1. Kev faib cov qib ntshiab tooj liab
ASTM UNS System (C10000 Series)
UNS (Unified Numbering System) rau tooj liab thiab tooj liab alloys muab tsib tus lej pib nrog "C". Ntshiab tooj liab ntog nyob rau hauv qhov ntau C10100 rau C13000, thiab yog categorized los ntawm oxygen cov ntsiab lus thiab purity:
Oxygen-Free Electronic Copper (OFE): Sawv cev los ntawm C10100. Nws muaj qhov purity siab heev (Ntau dua lossis sib npaug rau 99.99% Cu) thiab cov ntsiab lus tsis tshua muaj oxygen (tsawg dua lossis sib npaug li 0.001%). Nws yog tsim los ntawm non-oxidizing melting, muab lub siab tshaj plaws hluav taws xob conductivity (Ntau tshaj los yog sib npaug rau 102% IACS) thiab zoo heev tiv thaiv hydrogen embrittlement.
Oxygen-Free High Conductivity Copper (OFHC): Sawv cev los ntawm C10200. Purity Ntau dua lossis sib npaug rau 99.95% Cu, oxygen Tsawg dua lossis sib npaug li 0.001%. Nws yog tus qauv qib rau kev siv hluav taws xob ua haujlwm siab.
Electrolytic Tough Pitch Copper (ETP): Sawv cev los ntawm C11000. Purity Ntau dua lossis sib npaug rau 99.90% Cu, nrog cov ntsiab lus oxygen tswj tau (feem ntau 0.02-0.04%). Nws yog feem ntau siv dav dav-purpose ntshiab tooj liab qib, ntsuas kev ua tau zoo thiab tus nqi.
Phosphorus-Deoxidized Copper: Qib zoo li C12000 thiab C12200, muaj cov kab phosphorus rau deoxidation, txhim kho weldability.
Suav GB/T System (GB/T 5231)
Suav cov qib tooj liab ntshiab pib nrog tsab ntawv "T" (rau "Tong," txhais tau tias tooj liab). Lawv muab faib ua peb pawg tseem ceeb raws li purity thiab oxygen cov ntsiab lus:
Common Pure Copper (T-series):
T1: High purity (Ntau dua los yog sib npaug rau 99.95% Cu), tsis muaj impurities, siv rau precision hluav taws xob Cheebtsam.
T2: Qib feem ntau (Ntau dua lossis sib npaug ntawm 99.90% Cu), dav siv hauv cov xov hlau, cables, kav dej, thiab kev lag luam dav dav.
T3: Tsawg purity (Ntau dua lossis sib npaug rau 99.70% Cu), raug nqi zoo rau kev siv tsis tseem ceeb.
Oxygen-Free Copper (TU-series):
TU1: Ultra-low oxygen (tsawg dua lossis sib npaug li 0.001%), siab tshaj purity, sib npaug rau C10100.
TU2: Tsawg oxygen (tsawg dua lossis sib npaug rau 0.002%), sib npaug rau C10200.
Phosphorus-Deoxidized Copper (TP-series):
TP1 / TP2: Muaj phosphorus rau deoxidation, siv nyob rau hauv vuam thiab kub-exchanger daim ntaub ntawv.
2. Suav sib npaug ntawm C10100 thiab C11000
C10100 (Oxygen-Free Electronic Copper, OFE):
Suav sib npaug: TU1 (GB / T 5231).
Ob leeg yog ultra-high-purity, oxygen-dawb tooj liab (Cu Ntau dua lossis sib npaug li 99.99%, O Tsawg dua lossis sib npaug li 0.001%), tsim los rau kev siv hluav taws xob tseem ceeb, nqus tsev, thiab superconducting qhov twg hydrogen embrittlement yuav tsum zam.
C11000 (Electrolytic Tough Pitch Copper, ETP):
Suav sib npaug: T2 (GB / T 5231).
Ob leeg yog lub hom phiaj dav dav, siab-conductivity tooj liab uas zoo sib xws purity (Cu Ntau dua lossis sib npaug li 99.90%) thiab tswj cov pa oxygen. Lawv yog interchangeable nyob rau hauv feem ntau industrial thiab hluav taws xob daim ntaub ntawv.
Nyob rau hauv cov ntsiab lus, ntshiab tooj liab grading yog standardized thoob ntiaj teb los xyuas kom meej cov khoom sib xws. C10100 sib raug rau Tuam Tshoj tus TU1 (ultra-high-purity oxygen-dawb tooj liab), thaum C11000 sib raug rau T2 (general-purpose tough-pitch tooj liab).
