tsawg dua 5 ~ 6%, tin dissolves nyob rau hauv tooj liab los ua ib qho kev daws teeb meem, thiab cov yas nce ntxiv.Thaum cov nyiaj ntau dua 5 ~ 6%, lub zog tensile txo vim qhov pom ntawm Cu31sb8-raws li cov tshuaj tov, yog li cov ntsiab lus ntawm cov nplai tin bronze feem ntau ntawm 3 ~ 14%.Thaum cov ntsiab lus tin tsawg dua 5%, nws tsim nyog rau txias.Deformation ua, thaum cov ntsiab lus tin yog 5-7%, nws yog tsim rau kub deformation ua.Thaum cov ntsiab lus tin ntau tshaj 10%, nws yog tsim rau casting.Txij li thaum lub peev xwm ntawm ib thiab & zoo sib xws, thiab cov tin nyob rau hauv cov muaj pes tsawg leeg yog nitrided los ua ib tug tuab tin dioxide zaj duab xis, corrosion kuj ntawm cov huab cua thiab dej hiav txwv yog zoo dua, tab sis cov acid kuj tsis zoo.Vim hais tias tin bronze muaj qhov kub thiab txias ntau ntau thiab cov dej tsis zoo, nws tsis yooj yim rau kev tsim cov pob txha pob txha, tab sis nws yog ib qho yooj yim los tsim dendrite segregation thiab dispersed shrinkage qhov.Cov duab tsis yooj yim.Cov xwm txheej ntawm cov phab ntsa loj loj tsis haum rau cov castings uas yuav tsum tau muaj siab ceev thiab zoo sealing.Tin bronze muaj qhov zoo tiv thaiv kev sib txhuam, tiv thaiv kev sib nqus thiab tsis tshua muaj kub toughness.
