H62 tooj dag yog dab tsi?
H62 tooj dag pas nrig yog ib qho khoom siv tooj dag raws li tooj liab-zinc alloy, nrog qhov nruab nrab tooj liab cov ntsiab lus ntawm 62% thiab zinc raws li qhov sib npaug, muaj cov kab tsis huv. Cov khoom no muaj ob qho tib si zoo txhua yam thiab machinability, zoo heev plasticity nyob rau hauv lub kub lub xeev, thiab ncaj ncees plasticity nyob rau hauv lub txias xeev. Nws muaj zoo machinability, weldability, thiab corrosion kuj, tab sis muaj kev pheej hmoo ntawm corrosion cracking. Vim nws tus nqi qis thiab siv dav, nws feem ntau yog siv los tsim cov khoom thauj-cov kabmob xws li cov pins, rivets, ntxhua khaub ncaws, txiv ntseej, cov kav dej, lub ntsuas siab ntsuas, cov ntxaij vab tshaus, thiab cov radiators.

Fabrication & Processing yam ntxwv
Kub ua haujlwm: Zoo heev.Zoo tagnrho rau kub forging, extrusion, thiab stamping (pom zoo ua hauj lwm temp: 650-750 degree).
Ua haujlwm txias: Ncaj ncees rau Zoo.Yuav tsum muaj zog ntau dua -brasses; intermediate annealing tej zaum yuav xav tau rau loj deformation.
Machineability: Zoo(Machinability rating: ~30%, qhov twg dawb-txiav tooj dag C36000=100%).
Weldability & Joining:Zoo rau brazing thiab soldering. Gas welding thiab kuj welding yog ua tau; arc vuam yog qhov nyuaj.
Kev kho cua sov:Teb rau kev ntxhov siab- nyem annealing (250-400℃). Tsis nag lossis daus-hardenable.
Corrosion Resistance
General: Zoo tiv thaiv atmospheric, dej tshiab, thiab seawater corrosion.
Kev pheej hmoo tseem ceeb: Muaj kev cuam tshuam rau dezincification nyob rau hauv qhov chaw nres lossis qeeb - tsiv dej, tshwj xeeb tshaj yog muaj cov ntsiab lus chloride siab thiab pH qis. Kuj tseem ceeb rau ammonia-induced stress corrosion cracking (SCC).
Kev Tiv Thaiv Kev Tiv Thaiv: Siv nyob rau hauv ib puag ncig tsim nyog; inhibitors lossis xaiv cov khoom (xws li, arsenic- muaj tooj dag rau dezincification tsis kam) rau cov ntawv thov tseem ceeb.
Tej kev siv
Architectural & Kho kom zoo nkauj:Qhov rooj kov, hinges, xauv, architectural facades, kho kom zoo nkauj kho vajtse.
Industrial Components:Valves, twj tso kua mis qhov chaw, iav, fasteners, tshav kub exchanger daim hlau, condenser raj.
Hluav taws xob:Hluav taws xob connectors, terminals, hloov Cheebtsam.
Cov khoom siv:Cov kav dej phwj tuaj, cov khoom siv suab paj nruag, cov ntawv teev npe, cov mos txwv.
Peb lub Hoobkas
Peb lub hauv paus tsim khoom niaj hnub no tau nruab nrog kev ua tiav puv - cov txheej txheem ntau lawm rau kev tsim cov khoom siv tooj liab thiab tooj liab alloy. Lub Hoobkas nta precision smelting, nruam nruam, siab - siab extrusion, siab - ceev dov, thiab precision txiav cov cuab yeej, xyuas kom nruj tswj txhua kauj ruam ntawm tooj liab ingot rau cov khoom tiav. Peb muaj zog R & D thiab customization muaj peev xwm, ua rau peb tsim ntau yam specifications thiab tempers ntawm tooj liab raj, daim hlau, rods, xov hlau, thiab ultra- nyias foils raws li thoob ntiaj teb cov qauv (xws li ASTM, EN, JIS) thiab cov neeg siv khoom tshwj xeeb. Peb cov khoom siv dav siv hauv ntau yam lag luam, suav nrog tub yees, hluav taws xob, hluav taws xob, tsheb thauj mus los, thiab kev tsim kho.
Copper khoom ntim
Peb nkag siab tag nrho tias kev ntim khoom ruaj ntseg yog qhov tseem ceeb rau kev xa khoom tsis zoo. Ua raws li cov yam ntxwv ntawm cov khoom sib txawv, peb ntiav cov kev lag luam ntim cov kev daws teeb meem: cov raj tooj liab thiab cov pas nrig feem ntau muaj kev ruaj ntseg nrog cov tshuaj tiv thaiv - xeb sab hauv thiab ruaj khov ntoo crates lossis hlau - lub thawv ntawv txhawm rau tiv thaiv kev cuam tshuam thiab deformation thaum caij tsheb npav; tooj liab daim hlau, strips, thiab foils yog thawj zaug them nrog zaj duab xis tiv thaiv, muab tso rau hauv ib puag ncig qhuav, qhwv nrog cov ntawv tsis muaj dej thiab noo noo- cov ntaub ntawv pov thawj, thiab thaum kawg tau ntim rau hauv cov khoom siv plywood lossis steel coil thawv kom tiv thaiv cov dej noo thiab kev puas tsuaj; cov xov hlau yog zoo huv si rau ntawm ntoo los yog steel reels thiab khov kho. Tag nrho cov ntim tau sau meej meej thiab ua raws li cov qauv xa tawm, kom ntseeg tau tias koj cov khoom tswj hwm lawv lub Hoobkas zoo txawm tias tom qab ntev - kev thauj mus los hauv hiav txwv thiab ntau yam kev tuav.
