1. Oxygen-Ntshav tooj liab (OFC)
Oxygen- tooj liab dawb yog tsim los ntawm kev tswj cov pa oxygen, nrog cov ntsiab lus oxygen feem ntau qis dua 10 ppm. Nws zam hydrogen embrittlement ntawm qhov kub thiab txias thiab muaj kev ruaj ntseg conductivity.
Cu-OF (EN) / C10100 (ASTM) / TU1 (GB)
Qhov no yog qhov siab tshaj plaws -qib oxygen- dawb tooj liab nrog tsis tshua muaj impurity thiab cov ntsiab lus oxygen. Nws cov hluav taws xob conductivity tuaj yeem ncav cuag ntau dua 100% IACS, thiab nws muaj cov yas zoo heev thiab weldability. Nws yog tsuas yog siv nyob rau hauv siab -cov khoom siv hluav taws xob ua tau zoo, cov khoom siv nqus tsev vacuum, siab - cov khoom siv hluav taws xob ntau zaus, superconductor encapsulation thiab lwm yam precision teb uas yuav tsum tau muaj hluav taws xob ruaj khov heev.
TU2 (GB) / C10200 (ASTM)
Zoo ib yam li TU1, tab sis nrog me ntsis siab dua impurities, nws yog cov feem ntau siv oxygen - tooj liab dawb hauv kev lag luam. Nws sib npaug kev ua tau zoo thiab tus nqi, thiab yog siv dav hauv cables, conductors, integrated circuit lead thav duab thiab cov khoom siv vuam.
2. Tough Pitch Copper (TPC)
Nyuaj pitch tooj liab yog qhov ua tau zoo tshaj plaws thiab siv dav siv tooj liab ntshiab, nrog cov ntsiab lus oxygen feem ntau ntawm 100-650 ppm. Nws muaj kev ua tau zoo thiab kev ua haujlwm zoo, tab sis nws yooj yim rau hydrogen embrittlement nyob rau hauv siab -kub hydrogen cua.
Cu-ETP (EN) / C11000 (ASTM) / T2 (GB)
Qhov no yog cov neeg sawv cev tshaj plaws thiab feem ntau siv tawv tawv tooj liab, nrog kev ua haujlwm siab tshaj 97% IACS. Nws muaj tus nqi nruab nrab thiab kev ua haujlwm zoo heev, thiab yog thawj qhov kev xaiv rau cov khoom siv hluav taws xob thiab thermal conductive. Cov ntawv thov muaj xws li fais fab cables, busbars, motor windings, transformer coils, heat exchangers, kav dej thiab hniav tooj liab qhov chaw.
T1 (GB) / C10300 (ASTM)
High-purity tawv pitch tooj liab, nrog tsawg impurities tshaj T2, me ntsis conductivity zoo dua thiab corrosion kuj, feem ntau yog siv nyob rau hauv siab -precision hluav taws xob khoom thiab hluav taws xob connectors.
T3 (GB)
Tsawg purity dua T2, nrog cov ntsiab lus impurity siab dua, tus nqi qis, tsim nyog rau cov khoom lag luam dav dav nrog cov kev xav tau qis rau kev coj ua, xws li cov khoom siv stamping, cov khoom siv niaj hnub thiab cov khoom siv.
3. Deoxidized tooj liab
Deoxidated tooj liab yog deoxidized los ntawm phosphorus, lithium los yog lwm yam ntsiab lus, nrog cov pa oxygen tsawg heev, kev ua haujlwm zoo vuam thiab tsis muaj hydrogen embrittlement. Phosphorus-deoxidized tooj liab yog ntau tshaj.
Cu-DLP (EN) / C12000 (ASTM) / TUP (GB)
Phosphorus-deoxidized tooj liab, residual kab phosphorus txhim kho vuam thiab brazing kev ua tau zoo, tab sis me ntsis txo cov hluav taws xob conductivity (kwv yees li 85-95% IACS). Nws yog dav siv hauv cov kav dej, cov kav dej, cov kav dej tub yees, cov khoom siv hluav taws xob, HVAC thiab ntau yam khoom siv vuam.
Cu-DHP (EN) / C12200 (ASTM) / TUMn (GB)
Siab -phosphorus deoxidized tooj liab, nrog zoo weldability, haum rau txoj kev vuam cov qauv thiab cov yeeb nkab fittings uas yuav tsum tau muaj kev ua tau zoo, thiab yog cov khoom siv rau cov kav dej tooj liab thiab cov kav dej tub yees thoob ntiaj teb.
Qhov sib txawv ntawm cov qhab nia
Qhov sib txawv tseem ceeb ntawm cov qib tooj liab ntshiab nyob hauv cov ntsiab lus oxygen, qib impurity, deoxidation ntsiab lus thiab hluav taws xob conductivity:
Cov ntsiab lus Oxygen:OFC muaj cov pa oxygen qis tshaj plaws, ua raws li deoxidized tooj liab, thiab tawv pitch tooj liab muaj siab tshaj plaws. Cov ntsiab lus Oxygen txiav txim siab siab -kub stability thiab hydrogen embrittlement resistance.
Hluav taws xob conductivity:OFC > tawv pitch tooj liab > phosphorus -deoxidized tooj liab. High-conductivity scenarios nyiam oxygen-dawb lossis tawv tawv tooj liab.
Weldability:Deoxidized tooj liab yog qhov zoo tshaj plaws, tshwj xeeb tshaj yog rau siab - vuam thiab brazing.
Nqi thiab daim ntawv thov:Tough pitch tooj liab T2 / C11000 muaj tus nqi zoo tshaj -kev ua tau zoo thiab kev noj ntau tshaj; oxygen- tooj liab dawb yog siv hauv high-kawg hluav taws xob; deoxidized tooj liab yog qhov tseem ceeb hauv cov kav dej thiab vuam qhov chaw.
