C14700 Cov Khoom Siv Tshuaj
Cov khoom siv tshuaj ntawm tooj liab C147 sib txawv raws li nws cov muaj pes tsawg leeg, tab sis feem ntau, nws muaj kev tiv thaiv zoo heev rau oxidation thiab ntau cov kua qaub. Nws kuj muaj cov khoom siv hluav taws xob zoo heev thiab lub zog siab ntawm qhov kub siab.
C14700 Mechanical Properties
Tooj C147 muaj lub zog siab thaum ua haujlwm txias lossis kho cua sov. Nws kuj muaj zoo ductility thiab toughness nrog zoo heev formability tag nrho. Qhov no ua rau nws zoo rau cov ntawv thov uas yuav tsum tau khoov lossis tsim yam tsis muaj kev tawg lossis tawg. Lub zog kub kub yog lwm qhov tseem ceeb ntawm cov hlau no vim nws nthuav tawm lub zog tensile zoo dua li lwm cov ntaub ntawv ntawm qhov kub txog li 350 degree / 662 degree F.
| Cov khoom | Metric | Imperial |
|---|---|---|
| Tensile zog | 221-393 MPa | 32100-57000 psi |
| Yield zog (nyob ntawm temper) | 69-379 MPa | 10000-55000 psi |
| Elongation ntawm tawg (hauv 203.2 hli) | 52% | 52% |
| Modulus ntawm elasticity | 117 GPa | 17 000 ksg |
| Poisson tus ratio | 0.34 | 0.34 |
| Machinability (UNS C36000 (dawb-txiav tooj dag)=100%) | 85% | 85% |
| Shear modulus | 44 gpa ua | 6380 ua |
C14700 Lub cev muaj zog
Copper C147 muaj qhov ntom ntawm 8 g / cm3, uas ua rau nws sib zog dua li cov hlau thiab alloys feem ntau siv hauv kev tsim kho lossis chaw tsim khoom. Nws kuj tseem muaj qhov qis melting ntawm 845 degree / 1553 degree F, uas ua rau nws yooj yim rau vuam yog tsim nyog. Nws cov thermal expansion coefficient yog 17 x 10-6 K-1, uas txhais tau hais tias nws yuav nthuav me ntsis thaum cua sov tab sis tsis txaus los ua teeb meem loj thaum siv hauv cov ntawv thov uas qhov kub thiab txias hloov tsis tu ncua.
| Cov khoom | Metric | Imperial |
|---|---|---|
| Qhov ntom | 8.94 g/m² | 0.323 lb/in3 |
| Melting point | 1067 degree | 1953 degree F |

C14700 siv
Nws kuj yog feem ntau siv rau cov ntawv thov uas yuav tsum tau muaj qhov kub thiab txias, xws li cov khoom siv hauv tsheb lossis cov khoom siv hauv aerospace, vim tias nws tsis poob lub zog txawm tias qhov kub siab tshaj 350 degree / 662 degree F. Cov khoom no feem ntau yog machined rau hauv kev cai qhov chaw rau ntau yam. tej yaam num vim nws zoo formability.
Corrosion Resistance
Copper C147 feem ntau yog siv rau hauv kev lag luam xws li cov khoom siv hluav taws xob vim nws zoo heev corrosion kuj thiab hluav taws xob conductivity zog.
Thaum tshav kub kub Resistance
Copper C147 nthuav tawm cov cua sov ua haujlwm zoo nrog kev sib tw me me thaum raug kub txog 350 degree / 662 degree F.
Kev kho cua sov
Kev kho cua sov tuaj yeem ua tiav yog tias xav tau tab sis feem ntau tsuas yog cov cuab yeej tshwj xeeb xws li hardness yuav tsum tau ua tiav vim tias cov khoom no twb muaj ntau yam tsim nyog tawm ntawm lub thawv.
Tshuab dhos
Machining Copper C147 zoo ib yam li lwm yam hlau. Txawm li cas los xij, yuav tsum tau saib xyuas tshwj xeeb vim nws qhov softness piv rau lwm cov hlau xws li steel lossis aluminium, uas muaj cov ntsiab lus melting ntau dua tooj liab c14 7. Tsis tas li ntawd, cov cuab yeej txiav yuav tsum tau ua kom ntse, vim tias cov cuab yeej npub tuaj yeem ua rau hnav ntxov ntxov ntawm cov khoom txiav.
Vuam
Vuam tooj liab c14 muaj pes tsawg tus txheej txheem vuam, suav nrog TIG, MIG, oxy-acetylene, thiab lwm yam tuaj yeem ua tau xya. Txawm li cas los xij, ib qho yuav tsum tau ceev faj txog kev nyab xeeb kom raug vim qhov vuam ua rau muaj qhov ci ntsa iab uas tuaj yeem cuam tshuam cov khoom siv hluav taws xob nyob ze ntawm thaj chaw ua haujlwm. Tsis tas li ntawd, flux yuav tsum tau ntxiv ua ntej vuam pib los tiv thaiv oxidation tsis tshwm sim thaum lub sij hawm txheej txheem.
