Aluminium Bronze vs Brass -Corrosion-Resistant

Puas yog Aluminium Bronze Ntau Corrosion-Resistant dua tooj dag? Puas tsim nyog rau Marine lossis Humid Ib puag ncig?

1. Corrosion Resistance piv

Yog lawm,txhuas bronze(xws li, C60600, C61300, C63000) feem ntau pom zoo corrosion kuj piv rautooj dag(piv txwv li, C26000, C27000, C28000), tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav. Cov laj thawj tseem ceeb yog:

Aluminium Oxide Zaj duab xis: Aluminium nyob rau hauv lub alloy tsim ib tug ntom, adherent Al₂O₃ passive zaj duab xis nyob rau saum npoo, uas ua raws li ib tug barrier tiv thaiv oxygen, noo noo, thiab corrosive media (xws li dej ntsev, acids). Cov yeeb yaj kiab no tus kheej - kho yog khawb, tuav ntev - tiv thaiv lub sijhawm.

Kev txwv tooj dag: Brass feem ntau muaj tooj liab thiab zinc. Zinc yog nquagdezincification(xaiv corrosion qhov twg zinc yog leached tawm, tawm hauv ib tug ntxeem tau tooj liab qauv) nyob rau hauv ntub, qab ntsev, los yog acidic ib puag ncig. Qhov no ua rau cov khoom tsis muaj zog thiab txo nws txoj kev ua haujlwm.

Nyob rau hauv tej yam kev mob corrosive (xws li, dej ntsev, muaj av noo, tshuaj vapors), txhuas bronze outperforms tooj dag los ntawm resisting pitting, crevice corrosion, thiab degradation.

2. Tsim nyog rau Marine / Humid Ib puag ncig

Aluminium bronze yog qhov tsim nyog rau thaj chaw marine thiab ntub dej, ua rau nws nyiam cov khoom siv hauv cov ntawv thov no:

Kev lag luam marine: Siv rau cov kiv cua, li qub, twj tso kua mis, nkoj hull fittings, thiab offshore platform Cheebtsam. Nws tiv taus cov dej ntsev corrosion (xws li dej hiav txwv immersion thiab thaj chaw txaws) tiv thaiv kev puas tsuaj txawm tias nyob rau lub sijhawm ntev - raug.

Humid/Coastal Environments: Zoo tagnrho rau architectural hardware (piv txwv li, handrails, fasteners), muaj cov cuab yeej siv hauv cov chaw ua haujlwm ntub dej, thiab cov chaw ua haujlwm hauv ntug dej hiav txwv. Nws tiv taus cov av noo siab, tshuaj tsuag ntsev, thiab kub hloov pauv yam tsis muaj xeb lossis poob txhua yam khoom.

Los ntawm qhov sib piv, tooj dag tsis pom zoo rau kev siv ntev hauv cov dej hiav txwv / av ntub vim dezincification thiab txo cov kav ntev. Rau cov ntawv thov tseem ceeb uas xav tau kev tiv thaiv corrosion hauv cov xwm txheej zoo li no, aluminium bronze yog qhov kev xaiv zoo dua.

Cov ntsiab lus

Aluminium bronze muaj kev tiv thaiv corrosion zoo dua li tooj dag, feem ntau vim nws cov yeeb yaj kiab tiv thaiv aluminium oxide. Nws yog qhov zoo - haum rau thaj chaw marine thiab ntub dej, muab kev ua haujlwm ntev - lub sijhawm ua haujlwm thiab ua haujlwm ntev, thaum tooj dag tsis zoo rau cov xwm txheej hnyav no.
