Admiralty Brass (C44300) vs Naval Brass (C46400)
Admiralty Brass (UNS C44300) thiab Naval Brass (UNS C46400) yog ob qho khoom siv tooj liab dav dav hauv kev siv marine thiab kev lag luam. Ob lub alloys yog cov tsev neeg tooj dag (tooj liab-zinc alloys) thiab muaj cov tin rau kev txhim kho corrosion. Txawm li cas los xij, lawv cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov ntawv thov tseem ceeb sib txawv vim muaj cov qauv siv hlau sib txawv.
Tshuaj muaj pes tsawg leeg thiab cov yam ntxwv tseem ceeb
Admiralty Brass (C44300):
Muaj pes tsawg leeg: Nominally 71% Cu, 28% Zn, 1% Sn, nrog rau qhov tseem ceeb ntxiv ntawm 0.02-0.10% arsenic (As) lossis cov inhibitor zoo sib xws (xws li Sb, P).
Cov yam ntxwv tseem ceeb: Qhov sib ntxiv ntawm arsenic ua haujlwm ua tus dezincification inhibitor. Cov hlau no tshwj xeeb tsim los tiv thaiv kev xaiv leaching ntawm zinc nyob rau hauv stagnant los yog qeeb - txav seawater thiab chav condensate.
Structure: Ib leeg alpha (α) theem qauv, muab kev ua haujlwm zoo thiab ua haujlwm txias.
Naval tooj dag (C46400):
Cov khoom xyaw: Nominally 60% Cu, 39% Zn, 1% Sn. Nws tsis muaj txhob txwm arsenic lossis lwm yam dezincification inhibitors.
Cov ntsiab lus tseem ceeb: Cov ntsiab lus zinc ntau dua muab nws ob -theem alpha-beta (α-β) qauv, ua rau muaj zog dua thiab ua haujlwm kub zoo dua piv rau ib zaug -theem brasses.
Ua kom pom tseeb: Optimized rau txhua yam muaj zog thiab dav corrosion kuj nyob rau hauv marine ib puag ncig.
| Parameter | Admiralty tooj dag (C44300) | Naval tooj dag (C46400) |
|---|---|---|
| Copper (Cu) | ~71% | ~60% |
| Zinc (Zn) | ~28% | ~39% |
| Tin (Sn) | ~1% | ~1% |
| Inhibitor | Arsenic (As), tseem ceeb | Tsis txhob txwm |
| Phase Structure | Alpha (α) | Alpha{0}}Beta (α-β) |
| Tensile zog | ~ 380 MPa (55 ksi) | ~ 450 MPa (65 ksi) |
| Machineability | Ncaj ncees (20% ntawm dawb- txiav tooj dag) | Zoo (30% ntawm dawb- txiav tooj dag) |
Tej kev siv
Admiralty Brass (C44300):
Kev Siv Tseem Ceeb: Kub exchanger thiab condenser raj nyob rau hauv marine, lub zog tsim (tshwj xeeb tshaj yog cov nroj tsuag ntug dej hiav txwv), petrochemical, thiab desalination industries.
Piv txwv li: Surface condensers, evaporator thiab distiller raj, roj txias tubes.
Naval tooj dag (C46400):
Kev Siv Tseem Ceeb: Marine hardware thiab structural Cheebtsam xav tau lub zog thiab corrosion kuj.
Piv txwv li: Cov kiv cua shafts, twj tso kua mis shafts, valve stems, txiv ntseej, bolts, marine fittings, bushings, thiab architectural trim nyob rau hauv marine ib puag ncig.
Cov txheej txheem xaiv
Xaiv Admiralty Brass (C44300) thaum:
Daim ntawv thov suav nrog nyias- phab ntsa tubing rau kev sib pauv cua sov.
Ib puag ncig kev pabcuam suav nrog kev nyob ruaj khov, qeeb - txav mus los, lossis dej tsis txaus (muaj kev pheej hmoo siab ntawm dezincification).
Corrosion tsis kam yog qhov tsim qauv tseem ceeb tshaj lub zog tensile.
Xaiv Naval Brass (C46400) thaum:
Cov khoom siv yog cov khoom thauj -cov kabmob (ncej, haum, fastener) raug rau cov neeg kho tshuab kev nyuaj siab.
Ib puag ncig yog kev ywj pheej ntws, dej hiav txwv huv.
Zoo machinability los yog kub ua hauj lwm (forging) yog yuav tsum tau.
