1. Chemical Composition (Core Distinction)
Bronze
Base Hlau: Copper (Cu) yog cov khoom tseem ceeb (feem ntau 80–95%).
Ntsiab Alloying Element: Tin (Sn) yog ib txwm muaj thiab txhais tau hais tias additive (5-20%).
Lwm yam Additives(rau customization):
Phosphorus (P): Txhim kho lub zog thiab corrosion kuj (xws li phosphor bronze).
Aluminium (Al): Txhim kho hnav tsis kam thiab siab -kub stability (xws li, txhuas bronze).
Lead (Pb): Ua kom muaj peev xwm ua tau zoo (piv txwv li, leaded bronze).
Zinc (Zn): Tej zaum yuav raug ntxiv me me los txo tus nqi, tab sis tin tseem yog cov khoom tseem ceeb alloying.
tooj dag
Base Hlau: Copper (Cu) yog cov khoom tseem ceeb (feem ntau 60–90%).
Ntsiab Alloying Element: Zinc (Zn) yog lub ntsiab additive (10–40%).
Lwm yam Additives(rau kev ua haujlwm tuning):
Lead (Pb): Txhim kho machinability thiab txo kev sib txhuam (xws li, dawb- txiav tooj dag).
Tin (Sn): Txhim kho corrosion kuj (tshwj xeeb tshaj yog nyob rau hauv marine ib puag ncig, piv txwv li, naval tooj dag).
Nickel (Ni): Boosts zog thiab ductility (xws li, npib tsib xee tooj dag).
Aluminium (Al): Txhim kho oxidation tsis kam ntawm qhov kub thiab txias.
2. Lub cev & Mechanical Properties
3. Kev tsim khoom & kev ua haujlwm
Bronze
Casting: Txoj kev nyiam (piv txwv li, xuab zeb casting, peev casting) vim nws zoo heev fluidity; siv rau cov khoom loj (piv txwv li, li qub, lub zog, cov duab).
Wrought processing: Txwv tsis pub (vim qis ductility); Kev ua haujlwm kub yog ntau dua li kev ua haujlwm txias.
Tshuab dhos: Yuav tsum tau siv cov cuab yeej nyuaj thiab qeeb qeeb; leaded bronze yog siv rau qhov xav tau precision machining.
tooj dag
Wrought processingCov txheej txheem tseem ceeb (kev ua haujlwm txias: kos duab, extrusion, stamping; kub ua haujlwm: forging, dov); siv rau cov kav dej, cov raj, cov ntawv, thiab cov xov hlau.
Casting: Siv rau cov duab nyuaj (piv txwv li, faucets, fittings) tab sis tsawg dua rau cov tooj liab.
Tshuab dhos: Highly machinable (cov tooj dag txhuas yog dav siv rau cov ntsia hlau, ceev, thiab cov khoom siv precision).
Koom nrog: Yooj yim rau solder, braze, thiab weld (zoo dua li tooj liab rau kev sib dhos).
4. Daim ntawv thov (Kev lag luam-Kev siv tshwj xeeb)
Bronze
Muaj Machinery: Bearings, bushings, gears, thiab hnav daim hlau (zoo hnav tsis kam).
Marine Engineering: Propellers, nkoj hull fittings, thiab seawater li qub (superior corrosion kuj nyob rau hauv dej ntsev).
Architecture & Art: Pej thuam, sculptures, hniav plaques, thiab keeb kwm monuments (patina tsim ntxiv aesthetic tus nqi).
Hluav taws xob & Electronics: Springs, connectors, thiab terminals (phosphor bronze muaj zoo hluav taws xob conductivity thiab qaug zog kuj).
Aerospace: High-cov khoom kub (aluminium bronze resists oxidation ntawm qhov kub siab).
tooj dag
Cov kav dej & Piping: Cov kav dej, fittings, faucets, thiab li qub (yooj yim tsim, corrosion-tiv taus hauv dej haus).
Kho vajtse & Fasteners: Screws, ceev, bolts, thiab hinges (zoo machinability thiab ductility).
Hluav taws xob Cheebtsam: Cov khoom siv hluav taws xob, cov khoom sib txuas, thiab cov terminals (zoo hluav taws xob conductivity; pheej yig dua tooj liab).
Suab paj nruag: Trumpets, trombones, thiab tubas (acoustic zog thiab golden tsos).
Automotive: Radiator cores, nres kab, thiab cov hniav zoo nkauj (formability thiab corrosion kuj nyob rau hauv ib puag ncig me me).
Cov khoom siv: Cov xauv, cov yuam sij, zippers, thiab cov khoom siv kho kom zoo nkauj (zoo nkauj thiab ua haujlwm tau zoo).
5. Nqi & Muaj
Bronze: Feem ntau kim dua tooj dag. Tin yog cov hlau tsis tshua muaj thiab kim tshaj li zinc, ua rau cov nqi tsim khoom.
tooj dag: Tus nqi ntau dua - zoo. Zinc muaj ntau thiab pheej yig, ua rau tooj dag yog qhov kev xaiv nrov rau siab - ntim, nqi- cov ntawv thov nkag siab.
Muaj: Ob leeg muaj dav, tab sis bronze alloys (piv txwv li, aluminium bronze, phosphor bronze) yuav muaj sij hawm ntev dua rau cov qauv kev cai.
