Qhov txawv ntawm OFHC thiab ETP tooj liab
I. Core Qhov txawv
Qhov sib txawv tseem ceeb ntawm ETP tooj liab (C11000) thiab oxygen - tooj liab dawb (C10200/C10100) yog los ntawm lawv cov txheej txheem deoxidation tag nrho. ETP tooj liab siv cov tshuaj deoxidation txoj kev, siv qhov sib ntxiv ntawm phosphorus rau kev sib raug zoo nrog oxygen thiab yog li ua tiav deoxidation; Yog li ntawd, nws cov ntsiab lus oxygen feem ntau tsis tshaj 0.06%, txawm hais tias cov kab ntawm cuprous oxide (Cu₂O) suav nrog yuav nyob hauv cov khoom siv.
Hauv qhov sib piv, oxygen- tooj liab dawb ua tiav deoxidation los ntawm kev tswj xyuas nruj ntawm cov txheej txheem smelting-ib txoj kev siv lub cev uas tsis muaj kev qhia txog cov tshuaj deoxidizing. Raws li qhov tshwm sim, nws cov ntsiab lus oxygen tsawg heev -tsis pub tshaj 0.001% rau C10200 thiab 0.0005% rau C10100-yielding microstructure uas yog tshwj xeeb ntshiab thiab zoo ntawm oxides.

OFHC tooj liab nthuav tawm hluav taws xob thiab thermal conductivity uas yog me ntsis zoo dua ntawm ETP tooj liab, muaj cov hluav taws xob conductivity ntawm 101-102% IACS thiab thermal conductivity ntawm 395-405 W / m·K. Tsis tas li ntawd, nws ua kom pom qhov tshwj xeeb siab - qhov kub thiab txias, tsis tshua muaj - kub toughness, tsis kam mus rau hydrogen embrittlement, thiab lub tshuab nqus tsev outgassing kev ua tau zoo, ua rau nws zoo tagnrho rau kev ua haujlwm huab cua.
Hauv qhov sib piv, ETP tooj liab- nrog rau hluav taws xob conductivity ntawm kwv yees li 100% IACS thiab thermal conductivity ntawm 390-400 W/m·K- muaj peev xwm ua tau raws li cov qauv kev cai rau hluav taws xob thiab thermal conduction; Txawm li cas los xij, nws muaj kev cuam tshuam rau hydrogen embrittlement ntawm qhov kub thiab txias thiab nthuav tawm lub tshuab nqus tsev ntau dua, ua rau nws tsis tshua muaj kev ntseeg siab tshaj OFHC tooj liab rau ntev - siv nyob rau hauv ib puag ncig hnyav. Cov kev ua tau zoo no sib txawv ntawm ob qib tooj liab txoj hauj lwm OFHC tooj liab raws li qhov kev xaiv zoo tshaj plaws rau siab -kawg daim ntawv thov, thaum ETP tooj liab tseem haum rau dav dav - lub hom phiaj xwm txheej.
III. Kev sib piv ntawm cov khoom ua haujlwm
- Cold Workability: Ob qho tib si muaj kev ua haujlwm txias txias; ETP tooj liab yog me ntsis superior nyob rau hauv cov nqe lus ntawm kev ua hauj lwm - hardening tus nqi.
- Kev Ua Haujlwm Kub Kub: ETP Copper > Oxygen- Dawb Copper (ETP tooj liab ua kom pom kev tiv thaiv ntau dua rau siab -kub oxidation).
- Machinability: ETP Copper yog qhov zoo dua (pom zoo dua nti-cov yam ntxwv tawg).
- Kev Kho Hniav: Oxygen- tooj liab dawb muaj qhov zoo tshaj plaws adhesion rau electroplating thiab txheej txheej.
xaus
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm OFHC tooj liab thiab ETP tooj liab qhov chaw ntawm purity, oxygen cov ntsiab lus, kev ua tau zoo, thiab tus nqi. OFHC tooj liab nta siab purity thiab tsis tshua muaj oxygen cov ntsiab lus, nthuav tawm cov hluav taws xob zoo thiab thermal conductivity, thiab ua kom pom kev muaj zog nyob rau hauv kev ua haujlwm hnyav; Txawm li cas los xij, nws nqa tus nqi siab dua thiab ntsib cov khoom siv nruj, ua rau nws zoo tagnrho rau kev ua haujlwm siab -kev ua haujlwm zoo- xws li kev koom ua ke nrog steel tubing rau siab -kawg precision khoom thiab kev tsim khoom siab heev.
Conversely, ETP tooj liab muaj nruab nrab purity, zoo machinability, qis nqi, thiab ntau txaus, rendering nws haum rau niaj hnub daim ntaub ntawv nyob rau hauv lub steel tubing kev lag luam thiab rau kev lag luam lub hom phiaj.
