tin bronze 6-6-3 thiab 5-5-5 puas tuaj yeem hloov tau rau ib leeg?
Tin bronze {{0}}} los ntawm lub teb chaws tus qauv GB 1176-74 "Technical Conditions for Cast Copper Alloys" tshaj tawm rau xyoo 1974. Tus qauv tom qab tau hloov los ntawm lub teb chaws tus qauv GB 1176-87 " Cov xwm txheej txheej txheem rau Cast Copper Alloys" tau kho dua xyoo 1987. Txij li GB 1176-87 tus qauv rau cam khwb cia tooj liab alloys, tsis muaj ZQSn6-6-3. Qhov zoo sib xws yog ZQSn5-5-5 (ZQSn5Pb5Zn5), nrog cov tshuaj muaj pes tsawg leeg ntawm Sn4.0~6.0%, Pb4.0~6.{{21} }%, Zn4.0-6.0%, thiab tooj liab tshuav nyiaj li cas. Tus qauv tshiab kawg yog GB∕T 1176-2013 Cast Copper thiab Copper Alloys tau kho dua xyoo 2013.
Vim tias ob qho tib si muaj cov khoom sib xws thiab cov khoom sib xws, Tin Bronze 6-6-3 thiab Tin Bronze 5-5-5 tuaj yeem siv sib hloov raws li kev ua haujlwm dav dav. Raws li kev ua haujlwm tshwj xeeb, lawv yuav tsum ua raws li cov qauv tsim thiab kos duab.
Tin bronze yog qhov ntxov tshaj plaws nonferrous alloy siv nyob rau hauv kuv lub teb chaws keeb kwm thiab kuj yog ib qho ntawm feem ntau siv nonferrous alloys. Tin bronze feem ntau yog siv los tsim cov castings nrog cov duab complex, meej contours, thiab tsis tshua muaj airtightness.
Cov yam ntxwv ntawm tin bronze muaj feem xyuam nrog cov ntsiab lus tin. Thaum cov ntsiab lus tin nyob rau hauv tin bronze nce, lub plasticity ntawm tin bronze yuav txo qis, nws yuav ua ntau thiab nkig, thiab lub zog yuav maj mam txo. Tau kawg, ntxiv rau tin, tin bronze feem ntau muaj lwm yam me me ntawm cov ntsiab lus, xws li zinc, lead, phosphorus, thiab lwm yam. Ntawm lawv, zinc tuaj yeem txhim kho cov khoom siv dag zog thiab fluidity ntawm low-tin bronze. Lead tuaj yeem txhim kho qhov hnav tsis kam thiab kev ua haujlwm ntawm bronze.
