Tungsten Bar Description
Ntshiab tungsten blanks, uas yog tsim los ntawm tungsten hmoov los ntawm hmoov metallurgy, yog cov khoom nyoos los ua cov tungsten tuav. Qhov purity feem ntau yog ntau dua lossis sib npaug rau 99.95 feem pua.
Raws li qhov sib txawv ntawm cov duab sib txawv, tungsten tuav tuaj yeem muab faib ua puag ncig tungsten tuav, duab plaub tungsten tuav, square tungsten tuav, hexagonal tungsten tuav thiab lwm yam. Ntshiab tungsten tuaj yeem ua haujlwm los ntawm forging, kos duab, extruding thiab dov. Tungsten bar yog ruaj khov heev. Nws tsis hnov mob nrog huab cua, dej, HCl los yog sulfuric acid nyob rau hauv ib txwm atmospheric kub. Thaum nws yog rhuab mus rau 80 ~ 100 degree, nws yuav tsis muaj zog tiv thaiv acid. Tungsten bar yog yooj yim oxidized nyob rau hauv cov pa oxygen.
Tungsten bar tuaj yeem yuav los ntawm SSC hauv ntau lossis tsawg.
Cov tungsten tuav nrog purity ntawm 99.999 feem pua yog siv los ua cov khoom siv rau cov txheej txheem siab bearing steels, tsheb, high-speed railways, high precision khoom, thiab high-tech riam phom. Cov tungsten tuav nrog purity ntawm 99.99 feem pua yog siv los ntawm cov cuab yeej hlau hlau, cov hlau huv huv, thiab cov hlau tshwj xeeb, thiab lwm yam. Cov tungsten tuav nrog purity ntawm 99.95 feem pua yog siv los ua raw khoom rau cov hlau tshwj xeeb thiab steel hlau. Thiab nws kuj tau siv dav hauv qhov cub kub kub, lub tshuab nqus tsev vacuum, thiab sapphire siv lead ua rauv. Tungsten bar kuj tseem siv los ua phom, phom foob pob ua ntxaij, satellite dav hlau, thiab nkoj.
