Brass Line: Cov yam ntxwv tseem ceeb, kev siv, thiab qhov zoo ntawm cov khoom siv tooj dag

Taw qhia
Cov khoom siv tooj dag, feem ntau yog ua los ntawm cov hlau alloy ntawm tooj liab thiab zinc, paub txog lawv lub zog, kev tiv thaiv corrosion, thiab kev zoo nkauj. Siv nyob rau hauv ntau yam kev lag luam, tooj dag kab muab ob qho tib si kev ua haujlwm thiab cov txiaj ntsig zoo nkauj. Kab lus no qhia txog cov yam ntxwv tseem ceeb, kev siv, thiab qhov zoo ntawm cov khoom siv tooj dag, qhia txog lawv cov kev siv ntau yam thiab qhov tseem ceeb hauv kev tsim khoom niaj hnub.
Cov yam ntxwv tseem ceeb
Cov khoom siv tooj dag yog tsim los ntawm kev sib xyaw tooj liab thiab zinc hauv qhov sib txawv, tso cai rau cov tuam txhab tsim cov khoom siv tooj dag nrog ntau yam khoom sib txawv. Cov hlau feem ntau muaj 60-90% tooj liab, nrog rau qhov seem ua los ntawm zinc. Qhov tshwm sim yog cov hlau uas muaj zog dua cov tooj liab ntshiab thaum tseem tswj tau zoo heev malleability, ua kom yooj yim rau hauv cov ntawv nyias, cov xov hlau, lossis cov kav dej. Brass kuj tseem tiv taus corrosion, ua rau nws zoo tagnrho rau siv nyob rau hauv ib puag ncig uas raug dej los yog tshuaj lom neeg. Tsis tas li ntawd, tooj dag muaj cov xim zoo nkauj daj-golden, uas ua rau nws txawv, polished tsos uas feem ntau siv rau hauv cov khoom siv kho kom zoo nkauj thiab ornamental.
Kev siv thiab kev siv
Cov khoom siv tooj dag yog siv nyob rau hauv ntau yam kev lag luam, los ntawm cov kav dej mus rau cov tshuab hluav taws xob mus rau kev kho kom zoo nkauj. Hauv cov kav dej, cov kab tooj dag feem ntau yog siv rau cov kav dej, faucets, thiab fittings vim lawv tsis kam tiv thaiv corrosion thiab muaj peev xwm tiv taus cov kev mob siab. tooj dag kuj yog ib qho khoom siv nrov hauv kev lag luam hluav taws xob rau cov khoom sib txuas, cov keyboards, thiab cov terminals, vim nws yog ib qho khoom siv hluav taws xob zoo heev thiab tiv thaiv oxidation. Tsis tas li ntawd, tooj dag lub ntsej muag zoo nkauj ua rau nws zoo tagnrho rau cov khoom siv zoo nkauj xws li cov hniav nyiaj hniav kub, cov twj paj nruag (xws li trumpets thiab saxophones), thiab khoom siv rau rooj tog thiab qhov rooj.
Hauv kev lag luam automotive thiab aerospace, tooj dag feem ntau yog siv los ua cov khoom xws li radiators, heat exchangers, thiab engine parts, benefiting from its strength and resistance to heat. Cov khoom siv tooj dag kuj muaj nyob rau hauv ib puag ncig marine, qhov chaw uas lawv siv rau cov khoom xws li nkoj fittings thiab propellers, vim cov hlau tuaj yeem tiv taus seawater corrosion.
Cov txiaj ntsig
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov khoom siv tooj dag yog lawv cov kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ntub dej lossis tshuaj lom neeg ua phem. Qhov no ua rau lawv zoo tagnrho rau kev siv mus sij hawm ntev nrog kev saib xyuas tsawg. Brass kuj tseem muaj zog heev, muab qhov sib npaug zoo ntawm lub zog thiab yoog raws, uas ua rau nws haum rau ntau yam kev siv tshuab thiab cov qauv siv. Cov hlau muaj peev xwm ua tau yooj yim machined, tsim, thiab cam khwb cia ua rau nws muaj ntau yam thiab tsim nyog rau kev tsim cov duab meej, nyuaj. Tsis tas li ntawd, cov khoom siv tooj dag muaj cov thermal conductivity zoo heev, ua rau lawv zoo tagnrho rau kev siv hluav taws xob hloov pauv xws li radiators thiab heat exchangers.
Lwm qhov txiaj ntsig tseem ceeb yog tooj dag tus nqi zoo nkauj. Nws cov xim zoo nkauj golden thiab du ua rau nws yog qhov kev xaiv nrov rau cov khoom zoo nkauj, cov hniav nyiaj hniav kub, thiab cov khoom siv high-end, ntxiv ob qho tib si kev ua haujlwm thiab kev zoo nkauj rau cov khoom kawg.
Xaus
Hauv kev xaus, cov khoom siv tooj dag muaj kev sib xyaw ua ke ntawm kev ua haujlwm ntev, kev tiv thaiv corrosion, thiab kev zoo nkauj zoo nkauj uas ua rau lawv tseem ceeb hauv ntau qhov kev lag luam. Los ntawm cov kav dej thiab hluav taws xob rau cov khoom siv kho kom zoo nkauj thiab kev siv tshuab ua haujlwm siab, cov kab tooj dag muab cov kev daws teeb meem ruaj khov, ntev ntev. Nrog lawv cov khoom siv ntau yam thiab ntau yam kev siv, cov khoom siv tooj dag txuas ntxiv yog cov khoom siv tseem ceeb hauv ob qho tib si kev ua haujlwm thiab khoom siv hauv kev tsim khoom niaj hnub thiab tsim.
