Yuav ua li cas bronze cais nyob rau hauv North America?
Bronze yog cov hlau alloy uas feem ntau yog tooj liab, txog 12% txog 12.5% tin, thiab lwm yam hlau xws li txhuas, manganese, zinc, lossis npib tsib xee. Qee zaum nws muaj cov nonmetals lossis metalloids xws li arsenic, phosphorus, thiab silicon. Txawv hlau thiab nonmetallic add-ons tsim ntau yam ntawm bronze alloys nrog ntau yam zoo.
Bronze feem ntau yog ib qho zoo heev alloy. Nws feem ntau tsuas yog oxidize rau ntawm qhov chaw, thiab thaum lub tooj liab oxide txheej yog tsim, cov hlau tseem ceeb yog tiv thaiv los ntawm corrosion ntxiv. Cov txheej txheem no tuaj yeem pom ntawm cov mlom qub. Copper-based alloys xws li tooj liab muaj qhov qis qis dua li cov hlau los yog hlau, uas ua rau lawv yooj yim los tsim. Bronze yog kwv yees li 10% denser dua hlau, txawm hais tias alloys siv txhuas lossis silicon yuav muaj qhov ntom me ntsis. Bronze muaj thermal conductivity thiab hluav taws xob zoo dua li cov hlau feem ntau. Nws feem ntau kim dua li cov hlau tab sis pheej yig dua li cov nickel-based alloys. Nws yog ib tug dull xim nrog ib tug faint nplhaib rau ntawm qhov chaw.
Kab lus no saib ntawm ntau hom tooj liab, tshwj xeeb sib txawv alloys, lawv cov kev siv, thiab cov khoom.
Tin Bronze
Bronze nrog tin ua lub ntsiab alloying. Cov ntsiab lus tin feem ntau yog nyob nruab nrab ntawm 3 thiab 14%, thiab nws yog siv los ua cov khoom elastic thiab hnav-tiv taus qhov chaw. Deformed tin bronze muaj tsis ntau tshaj 8% tin, thiab qee zaum phosphorus, txhuas, zinc thiab lwm yam ntxiv. Phosphorus yog ib qho zoo deoxidizer thiab tuaj yeem txhim kho fluidity thiab hnav tsis kam. Cov txhuas yog ntxiv rau tin bronze los txhim kho machinability thiab hnav tsis kam, thiab zinc yog ntxiv los txhim kho cov khoom casting. Cov hlau no muaj cov khoom siv zoo heev, cov khoom siv los tiv thaiv kev sib txhuam thiab corrosion kuj, yog ib qho yooj yim los txiav, muaj zoo brazing thiab vuam zog, muaj ib tug me me shrinkage coefficient thiab tsis-sib nqus. Coatings xws li tooj dag bushings, lub tes tsho, thiab cov khoom tiv thaiv hlau nplaum tuaj yeem npaj tau los ntawm cov nplaim hluav taws xob txau thiab arc txau.
Silicon Bronze
Silicon bronze, qee zaum hu ua liab silicon bronze, muaj tooj liab, silicon thiab zinc. Nws feem ntau muaj txog li 6% silicon. Nws tuaj yeem tsim los ntawm tooj liab, silicon thiab lwm yam alloys xws li manganese, tin, hlau thiab zinc. Nws yog lub zog muaj zog alloy nrog yooj yim pouring peev xwm, siab corrosion kuj thiab ib tug txaus nyiam nto tiav. Nws yog feem ntau siv rau lub twj tso kua mis thiab lub valve.
Phosphor Bronze
Phosphor bronze, tseem hu ua tin bronze, muaj tooj liab, txog li 11% tin, thiab txog li 0.35% phosphorus. Qhov sib ntxiv ntawm phosphorus nce qhov hnav tsis kam thiab nruj ntawm bronze. Cov alloy paub txog nws qhov toughness, durability, tsis tshua muaj coefficient ntawm kev sib txhuam, thiab nplua nplej loj. Phosphor bronze feem ntau yog siv los ua cov khoom siv tiv thaiv corrosion, cov khoom siv hluav taws xob, cov tshuab ntxhua khaub ncaws, cov tshuab nqus dej, cov tshuab raj, thiab cov twj paj nruag.
Aluminium Bronze
Aluminium bronze muaj tooj liab, li 6% mus rau 12% txhuas, thiab qee zaum lwm yam ntxiv xws li hlau, npib tsib xee, manganese, thiab silicon. Nws yog lub zog siab, corrosion-resistant, thiab tarnish-resistant alloy. Cov kev siv feem ntau yog marine hardware thiab twj tso kua mis uas thauj corrosive kua vim nws corrosion kuj, tshwj xeeb tshaj yog rau seawater. Nws kuj tseem siv rau hauv kev lag luam roj av, petrochemical, thiab dej kev lag luam.
Manganese tooj liab
Manganese bronze yog tsim los ntawm 3% manganese, tooj liab, zinc, txhuas, thiab hlau. Nws yog shock-resistant thiab deforms es tsis so. Nws yog heev resistant rau dej ntsev corrosion, yog li nws yog feem ntau siv nyob rau hauv marine propellers. Manganese bronze kuj tseem siv rau valve thiab twj tso kua mis, lub zog, ceev thiab bolts.
Cov kabmob Bronze
Raws li lub npe implies, bearing bronze feem ntau yog siv los ua bearings thiab bushings. Cov kabmob bronze muaj cov ntsiab lus txhuas ntawm 6% mus rau 8%. Cov ntsiab lus txhuas siab dua muab nws cov khoom sib txhuam qis, ua rau nws tsim nyog rau qhov chaw hnav khaub ncaws siab, tshwj xeeb tshaj yog cov chaw uas nyuaj rau kev nkag los yog tswj.
Tooj-Nickel
Copper-nickel bronze, tseem hu ua dawb tooj liab, muaj ntau dua ntawm nickel, los ntawm 2% mus rau 30%. Zoo ib yam li lwm hom bronze alloys, nws yog ruaj thiab tiv taus corrosion, tshwj xeeb tshaj yog rau cov dej ntsev. Nws kuj muaj siab thermal stability. Copper-nickel bronze yog siv rau hauv cov khoom siv hluav taws xob, cov khoom siv hauv hiav txwv, hulls, twj thiab li qub.
Bismuth Bronze
Bismuth tooj liab muaj 1% mus rau 6% bismuth. Nws yog heev corrosion-resistant, ntau ductile thiab thermally conductive. Nws polishes zoo, yog li nws yog qee zaum siv nyob rau hauv lub teeb reflectors thiab iav. Kev siv ntau tshaj plaws hauv kev lag luam yog hauv bearings. Bismuth bronze kuj tau siv los ua cov khoom siv hauv chav ua noj thoob plaws hauv keeb kwm. Nws yog tam sim no qee zaum siv los hloov cov hlau lead.
