Qhia luv luv ntawm Main Tin Bronze Castings ntawm Japanese Standard
Bronze castings (bronze) yog tooj liab alloys uas tau siv dav hauv ntau qhov chaw vim lawv qhov zoo corrosion kuj, siab tsis kam thiab cov khoom siv kho tshuab.
Nws kuj muaj qhov tawv tawv thiab tau siv los ua cov phom phom kom txog thaum xyoo 1900s, yog li nws tseem hu ua phom tooj liab.
Bronze castings muaj xws li tooj liab-tin-zinc alloy bronze castings hom 2, tooj liab-tin-zinc alloy bronze castings hom 3, thiab lead-added tooj liab-tin-zinc-lead alloy bronze castings hom 1, hom 6, hom 7 thiab hom 8 .
Nws tau muab faib ua 11 hom bronze castings ua los ntawm Cu-Sn-Zn-Ni-S alloys dispersed nrog sulfides.
CAC402 thiab CAC403 muaj lub siab ua haujlwm zoo, hnav tsis kam thiab cov khoom siv dag zog ntawm cov bronze castings, thiab muaj cov dej hiav txwv zoo tshaj plaws ntawm cov bronzes.
Yog li ntawd, lawv tau siv dav hauv bushings thiab lub tes tsho rau cov nkoj thiab cov khoom siv dav dav.
CAC401, CAC406, CAC407, CAC408 muaj lub siab zoo thiab hnav tsis kam thiab tau siv dav hauv ntau qhov chaw los ntawm cov khoom siv flushing rau cov khoom siv kho tshuab.
CAC406 yog ib qho ntawm cov ntaub ntawv tseem ceeb uas muaj ntau tshaj plaws thiab muag ntim ntawm bronze-raws li tooj liab alloys.
Nws muaj kev ua haujlwm zoo thiab tau muab faib dav, tab sis nws cov khoom siv kho tshuab tsis zoo dua li CAC403 thiab nws muaj cov hmoov txhuas ntau, yog li nws siv hauv cov khoom siv flush yog txo.
CAC411 yog cov hlau lead-dawb tooj liab alloy casting siv rau ntau qhov chaw ntawm cov khoom siv dej thiab cov kav dej.
Cov yam ntxwv thiab siv cov piv txwv ntawm bronze castings
CAC401 (qib qub BC1) Bronze muaj cov hmoov lead. Zoo fluidity thiab machinability. Feem ntau siv nyob rau hauv li qub, dej txhaj tshuab, bearings, nameplates, mechanical qhov chaw, thiab lwm yam.
CAC402 (qib qub BC2) muaj qhov thib ob siab tshaj corrosion kuj tom qab CAC403, thiab muaj lub siab ua haujlwm zoo, hnav tsis kam, thiab cov khoom siv kho tshuab. Feem ntau siv hauv bushings, tes tsho, bearings, twj tso kua mis, impellers, li qub, iav, nkoj portholes, mechanical qhov chaw, thiab lwm yam.
CAC403 (lub npe qub BC3) yog qhov ua tau zoo tshaj plaws rau cov dej hiav txwv ntawm cov bronzes, thiab muaj lub siab zoo me ntsis, hnav tsis kam, thiab corrosion tsis kam tshaj CAC402, thiab muaj cov khoom siv zoo. Nws yog tsuas yog siv rau hauv bushings, tes tsho, bearings, khoom siv dej, impellers, twj tso kua mis lub cev, li qub, mechanical qhov chaw, thiab lwm yam.
CAC406 (lub npe qub BC6) Leaded bronze muaj cov zis loj thiab yog qhov yooj yim kom tau txais. Zoo siab tsis kam, hnav tsis kam, castability, thiab machinability. Nws yog tsuas yog siv rau hauv cov khoom siv dej, bearings, twj tso kua mis, li qub, mechanical qhov chaw, thiab lwm yam.
CAC407 ( qub hom BC7) Bronze muaj cov hmoov lead. Cov khoom siv kho tshuab me ntsis zoo dua li CAC406, nrog kev ua haujlwm siab, hnav tsis kam, castability, thiab machinability. Nws yog tsuas yog siv rau hauv cov khoom siv dej, bearings, twj tso kua mis, li qub, mechanical qhov chaw, thiab lwm yam.
CAC408 Nws yog bronze nrog cov ntsiab lus tsis tshua muaj hlau lead, nrog cov ntsiab lus txhuas qis dua CAC406, tab sis cov khoom siv kho tshuab thiab corrosion kuj zoo ib yam li CAC406, tab sis lub tshuab ua haujlwm tsis zoo. Feem ntau yog siv rau hauv cov khoom siv dej, bearings, twj tso kua mis, li qub, mechanical qhov chaw, thiab lwm yam.
CAC411 Ib hom tshiab ntawm cov hlau lead-dawb tooj liab alloy casting uas ua tau raws li cov txheej txheem kho cov hmoov lead dissolution hauv kais dej. Lub elongation tensile lub zog yog sib npaug rau CAC406, tab sis lub machinability tsis zoo. Feem ntau siv hauv cov khoom siv dej, cov khoom siv kho tshuab, thiab lwm yam.
