Core Application Fields
Tsev Kho vajtse: qhov rooj thiab qhov rais fittings, xauv, kav dej fittings.
Cov Khoom Siv Hluav Taws Xob thiab Hluav Taws Xob: Cov Hluav Taws Xob Hluav Taws Xob, cov khoom siv hluav taws xob, hloov cov neeg sib cuag.
Mechanical Manufacturing: Screws, rivets, washers, stamped qhov chaw.
Cov khoom siv kho kom zoo nkauj: Hlau mesh, hniav strips, crafts.
Cov Khoom Siv Khoom Siv: Condenser raj, cov khoom siv hluav taws xob sib txawv (yuav tsum tau tiv thaiv los ntawm seawater corrosion).
Kev txiav txim siab ua
Txheej txheem Annealing: Yuav tsum tau annealing ntawm 550-650℃tom qab ua haujlwm txias kom tshem tawm cov kev ntxhov siab sab hauv thiab tiv thaiv kev tawg.
Vuam yuav tsum tau: nyiam siv argon arc vuam los txo cov zinc evaporation thiab pore defects.
Kev Tiv Thaiv Corrosion: Tsis txhob cuam tshuam ncaj qha rau hauv dej hiav txwv lossis ammonia ib puag ncig; nws raug pom zoo kom ntxiv txheej los yog plating.
Sib piv: H62 vs. H65 Brass
| Khoom | H62 tooj | H65 tooj |
|---|---|---|
| Kev sib xyaw (Cu / Zn) | 62% Cu, ~ 38% Zn | 65% Cu, ~ 35% Zn |
| Cov ntsiab lus tooj liab | qis | Siab dua |
| Cov ntsiab lus zinc | Siab dua | qis |
| Lub zog (tensile) | Siab dua (ntau Zn → solid- daws teeb meem) | Tsawg me ntsis |
| Hardness | Siab dua | Nruab nrab qis |
| Ductility / Formability | Zoo, tab sis tsawg dua H65 | Zoo dua - zoo dua rau kev ua haujlwm txias txias, sib sib zog nqus nqus, khoov |
| Corrosion kuj | Zoo, tab sis me ntsis qis dua H65 (Zn siab dua ua rau muaj kev pheej hmoo dezincification) | Zoo dua - siab dua Cu txhim kho kev dav dav thiab kev ntxhov siab- tiv thaiv corrosion |
| Machineability | me ntsis zoo dua (Zn siab dua txhim kho nti tawg) | Tsawg me ntsis (tab sis tseem zoo) |
| Hluav taws xob conductivity | qis (ntau Zn txo cov conductivity) | Siab dua (ze rau tooj liab ntshiab) |
| Nqi | Lower (tsawg tooj liab) | Siab dua (ntau tooj liab) |

Yuav Xaiv Li Cas – Daim Ntawv Qhia Txog Kev Txiav Txim
Xaiv H62 Brass thaum:
Tus nqi yog qhov kev txhawj xeeb tseem ceeb- koj xav tau cov khoom siv qis dua.
Siab zog thiab hnav tsis kamyog ib qho tseem ceeb tshaj li formability (xws li, cov khoom siv, fasteners, valve stems, radiator cores, los yog stamped qhov chaw nrog cov duab yooj yim).
Machining yog intensive- H62 muab kev tswj hwm nti zoo me ntsis thiab lub neej cuab yeej.
Qhov chaw ua hauj lwm yog me me(hauv tsev, qhuav, los yog maj mam corrosive).
Hluav taws xob / thermal conductivity tsis tseem ceeb.
Xaiv H65 Brass thaum:
Ua kom txias txiasyog yuav tsum tau - kos duab sib sib zog nqus, complex dabtsi yog khoov, spinning, los yog hnyav stamping (H65 muaj zoo elongation thiab tsawg dua kev pheej hmoo ntawm tawg).
Corrosion kuj tseem ceeb dua- tshwj xeeb tshaj yog nyob rau hauv moist, me ntsis acidic, los yog sab nraum zoov ib puag ncig (siab dua Cu txo dezincification).
Koj xav tau qhov chaw zoo duatom qab tsim (H65 zoo li yuav muaj tsawg dua qhov chaw).
Ib feem yuav brazed los yog soldered- siab dua Cu txhim kho kev ntub dej thiab kev sib koom ua ke.
Daim ntawv thov muaj kev vibration me ntsis lossis qaug zog- H65 qhov zoo dua ductility absorbs kev ntxhov siab zoo dua.
Cov peev nyiaj tso cai- qhov ntxiv ~ 3% tooj liab ntxiv qhov ua tau zoo rau kev xav tau siv.
