Hauv tsev neeg tooj dag, C28000 (Muntz Hlau) thiab C36000 (Dawb-Txiav tooj dag) sawv cev rau lub hauv paus diav rawg hauv txoj kev. Lawv cov kev xaiv txhais cov txheej txheem tsim khoom tseem ceeb rau ib feem. C28000 yog tus yeej ntawm kev ua haujlwm txias thiab lub zog, thaum C36000 yog tus huab tais tsis sib haum xeeb ntawm kev ua haujlwm siab - nrawm. Nkag siab txog lawv qhov sib txawv me me yog qhov tseem ceeb rau kev ua kom zoo dua tus nqi, kev ua tau zoo, thiab kev tsim khoom.
Tshuaj muaj pes tsawg leeg
C28000 Brass (60/40 Brass): Muaj 60.0-63.0% Copper thiab Tsawg dua lossis sib npaug rau 0.30% Lead (feem ntau<0.07%). It is classified as a low-lead or "lead-free" brass. The balance is zinc. Its structure is alpha-beta (α+β).
C36000 Brass (Free-Txiav Brass): Muaj 60.0-63.5% Copper thiab txhob txwm siab siab 2.5-3.7% Lead. Cov hlau lead muaj nyob raws li cov khoom tawg hauv lub microstructure. Qhov sib npaug yog zinc. Nws cov qauv kuj yog alpha-beta tab sis hloov kho los ntawm txhuas.
Mechanical & Physical Properties
| Khoom | C28000 Brass (Tsawg-Lead) | C36000 Brass (High-Lad) | Yog vim li cas rau Design |
|---|---|---|---|
| Lub ntsiab yam ntxwv | Kev ua haujlwm txias txias zoo heev | Exceptional Machinability | Txhais txoj kev tsim ua tau. |
| Machinability Rating | Ncaj ncees (~ 40% ntawm C36000) | Zoo heev (100% benchmark) | C36000 ua kom nrawm nrawm, qis zog, lub neej ntev dua, thiab ua tiav zoo dua. |
| Chip Tsim | Ntev, stringy, tawv chips. | Luv luv, tawg, yooj yim tshem tawm chips. | C36000 yog qhov tseem ceeb rau automated, siab - ntim CNC machining. |
| Tensile zog | Siab dua (Annealed: Ntau dua lossis sib npaug rau 370 MPa) | qis (Annealed: ~ 310 MPa) | C28000 muab ntau dua txhua yam muaj zog hauv qhov kawg. |
| Ductility / Elongation | Zoo (~ 20% hauv annealed) | Tsawg heev (~ 15% hauv annealed) | C28000 tuaj yeem khoov tau hnyav, stamped, thiab kos; C36000 yog nkig thiab yuav tawg. |
| Kub ua haujlwm | Zoo heev | Tsis pom zoo | C28000 tuaj yeem forged; C36000 cov hlau lead ua rau "kub shortness" thiab melting. |
| Ua haujlwm txias (khoov, stamping) | Zoo heev | Neeg pluag heev | C36000 tsis haum rau ib qho tseem ceeb tshaj tawm -machining forming. |
Kev ua tau zoo & kev txiav txim siab
Corrosion & Environmental Resistance
Ob leeg muaj qhov zoo sib xws hauv paus corrosion kuj nyob rau hauv atmospheric tej yam kev mob. Txawm li cas los xij, C28000 feem ntau muaj ntug hauv qee qhov chaw aqueous vim nws cov qauv microstructure ntau homogeneous. Cov hmoov txhuas hauv C36000 tuaj yeem tsim cov chaw galvanic.
Qhov sib txawv tseem ceeb tshaj plaws yog kev tswj hwm. C28000, nrog nws cov ntsiab lus tsis tshua muaj hlau lead, tau txais kev pom zoo rau kev siv hauv cov dej haus (raws li cov qauv hauv zos xws li NSF / ANSI 61) thiab ua raws li cov kev cai nruj xws li US Safe Drinking Water Act thiab EU RoHS / REACH rau ntau daim ntawv thov. C36000 yuav luag thoob plaws ntiaj teb txwv tsis pub muaj kev sib cuag nrog dej thiab ntsib kev txwv rau cov neeg siv khoom thiab cov khoom siv hluav taws xob vim nws cov ntsiab lus txhuas siab.
Kev koom ua ke thiab ua tiav
Vuam/Brazing: C28000 tuaj yeem welded thiab brazed nrog cov txheej txheem rau tooj liab alloys. C36000 yog qhov nyuaj heev rau vuam lossis brace; cov hlau lead liquifies thiab ua rau tawg, porosity, thiab pa phem.
Plating / Finishing: Ob leeg txais plating zoo, tab sis qhov ntxeem tau ntawm machined C36000 tej zaum yuav tsum tau tshwj xeeb sealing txheej txheem los tiv thaiv plating tov entrapment.
Daim ntawv thov Domains
C28000 Brass yog "Fabricator's Alloy":
Architectural & Decorative Hardware: Hinges, locks, door handles, hniav trim uas yuav tsum tau stamping thiab dabtsi yog khoov.
Thaum tshav kub kub Exchanger Cheebtsam: Fins, daim hlau, thiab cov hlab uas yog tsim.

Txhua qhov chaw uas cov duab kawg tau ua tiav feem ntau los ntawm kev tshem tawm cov khoom (tig, milling, drilling, tapping) ntawm cov tshuab ntsia hlau tsis siv neeg lossis CNCs.
Tus Nqi & Ntau Lawm Kev Lag Luam
Khoom siv:C36000 feem ntau nqa tus nqi me me tshaj C28000 vim yog cov hlau lead ntxiv thiab nws cov xwm txheej raws li cov khoom tshwj xeeb machining feedstock.
Tus nqi tag nrho:Qhov no yog qhov kev txiav txim siab. Rau ib tug complex:
Yog tias nws tuaj yeem raug stamped lossis tsim los ntawm daim ntawv / kauj, siv C28000 yuav pheej yig dua vim yog siab - nrawm, qis - khib nyiab ntau lawm.
Yog hais tias ib feem yuav tsum tau complex 3D duab, nruj threads, los yog dhuav qhov, machining nws los ntawm C36000 pas nrig yuav ua tau ntau yig dua machining C28000. Kev txuag hauv lub sijhawm machining, cov cuab yeej hnav, thiab kev siv hluav taws xob ntau dhau ntawm cov khoom siv hwm.
