C21000 vs C26000
Nyob rau hauv lub ntiaj teb no ntawm hlau, tooj liab thiab nws alloys yog revered rau lawv cov hluav taws xob conductivity, thermal hloov, thiab corrosion kuj. Txawm li cas los xij, tsis yog txhua tus "tooj liab" yog tsim sib npaug. Ob qho ntawm feem ntau thiab feem ntau tsis meej pem tooj liab alloys yog C21000 (Gilding Hlau, 95% Copper) thiab C26000 (Cartridge Brass, 70% Copper). Txawm hais tias lawv yuav zoo ib yam li lub qhov muag tsis tau kawm, lawv cov khoom muaj pes tsawg leeg, cov khoom siv, thiab cov ntawv thov zoo sib txawv heev. Kev nkag siab txog qhov sib txawv yog qhov tseem ceeb rau engineers, designers, thiab manufacturers.
Yam Tseem Ceeb
C21000 (Gilding Hlau): Qhov no yog tooj liab-zinc alloy nrog cov ntsiab lus tooj liab siab heev (94-96%). Nws tsuas muaj 4-6% zinc. Nws zaum ntawm ciam teb ntawm cov tooj liab ntshiab thiab tsev neeg tooj dag.
C26000 (Cartridge Brass): Qhov no yog ntau hom tooj dag. Nws yog tooj liab-zinc alloy nrog "tus qauv" zinc ntsiab lus ntawm 28-33% (nominally 70% Cu, 30% Zn).
Cov khoom tseem ceeb thiab kev ua tau zoo
| Khoom | C21000 (Gilding hlau) | C26000 Cartridge tooj dag | Winner & Implication |
|---|---|---|---|
| Xim | nplua nuj, liab doog- tooj liab xim (ze rau tooj liab ntshiab). | Distinctive bright yellow/golden xim. | C21000 rau "tooj liab" zoo; C26000 rau " tooj dag" saib. |
| Corrosion Resistance | Zoo heev, ze rau cov tooj liab ntshiab. High resistant rau atmospheric, dej tshiab, thiab seawater corrosion. | Zoo, tab sis dezincification (xaiv zinc leaching) tuaj yeem tshwm sim hauv qee qhov dej. Ntau raug rau kev ntxhov siab corrosion cracking. | C21000. Zoo dua rau qhov chaw hnyav lossis ntub dej qhov twg corrosion yog qhov kev txhawj xeeb tseem ceeb. |
| Formability & Machinability | Ua haujlwm txias txias thiab ductility. Cov machinability tsis zoo (nyob ib ncig ntawm 20% ntawm CDA nplai, qhov twg dawb - txiav tooj dag yog 100%). | Exceptional txias workability (tus qauv rau sib sib zog nqus nqus thiab stamping). Zoo machinability (nyob 30%). | C26000. Qhov kev xaiv meej meej rau cov khoom tsim, cov casings, thiab cov ntawv thov uas yuav tsum tau siv dav siv tshuab. |
| Lub zog & Hardness | softer thiab tsawg zog nyob rau hauv nws lub xeev annealed. Yooj yim zog los ntawm kev ua haujlwm txias. | Muaj zog thiab nyuaj tshaj C21000 nyob rau hauv sib npaug tempers. Ua kom muaj zog ntau dua los ntawm kev ua haujlwm txias. | C26000. Zoo dua rau cov ntawv thov uas xav tau ntau dua mechanical zog. |
| Hluav taws xob & Thermal conductivity | High conductivity (~ 56% IACS), thib ob tsuas yog tooj liab ntshiab ntawm cov alloys. | Nruab nrab conductivity (~ 28% IACS) vim muaj zinc ntau dua. | C21000. Superior rau hluav taws xob springs, terminals, thiab thermal Cheebtsam. |
| Nqi | Siab dua, vim nws cov ntsiab lus tooj liab siab. | Feem ntau kev lag luam ntau dua, vim zinc tsis tshua kim dua tooj liab. | C26000. Tus nqi ntau dua - zoo rau siab - ntim ntau lawm. |
