1. General Temperature Resistance Range of Copper Alloys
Copper alloys tuaj yeem muab faib ua peb pawg dav raws li lawv qhov kub thiab txias, cuam tshuam txog kev lag luam tawm ntawm cov ntsiab lus alloying (uas txhim kho lub zog / oxidation tsis kam tab sis tuaj yeem txo cov ductility ntawm qhov siab):
| Alloy Qeb | Hom Kev Ua Haujlwm Kub Ua Haujlwm | Cov kev txwv tseem ceeb |
|---|---|---|
| Tooj liab (Cu) | -200 ° txog 250 ° F (-328 ° F txog 482 ° F) | Tshaj 300 degree: maj mam oxidation (cov ntaub ntawv Cu₂O / CuO scale) thiab txo tensile zog; qis dua -200 degree: me ductility poob tab sis tsis muaj pob txha tawg. |
| Brass (Cu-Zn) | -100℃rau 200℃(-148℃F txog 392℃F) | Cov ntsiab lus zinc siab (Ntau dua lossis sib npaug rau 30% Zn): Ua rau dezincification thiab kev ntxhov siab tawg saum toj 200 degree; qis- kub brittleness (tshwj xeeb tshaj yog + tooj dag) hauv qab -100℃. |
| Bronze (Cu-Sn/Al/Ni) | -250℃rau 400℃(-418℃F txog 752℃F) | Tin bronze: Oxidation tsis kam poob siab tshaj 350 degree; txhuas / npib tsib xee tooj liab: Superior siab - kub lub zog tab sis tej zaum yuav soften saum 450℃. |
| Tshwj xeeb Copper Alloys (Cu-Ni, Cu-Cr-Zr) | -270℃rau 600℃(-454℃F txog 1112℃F) | Engineered rau huab cua kub: Cu-Ni resists cryogenic brittleness; Cu-Cr-Zr tuav lub zog ntawm qhov kub siab los ntawm nag lossis daus hardening. |
2. Summary of Temperature-Resistant Copper Alloy Qib
| Kev Pabcuam | Cov qib pom zoo | Qhov kub thiab txias | Cov ntawv thov tseem ceeb |
|---|---|---|---|
| Siab -Tsub | C70600, C71500 (Cu-Ni); C61400, C63000 (Al Bronze); C18150, C18200 (Cu-Cr-Zr); C65500 (Si Bronze); C75200 (Nickel Silver); C52100 (Phosphor Bronze); C18660 (Cu-Mg); C19900 (Cu-Ti); C15000 (Cu-Zr); C18000 (Cu{19}}Cr) | Mus txog 600℃(1112℃F) | Thaum tshav kub kub exchangers, cav Cheebtsam, rauv qhov chaw, hluav taws xob tiv tauj |
| Tsawg- Kub | C70600, C71500 (Cu-Ni); C10200, C11000 (OFC); C61400 (Al Bronze); C65500 (Si Bronze); C52100 (Phosphor Bronze); C18660 (Cu-Mg); C19900 (Cu-Ti); C15000 (Cu-Zr); C18000 (Cu-Cr); C75200 (Nickel Nyiaj) | Mus txog -270℃(-454℃F) | LNG cia, khoom siv cryogenic, Arctic marine qauv |
Los ntawm kev xaiv cov qib alloy tsim nyog raws li qhov xav tau ntawm qhov kub thiab txias ib puag ncig, cov kws tsim khoom tuaj yeem ua kom pom kev ua haujlwm zoo, ua haujlwm ntev, thiab kev nyab xeeb hauv cov ntawv thov tseem ceeb -los ntawm cov tshuab roj cryogenic mus rau siab -kub siv tshuab.
