Nyob rau hauv lub ntiaj teb no ntawm tooj dag alloys, xaiv qhov tseeb yog ib qho tseem ceeb rau kev ua kom pom kev ua tau zoo, tus nqi -effectiveness, thiab manufacturability rau ib qhov project. Ob qhov feem ntau ntsib thiab qee zaum tsis meej pem qib yogH65thiabH62. Thaum lawv cov npe zoo sib xws, lawv qhov sib txawv ntawm cov khoom sib txawv ua rau cov khoom sib txawv, ua rau txhua qhov tsim nyog rau cov ntawv thov tshwj xeeb. Kab lus no rhuav tshem qhov sib txawv tseem ceeb los coj koj cov khoom xaiv.
H65 vs H62 Kev sib xyaw
Cov lej hauv cov npe qib tooj dag ncaj qha qhia lawv qhov nruab nrab tooj liab (Cu) cov ntsiab lus feem pua, nrog rau qhov seem feem ntau yog zinc (Zn). Qhov no zoo li me me variation cuam tshuam rau alloy lub microstructure thiab mechanical cwj pwm.
H65 Brass: Muaj kwv yees li 65% tooj liab thiab 35% zinc. Cov ntsiab lus tooj liab siab dua no tso nws ruaj khov hauv thaj tsam alpha ( ) tooj dag. Alpha tooj dag muaj lub ntsej muag -centered cubic crystal qauv, muab nws zoo heev ductility, txias ua hauj lwm, thiab corrosion kuj. Nws yog tus softer thiab ntau malleable.
H62 Brass: Muaj kwv yees li 62% tooj liab thiab 38% zinc. Qhov kev sib xyaw no nyob ze heev rau thaj tsam ntawm alpha-beta (+) brass theem cheeb tsam. Lub xub ntiag ntawm beta ( ) theem, uas muaj lub cev -centered cubic qauv, muab ntxiv zog thiab hardness piv rau alpha tooj dag, thaum tseem tuav tau zoo formability. Nws muaj qhov sib npaug ntawm lub zog thiab ductility.
Cov khoom sib piv & Cov ntawv thov ib txwm
| Khoom | H65 Brass (Cu ~ 65%) | H62 Brass (Cu ~ 62%) |
|---|---|---|
| Cim Cim | High ductility, zoo heev txias ua haujlwm. | Sib npaug lub zog thiab ductility, zoo kub ua haujlwm. |
| Lub zog & Hardness | Tsawg tensile zog, softer. | Siab zog tensile thiab hardness. |
| Formability | Superiorrau txoj kev txias txias- txheej txheem sib sib zog nqus (kev kos duab sib sib zog nqus, khoov, stamping). | Zoo rau kev ua kom txias; zoo dua haum rau kub forging / nias vim yog -theem. |
| Corrosion Resistance | Me ntsis zoo dua vim muaj cov ntsiab lus tooj liab ntau dua. | Zoo, tab sis marginally tsawg dua H65. |
| Cov ntawv thov siv | - Sib sib sib zog nqus- kos qhov chaw (piv txwv li, plhaub casings, intricate vaj tse) - Kub exchanger fins thiab raj - Hluav taws xob qhov hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob - Cov khoom zoo nkauj, suab paj nruag |

Yuav xaiv li cas: H65 lossis H62?
Ua ntej ua qhov tseem ceeb ntawm Cov Txheej Txheem Tsim Khoom Tseem Ceeb:
XaivH65yog tias koj qhov project cuam tshuam nrog kev kub stamping, sib sib zog nqus kos duab, los yog khoov ntau heev. Nws superior ductility tiv thaiv kev tawg thaum lub sij hawm loj deformation.
XaivH62Yog tias koj qhov project cuam tshuam nrog cov txheej txheem ua haujlwm kub (xws li forging), lossis yog tias cov khoom siv yuav tsum muaj zog ntau dua yam tsis tas yuav muaj qhov txias txias.
Txhais lub Cheebtsam lub luag haujlwm yuav tsum tau:
XaivH65rau cov khoom xav tau hluav taws xob / thermal conductivity, zoo heev corrosion kuj, thiab qaug zog kuj (xws li, springs, conductive ntsiab).
XaivH62rau qhov chaw ua haujlwm raws li cov tswv cuab, hnav cov khoom siv, lossis cov khoom siv dav dav uas muaj zog thiab tawv muaj nuj nqis nrog rau cov qauv tsim nyog.
Xav txog qhov cuam tshuam rau tus nqi:
H65 muaj cov ntsiab lus tooj liab ntau dua, ua rau nws feem ntau kim dua hauv cov khoom siv raw li H62.
H62 feem ntau muab tus nqi - qhov sib npaug ntawm kev ua tau zoo rau ntau yam kev siv engineering dav dav.
