642 Bronze Chemical Properties
Raws li cov tooj liab-raws li alloy, C64200 muaj kev tiv thaiv corrosion zoo heev thaum raug dej los yog dej ntsev ib puag ncig. Nws cov ntsiab lus tooj liab siab kuj ua rau nws tiv taus hnav thiab tsim kua muag los ntawm cov khoom hnav hauv nws ib puag ncig.
642 Bronze Mechanical Properties
Nrog nws lub zog tensile siab thiab qis thermal expansion tus nqi, Bronze 642 tuaj yeem tuav tau hauv cov khoom hnyav dhau lub sijhawm ntev yam tsis muaj deforming lossis tawg. Nws kuj muaj zog qaug zog zoo, ua rau nws tsim nyog siv rau hauv cov ntawv thov uas muaj kev vibration siab lossis poob siab loading qib.

Bronze 642 siv
Vim nws zoo heev hnav thiab corrosion kuj yam ntxwv, siab tensile zog, thiab qaug zog kuj zog,Hlau C64200feem ntau yog siv rau hauv daim ntawv thov xws li bearings thiab bushings qhov twg cov khoom no muaj txiaj ntsig zoo. Nws kuj tseem tuaj yeem siv rau hauv kev siv dej hiav txwv vim nws qhov kev tiv thaiv corrosion thaum raug rau cov dej ntsev ib puag ncig thiab nws muaj peev xwm tiv taus qhov kub thiab txias uas tau ntsib hauv cov tshuab ua haujlwm ntawm kev ceev ceev hauv cov xwm txheej load.
Bronze 642 yog ib qho hlau uas ua los ntawm 90% tooj liab thiab 10% tin.
Nws yog cov hlau uas muaj zog heev thiab ruaj khov uas tiv taus corrosion.
Nws yog feem ntau siv rau hauv kev tsim vaj tse thiab txuas hniav vim nws lub zog.
Nws kuj yog siv los tsim cov npib, khoom plig, thiab lwm yam khoom uas yuav tsum tau ua kom ntev.
Bronze 642 kuj tseem siv tau rau cov duab puab thiab lwm yam kev kos duab vim tias nws tuaj yeem muab pov rau hauv txhua yam duab.

Corrosion Resistance
Raws li tau hais los saum no,Hlau alloy C64200muaj kev tiv thaiv corrosion zoo heev thaum raug dej los yog dej ntsev ib puag ncig, ua rau nws tsim nyog rau kev siv dej hiav txwv uas raug cov ntsiab lus corrosive tuaj yeem tshwm sim tsis tu ncua. Ntxiv rau qhov no, nws kuj muaj qhov zoo abrasion tsis kam, uas ua rau nws zoo tagnrho rau siv nyob rau hauv qhov chaw uas tuaj rau hauv kev sib cuag nrog cov ntaub ntawv abrasive thaum lub sij hawm ua hauj lwm, xws li bearings los yog bushings uas txav mus rau lwm qhov chaw thaum lub sij hawm ua hauj lwm voj voog.
Thaum tshav kub kub Resistance
Lub melting point ntawm 875 degree (1627 degree F) ua rau Bronze 642 muaj peev xwm tiv taus qhov kub thiab txias dua li lwm cov alloys yam tsis muaj deforming lossis poob cov qauv kev ncaj ncees nyob rau lub sij hawm vim huab cua kub dhau los thaum lub sijhawm ua haujlwm ntawm kev ceev hauv kev thauj khoom. Qhov no ua rau nws zoo tagnrho rau kev siv cov tshuab ua haujlwm ntawm qhov nrawm dua nyob rau lub sijhawm ntev yam tsis tas yuav tsum tau hloov ntau zaus vim muaj cua sov ntau dhau los ntawm kev raug mob ntev ntawm qhov kub siab tshaj lub sijhawm ntev.
Kev kho cua sov
Kev kho cua sov txheej txheem xws li annealing tuaj yeem ua raukob 642txhawm rau txhim kho nws lub zog thiab hardness thaum tswj kom zoo ductility rau kev txhim kho kev ua tau zoo thaum raug hnyav loads thaum lub sij hawm ua hauj lwm cycles ntev lub sij hawm ntawm lub sij hawm tsis muaj kev ua hauj lwm ntxov tsis ua hauj lwm los ntawm qaug zog vim lub sij hawm ua hauj lwm cycles nyob rau hauv load tej yam kev mob.
Tshuab dhos
Vim nws qhov qis melting point piv nrog rau lwm yam hlau, bronze tau yooj yim yuav machined siv cov txheej txheem niaj hnub no, ua rau nws haum rau ntau fabrication txheej txheem xws li drilling, tapping, tig, milling, thiab lwm yam.
Vuam
Tsis tas li ntawd, bronze tuaj yeem yooj yim welded siv TIG MIG roj vuam cov txheej txheem nyob ntawm daim ntawv thov xav tau, tso cai ntau dua thaum tsim cov khoom siv kev cai tsis muaj tawm ntawm lub txee.
