Qhov sib txawv tseem ceeb ntawm tooj dag thiab tooj liab yog tooj dag muaj tooj liab thiab zinc thaum tooj liab muaj tooj liab thiab tin.
Ob qho tib si tooj dag thiab tooj liab yog cov hlau ntawm tooj liab. Lawv yog cov kev daws teeb meem ntawm tooj liab thiab lwm yam alloying ntsiab. Yeej, peb tuaj yeem faib cov tooj dag thiab tooj liab nyob ntawm lub ntsiab alloying. Qhov kev sib txawv no ua rau cov khoom sib txawv ntawm ob lub alloys.
Brass yog dab tsi?
Brass yog tooj liab-zinc alloy; nws cov ntsiab lus zinc yog txog li ntawm 45% ntawm qhov hnyav. Feem ntau, manufacturers ntxiv tin, aluminium, silicon, manganese, npib tsib xee thiab ua rau tooj dag ua ntxiv alloying ntsiab. Ntxiv mus, peb tuaj yeem tau txais cov khoom zoo ntawm tooj dag los ntawm kev sib txawv ntawm cov feem pua ntawm cov khoom xyaw.
Vim nws qhov zoo tshaj plaws castability thiab tus nqi qis, tooj dag yog cov tooj liab ntau tshaj plaws. Zinc hauv tooj dag ua rau nws muaj zog thiab pheej yig dua tab sis txo cov hluav taws xob conductivity thiab tiv taus corrosion. Tsis tas li ntawd, hloov cov zinc feem pua muab qhov kev hloov pauv ntawm cov xim hauv tooj dag. Vim nws cov xim daj / kub ntawm tooj dag, lawv muaj txiaj ntsig zoo rau kev kho kom zoo nkauj. Malleability yog ib qho ntawm cov khoom tseem ceeb ntawm tooj dag. Vim li no, tooj dag tuaj yeem thinned tawm mus rau cov ntawv zoo heev. Malleability nyob ntawm cov ntsiab lus zinc ntawm tooj dag. Brass nrog cov ntsiab lus siab zinc yog tsawg malleable. Tsis tas li ntawd, cov coefficient ntawm kev sib txhuam ntawm tooj dag yog tsawg. Cov cuab yeej no ua rau tooj dag haum rau cov ntawv thov kev sib txhuam tsawg.
Bronze yog dab tsi?
Feem ntau, bronze yog tooj liab-tin alloy. Ntxiv mus, tooj liab-aluminium alloys thiab tooj liab silicon alloys kuj hu ua bronze. Peb tuaj yeem faib cov bronze nyob ntawm lwm cov khoom siv alloying. Lead, zinc, phosphorous, aluminium, silicon, thiab nyiaj yog nws cov ntsiab lus alloying ntxiv.
Bronze kim dua tooj dag vim qhov tseem ceeb alloying caij hauv bronze yog tin. Tin tsub kom lub zog, hardness, fluidity thiab corrosion kuj ntawm bronze. Yog li ntawd, bronze yog me ntsis superior rau tooj dag. Bronze yog me ntsis malleable dua tooj dag vim muaj cov tin.
Dab tsi yog qhov zoo sib xws ntawm Brass thiab Bronze?
- Ob qho tib si tooj dag thiab tooj liab yog tooj liab.
- Cov alloys no yog ductile, ua haujlwm tau thiab muaj hluav taws xob zoo heev.
- Vim lawv muaj kev tiv thaiv corrosion thiab zoo thermal conductivity, lawv yog siv nyob rau hauv lub tshav kub exchangers, cua sov systems, tsheb daim ntawv thov, kav dej thiab fittings.
- Cov ntsiab lus ntxiv alloyed nrog tooj liab txo qhov melting point ntawm lub hauv paus hlau, muab cov alloys zoo castability.
- Seawater condenser systems, yeeb nkab ua haujlwm hauv cov nroj tsuag tshuaj, khoom siv hauv tsheb, kev siv dej hiav txwv, npib, khoom plig, thermocouples, tsis kam xaim, thiab lwm yam yog qee qhov kev siv tooj dag thiab tooj liab.
Qhov txawv ntawm Brass thiab Bronze yog dab tsi?
Qhov sib txawv tseem ceeb ntawm tooj dag thiab tooj liab yog tooj dag muaj tooj liab thiab zinc thaum tooj liab muaj tooj liab thiab tin. tooj dag muaj zinc ua lub ntsiab alloying, thaum tin los yog txhuas los yog silicon yog lub ntsiab alloying ntsiab ntawm bronze. Yog li ntawd, tooj dag yog pheej yig dua bronze. Tsis tas li ntawd, tooj dag yog ntau malleable tshaj bronze. Cov nram qab no infographic qhia txog qhov sib txawv ntawm tooj dag thiab tooj dag.
Summary – Brass vs Bronze
Ob qho tib si tooj dag thiab tooj liab yog cov hlau ntawm tooj liab. Qhov sib txawv tseem ceeb ntawm tooj dag thiab tooj liab yog tooj dag muaj tooj liab thiab zinc thaum tooj liab muaj tooj liab thiab tin.
