Tungsten Boat Description

Tungsten nkoj yog tsim los ntawm kev txiav, khoov, vuam, thiab riveting tungsten nplooj ntawv. Tungsten nkoj tuaj yeem siv rau hauv kev lag luam teeb, hluav taws xob thiab tub rog. Nws kuj tseem siv tau los ua lub thawv rau lub ntiaj teb tsis tshua muaj smelting.

SSC tshwj xeeb hauv kev muab cov nkoj siab purity hlau nrog ntau qhov ntev. Kev cai configurations muaj.

tungsten nkoj, pob tawb thiab filaments yog ua los ntawm qib siab tungsten. Ntawm tag nrho cov hlau nyob rau hauv daim ntawv ntshiab, tungsten muaj qhov siab tshaj plaws melting point, qhov qis tshaj vapor siab ntawm qhov kub siab tshaj 1650 degree (3000 degree F), lub zog tensile siab tshaj plaws, thiab qis tshaj coefficient ntawm thermal expansion ntawm cov hlau ntshiab. Qhov kev sib xyaw ua ke ntawm cov khoom no ua rau tungsten yog cov khoom siv zoo tshaj plaws rau evaporation qhov chaw.
