Cov ntsiab lus tseem ceeb muaj nyob hauvUNS C22000yog tooj liab (Cu), lead (Pb), zinc (Zn), thiab tin (Sn). Cov tshuaj muaj pes tsawg leeg ntawm cov hlau no suav nrog 67% tooj liab, 28% zinc, 5% txhuas, 0.25% tin, thiab lwm yam khoom xws li hlau (Fe), manganese (Mn), nickel (Ni), sulfur (S) thiab phosphorus (P). Cov ntsiab lus no ua ke los tsim cov hlau nplaum uas tiv taus corrosion los ntawm feem ntau cov kua qaub thiab alkalis ntawm chav tsev kub.

Bronze 220Nws muaj qhov kub thiab txias ntawm 930 degree (1706 degree F) thiab qhov ceev ntawm 8.8 g / cm3. Nws raug cais raws li alpha-beta tooj dag vim nws muaj ob qho tib si alpha ( ) thiab beta ( ) theem hauv nws cov microstructure. Lub hardness ntau ntawm 70 txog 95 Brinell (HBW), nrog lub zog tensile ntawm 600 MPa (87 ksi). Nws pom zoo hnav tsis kam ua tsaug rau nws cov ntsiab lus txhuas siab, ua rau nws cov khoom zoo tagnrho rau bearings thiab bushings.
Mechanical Properties ntawm220 Nyiajsuav nrog qib siab ntawm lub zog vim nws cov hlau sib xyaw ua ke, uas pab ua kom cov khoom siv ductility. Nws kuj muaj cov thermal stability zoo heev, ua rau nws tsim nyog rau kev siv kub xws li roj turbines lossis boilers qhov kub tuaj yeem ncav cuag 450 degree (842 degree F). Tsis tas li ntawd, cov khoom no muaj kev ua haujlwm zoo, ua kom yooj yim shaping thaum lub sij hawm tsim khoom xws li forging lossis casting.

Bronze C220muaj ntau daim ntawv thov vim nws lub cev muaj zog, xws li kev tiv thaiv corrosion los ntawm feem ntau cov kua qaub thiab alkalis thiab thermal stability zoo, tso cai rau nws siv rau hauv cov ntawv thov kub xws li roj turbines lossis boilers yam tsis muaj kev cuam tshuam nws qhov zoo lossis kev ncaj ncees lub sijhawm. Feem ntau siv muaj xws li valve stems, xauv lub cev, piston rings, bearings, bushings, thiab hluav taws xob fittings. Txhawm rau kom muaj kev tiv thaiv corrosion siab tshaj plaws thaum siv Bronze 220, nws yuav tsum tau kho cua sov ua ntej daim ntawv thov kom ua kom muaj txiaj ntsig zoo ntawm cov hlau alloy cov tshuaj muaj pes tsawg leeg, suav nrog nce hardness thiab txhim kho tensile zog.
220 Nyiajmachining tsim cov khoom siv tooj liab los ntawm kev txiav, drilling, sib tsoo thiab lwm yam haujlwm. Hom machining no yuav tsum tau nkag siab txog cov khoom siv hlau kom siv cov cuab yeej thiab cov tswv yim tsim nyog los tsim cov duab thiab cov qauv tsim.C22000xav tau kev npaj kom meej, qhov tseeb hauv kev ntsuas, thiab kev txawj ntse uas pab tsim cov khoom zoo nkauj nrog lub zog zoo. Nrog rau qhov kev paub no, machinists tuaj yeem tsim cov khoom zoo yam tsis muaj kev txiav txim siab los yog ceev thaum khaws cov nqi tsim khoom qis.
220 Nyiajyog ib qho txhuas bronze alloy paub txog nws cov weldability thiab zoo heev tiv thaiv corrosion. Cov hlau yog tsim los ntawm tooj liab, txhuas, thiab hlau nrog cov kab ntau ntawm manganese, npib tsib xee, thiab silicon.Alloy 220Nws muaj qhov kub thiab txias tsis tshua muaj qhov tso cai rau nws tuaj yeem yooj yim koom nrog cov txheej txheem vuam xws li roj hlau arc vuam (GMAW). Bronze 220 muab lub zog siab txawm tias nyob rau hauv ib puag ncig hnyav vim nws qhov siab corrosion kuj. Cov txheej txheem kho cua sov zoo li quenching lossis tempering tuaj yeem txhim kho nws lub zog ntxiv. Bronze 220 yog qhov zoo tagnrho rau cov haujlwm uas xav tau cov ntaub ntawv muaj zog weldable hauv kev siv corrosive.
