Copper-tungsten alloy, tseem hu ua tungsten tooj liab, yog cov khoom siv sib xyaw ua ke nrog tooj liab thiab tungsten. Cov khoom xyaw feem ntau yog sib xyaw ntawm tooj liab thiab tungsten, feem ntau 10% mus rau 50% tungsten los ntawm qhov hnyav. Cov hlau yog tsim los ntawm cov hmoov hlau metallurgy txheej txheem uas tungsten hmoov yog tov nrog tooj liab hmoov thiab ces sintered ntawm qhov kub thiab txias los tsim cov khoom sib xyaw.

Tooj-tungsten alloys muaj nuj nqis rau lawv cov khoom sib xyaw tshwj xeeb, suav nrog tooj liab siab thermal thiab hluav taws xob conductivity thiab tungsten lub zog siab, hardness thiab hnav tsis kam. Cov khoom no ua rau tooj liab-tungsten alloys haum rau ntau yam kev siv xws li hluav taws xob tiv tauj, tsis kam vuam electrodes, EDM (electrical discharge machining) electrodes thiab lwm yam kub thiab siab hnav daim ntaub ntawv uas hluav taws xob thiab thermal conductivity yog ua ke nrog siab zog thiab kuj yuav tsum tau. . Abrasive.

Embedding tungsten hauv tooj liab tsim cov khoom sib xyaw uas sib xyaw ua ke cov khoom muaj txiaj ntsig ntawm ob qho tib si hlau. Tungsten muaj lub zog siab, hardness thiab hnav tsis kam, thaum tooj liab muaj thermal thiab hluav taws xob conductivity. Los ntawm embedding tungsten rau hauv tooj liab, lub resulting alloy exhibits ib tug tshwj xeeb ua ke ntawm cov khoom, ua rau nws haum rau ntau yam kev siv uas yuav tsum tau muaj zog thiab zoo hluav taws xob conductivity. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm tungsten-tooj ​​tooj liab electrodes, tungsten muab lub hardness thiab hnav tsis kam yuav tsum tau ua cov ntaub ntawv nyuaj, thaum tooj liab ua kom muaj cua sov dissipation thiab hluav taws xob conductivity. Ib yam li ntawd, nyob rau hauv cov ntaub ntawv ntawm tooj liab-tungsten alloys, kev sib xyaw ntawm tungsten thiab tooj liab muab cov khoom zoo heev thermal thiab hluav taws xob conductivity nrog rau siab zog thiab hnav tsis kam.

tooj liab yog ib tug zoo conductor ntawm hluav taws xob tshaj tungsten. Tooj liab paub txog nws cov khoom siv hluav taws xob zoo heev, uas ua rau nws cov khoom xaiv rau cov xov hlau, hluav taws xob tiv tauj, thiab ntau yam kev siv hluav taws xob. Ntawm qhov tod tes, tungsten muaj qis hluav taws xob conductivity piv rau tooj liab. Thaum tungsten muaj nuj nqis rau nws qhov siab melting point, lub zog, thiab hardness, nws tsis zoo li tus neeg xyuas pib hluav taws xob zoo li tooj liab. Yog li ntawd, rau cov ntawv thov uas muaj hluav taws xob conductivity yog qhov tseem ceeb, tooj liab yog thawj qhov kev xaiv tshaj tungsten.
