Copper Properties: Lub cev muaj zog
Jun 27, 2022
Cov kab impurities nyob rau hauv liab tooj liab muaj kev cuam tshuam loj heev rau cov conductivity thiab thermal conductivity ntawm tooj liab. Ntawm lawv, titanium, phosphorus, hlau thiab silicon txo cov hluav taws xob conductivity, thaum cadmium thiab zinc muaj cov nyhuv me me. Cov khoom solubility ntawm oxygen, sulfur, selenium thiab tellurium nyob rau hauv tooj liab yog tsawg heev, thiab lawv muaj peev xwm tsim nkig tebchaw nrog tooj liab, uas muaj me ntsis cuam tshuam rau hluav taws xob conductivity, tab sis yuav txo tau machining plasticity. Thaum cov tooj liab zoo tib yam yog cua sov hauv qhov chaw uas muaj cov pa roj carbon monoxide lossis carbon monoxide, hydrogen lossis carbon monoxide tuaj yeem hnov mob yooj yim nrog Cu2O ntawm cov ciam teb los tsim cov dej kub los yog cov pa roj carbon dioxide, uas tuaj yeem tawg tooj liab. Qhov tshwm sim no feem ntau hu ua "hydrogen kab mob" ntawm tooj liab. Oxygen yog teeb meem rau lub weldability ntawm tooj liab. Bismuth los yog txhuas thiab tooj liab daim ntawv eutectic nrog tsawg melting point, uas ua rau tooj liab brittle. Lub brittle bismuth faib raws li cov ciam teb raws li ib tug nyias zaj duab xis ua tooj liab brittle. Phosphorus tuaj yeem txo cov hluav taws xob conductivity ntawm tooj liab, tab sis txhim kho cov kua dej ntawm tooj liab thiab txhim kho weldability. Raws li cov txhuas, tellurium thiab sulfur tuaj yeem txhim kho kev ua haujlwm. Lub zog tensile, elongation thiab Brinell hardness ntawm liab tooj liab annealed ntawv yog 22 ~ 25 kg / mm 2, 45 ~ 50 feem pua thiab 35 ~ 45 feem ntawm chav tsev kub.
