Cov khoom siv ntawm cov cua sov hlau ntawm ib lub taub hau hluav taws xob cua sov raj yog txawv, ib qho yog tungsten hlau thiab lwm yam yog carbon fiber:

Tungsten hlau yog siv rau cov cua sov hlau ntawm Tungsten Infrared Cua sov Tube. Tungsten filaments feem ntau yog siv los ua cua sov filaments (filaments) nyob rau hauv cov roj teeb thiab tungsten halogen teeb. Tungsten filaments siv los ua ntau lub cev luminous nyob rau hauv qhov muag teev kuj yuav tsum tau doped nrog ib tug me me ntawm cov poov tshuaj, silicon thiab txhuas oxides thaum lub sij hawm smelting txheej txheem. Lub resistivity ntawm tungsten hlau yog 5.3 * 10 ^ -8. Tungsten muaj lub siab melting point, siab resistivity, zoo zog, thiab tsawg vapor siab. Nws yog cov khoom siv zoo tshaj plaws rau kev ua cua sov ntawm cov hlau (filaments) ntawm cov hlau. Thaum cov tam sim no dhau los ntawm tungsten hlau thiab yog rhuab mus rau ib qho kub, qhov kev tiv thaiv tus nqi ntawm tungsten hlau kuj nce mus rau ib qho nqi (feem ntau, tus nqi ntawm cov hlau xaim hluav taws xob nce ntxiv thaum kub nce).
