UNS C33000 yog ib hom tooj dag alloy khoom plig rau nws ntau siv nyob rau hauv ntau yam lag luam. Cov khoom siv ruaj khov thiab xeb-resistant no muaj ntau daim ntawv thov kev lag luam, nrog rau cov khoom siv rau kev tsim kho xws li lub qhov rais thav duab, qhov rooj qhov rooj thiab cov kab hlau rhuav. Nws kuj tseem tuaj yeem siv los tsim cov khoom siv rau qee yam ntawm cov cav tsheb thiab cov roj siv hluav taws xob, nrog rau cov kav dej thiab cov khoom siv dej. Brass 330 feem ntau pom muaj nyob rau hauv cov twj paj nruag xws li trumpets, flutes thiab trombones vim nws cov hluav taws xob conductivity. Tag nrho cov kev ua tau zoo no ua rau Brass 330 yog ib qho khoom muaj nqis rau cov neeg ua haujlwm hauv ntau qhov chaw sib txawv uas xav tau cov ntaub ntawv muaj txiaj ntsig kom tau txais txoj haujlwm tiav.
Brass 330 yog qhov yooj yim rau vuam nrog cov cuab yeej siv thiab cov txheej txheem, ua rau nws zoo tagnrho rau kev siv qhov twg vuam yog qhov tsim nyog. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub vuam sib txuas yuav tsum tau npaj kom zoo ua ntej vuam kom ntseeg tau tias muaj zog tshaj plaws tom qab vuam. Qhov no suav nrog kev ntxuav cov hlau nto nrog txhuam txhuam los yog lwm yam khoom siv abrasive thiab tom qab ntawd preheating cov hlau ua ntej vuam pib.
Thaum nws los txog rau tuav tiv thaiv corrosion, Brass 330 yog ib qho kev xaiv txhim khu kev qha. Hom tooj dag no muaj kev ua tau zoo thoob plaws hauv qhov chaw corrosive vim nws cov ntsiab lus zinc.
