Hluav taws xob conductivity ntawm tooj liab alloy
Cov hluav taws xob conductivity ntawm tooj liab alloy feem ntau yog siv los ua tus qauv ntawm purity. Qhov siab tshaj plaws conductivity yog tau nrog ntshiab tooj liab. Rau qhov yooj yim ntawm kev sib piv, cov conductivity ntawm cov khoom lag luam ntshiab tshaj plaws tau teeb tsa raws li International Annealed Copper Standard (IACS) qee xyoo dhau los. 100% IACS sib raug rau 0.5800 microhm?¹.cm?¹. Niaj hnub nimno refining cov tswv yim tam sim no niaj hnub tsim tooj liab ntawm purity siab dua, uas tshaj 100% IACS.
C11000
Electrolytic tawv pitch tooj liab, yog cov hlau feem ntau siv hauv cov pab pawg, nrog cov hluav taws xob conductivity ntawm 100% IACS lossis zoo dua. Nws yog tsim los ntawm melting cathode tooj liab nyob rau hauv ib tug me ntsis txo qhov cua, thiab tej zaum yuav muaj txog li 0.05% ntawm oxygen li cuprous oxide. Thaum rhuab saum toj no txog 370 degree nyob rau hauv lub xub ntiag ntawm hydrogen (xws li cov pa roj) nws yuav ua tau hydrogen embritttled. C11000 tsis haum rau cov roj vuam thiab kub kub brazing.
C10100 thiab C10200
Oxygen-dawb tooj liab alloys, yog tsim los ntawm melting cathode tooj liab nyob rau hauv tsawg hydrogen, txo tej yam kev mob, tsis muaj ntxiv ntawm ib tug deoxidising neeg sawv cev. Cov hlau no muaj cov conductivity siab, tshwj xeeb tshaj yog siab ductility, tsis tshua muaj roj permeability, kev ywj pheej los ntawm hydrogen embrittlement thiab tsawg outgassing nyob rau hauv lub nqus tsev vacuum.
C10300
Oxygen-free ntxiv uas tsis muaj phosphorus tooj liab alloy, yog tsim los ntawm melting cathode tooj liab nyob rau hauv tsis tshua muaj tej yam kev mob, deoxidising nrog phosphorus thiab tswj rau ib tug tsawg residual phosphorus. Cov khoom siv tshuab zoo ib yam li C10100 thiab C10200 ntawm tus nqi qis.
C11600
Silver bearing tawv pitch tooj liab alloys, yog siv rau qhov uas tsis kam mus softening nyob rau hauv lub txias-ua hauj lwm mob siab tshaj li 200 degree yuav tsum tau. Silver tsis txo qhov conductivity ntawm tooj liab.
C12200
Phosphorus deoxidised tooj liab, tau ua weldable thiab brazeable los ntawm deoxidising nrog phosphorus. Nws yog siv rau cov khoom tiaj tus, tubing thiab cov ntawv zoo sib xws. Phosphorus ho txo cov conductivity, uas yuav mus li 70% IACS. C14210, Phosphorus deoxidised arsenical tooj liab alloys, kuj muaj ib qho me me ntawm arsenic, uas ua rau cov softening kub thiab ho txhim kho corrosion kuj nyob rau hauv dej.
C14700
Sulfur bearing tooj liab, muaj sulfur ntxiv los txhim kho machinability. Qhov txo qis ntawm conductivity yog me ntsis, txog li 95% IACS.
Qhov zoo ntawm tooj liab alloy
Copper alloys muaj ntau yam txiaj ntsig thiab tshwj xeeb yog lub hauv paus tseem ceeb hauv cov khoom siv hluav taws xob, tshwj xeeb tshaj yog thaum ua kom yooj yim rau cov txheej txheem ntawm hluav taws xob faib hluav taws xob, txo tus nqi tag nrho, thiab ua kom yooj yim dua. Lawv superior hluav taws xob thiab thermal conductivity tsuas yog sib txuam los ntawm cov nyiaj, ua rau nws muaj kev xaiv ntau dua.
Whilst tooj liab feem ntau cuam tshuam nrog kev siv hluav taws xob, nws yog qhov tseeb siv ntau dua hauv kev tsim vaj tsev. Nws yog kev ua haujlwm ntev, kev tiv thaiv corrosion thiab zoo nkauj zoo nkauj ua rau tooj liab alloy nyiam cov hlau rau vov tsev, cladding thiab cov khoom los nag.
