Tungsten tooj liab alloy muaj ntau qhov zoo vim nws qhov tshwj xeeb sib xyaw ntawm tungsten thiab tooj liab. Nws tau lees paub rau nws cov thermal conductivity, zoo heev hluav taws xob conductivity, thiab superior zog. Ntxiv nrog rau cov yam ntxwv zoo kawg li no, tungsten tooj liab alloy kuj tseem tiv taus hnav thiab tsim kua muag.
Tungsten tooj liab alloy feem ntau tuaj nyob rau hauv ntau yam ntaub ntawv xws li rods, nplooj ntawv, thiab nyob ntawm tej. Nws tuaj yeem raug molded rau hauv cov duab sib txawv thiab cov qauv tsim, uas ua rau nws muaj ntau yam khoom siv rau ntau yam kev siv. Tsis tas li ntawd, nws cov qib siab ntawm machinability ua rau nws yooj yim rau kev ua haujlwm nrog thiab tso cai rau kev txiav thiab ua kom zoo. Dimensions ntawm tungsten tooj liab alloy hauv peb lub tuam txhab:
Bars tuaj yeem ncav cuag qhov ntev ntawm {{0}}mm, xws li 0.6-100mm
Board, nrog qhov tsawg kawg nkaus thickness ntawm 0.6mm, dav ntawm 50-300mm, thiab ib tug ntev ntawm 100-500mm
Cov kav dej thiab cov nplhaib tuaj yeem hloov kho raws li tus neeg siv khoom loj, nrog rau qhov tsawg kawg nkaus phab ntsa thickness ntawm 1 hli
Kev siv tungsten tooj liab alloy muaj ntau yam thiab ntau yam. Nws yog feem ntau siv nyob rau hauv zus tau tej cov hluav taws xob tiv tauj thiab hluav taws xob qhov chaw vim nws superior conductivity. Ntxiv mus, nws yog dav siv nyob rau hauv daim ntawv thov uas yuav tsum tau high tshav kub kuj, xws li cov qhov cub thiab hluav taws xob shielding. Nws qhov tshwj xeeb hnav tsis kam kuj ua rau nws zoo heev rau kev siv hauv qhov chaw hnav siab, xws li cov cuab yeej siv thiab cov dab dej kub.
Tungsten tooj liab alloy yog cov khoom siv zoo heev nrog cov khoom zoo uas ua rau nws muaj txiaj ntsig zoo rau ntau yam kev siv. Nws cov thermal thiab hluav taws xob conductivity, zoo heev zog, thiab superior hnav tsis kam ua rau nws zoo tagnrho xaiv rau ntau yam lag luam thiab chaw.
