Nws kuj yog ib qho yooj yim rau txheej txheem thiab tuaj yeem molded, machined, thiab tsim siv ntau yam txuj ci, xws li casting, extrusion, thiab forging, ua rau nws muaj ntau yam khoom siv rau ntau yam haujlwm. Vim tias nws cov thermal conductivity siab, C28000 tooj dag tuaj yeem siv los ua cov khoom siv xws li cov khoom siv hluav taws xob thiab cov tshuab hluav taws xob. Nws kuj yog ib qho kev coj ncaj ncees, ua rau nws yog ib qho khoom siv tooj liab nrov hauv cov khoom siv hluav taws xob thiab hluav taws xob.
UNS C28000 tooj dag muaj oxidation zoo dua. Nws tiv taus xeb thiab lwm yam corrosion, tshwj xeeb tshaj yog thaum raug cua thiab ya raws. Txawm li cas los xij, zoo li feem ntau tooj liab alloys, nws tarnishes nrog lub sij hawm vim oxygen thiab lwm yam atmospheric paug. Nws yog ib qho tseem ceeb kom ua kom lub ntsej muag ntawm UNS C28000 tooj dag huv si thiab tsis muaj kuab paug txhawm rau khaws nws cov oxidation tsis kam.

Machinability ntawm UNS C28000 Brass
Vim tias UNS C28000 tooj dag yog machinable, nws tuaj yeem txiav tau yooj yim, drilled, thiab zoo li tus lej ntawm cov cuab yeej txiav thiab cov txheej txheem. Nws kuj tseem hloov tau yooj yim, uas txhais tau hais tias nws tuaj yeem khoov tau yooj yim, twisted, thiab ncab yam tsis muaj tawg lossis tawg.
Weldability ntawm UNS C28000 Brass
UNS C28000 tooj dag yog yooj yim welded siv ntau yam vuam txheej txheem xws li roj tungsten arc vuam (GTAW), roj hlau arc vuam (GMAW), thiab kuj welding.
Corrosion Resistance ntawm UNS C28000 Brass
Rau kev siv nyob rau hauv cov dej hiav txwv hnyav tsawg, UNS C28000 tooj dag muaj zog atmospheric corrosion kuj nrog rau cov dej tsis zoo corrosion kuj. Txawm li cas los xij, vim tias nws yooj yim rau dezincification, UNS C28000 tooj dag tsis pom zoo siv rau hauv dej hiav txwv lossis lwm yam mob hnyav heev.
