Tungsten Hlau (W) & Tungsten Powder 99.9% purity
Tungsten qwsyog nias thiab sintered los ntawm peb lub siab purity tungsten hmoov. Peb cov pas nrig tungsten ntshiab muaj 99.96% tungsten purity thiab 19.3g / cm3 raug ntom ntom. Peb muab tungsten rods nrog diameters li ntawm 1.0mm mus rau 6.4mm los yog ntau tshaj. Kub isostatic nias ua kom peb cov tungsten rods tau ib tug siab ceev thiab nplua grain loj.
tungsten hmoovFeem ntau yog tsim los ntawm kev txo qis hydrogen ntawm high-purity tungsten oxides. UrbanMines muaj peev xwm muab tungsten hmoov nrog ntau qhov sib txawv ntawm cov nplej. Tungsten hmoov feem ntau tau nias rau hauv cov tuav, sintered thiab forged rau hauv nyias rods thiab siv los tsim cov noob filaments. Tungsten hmoov kuj tseem siv rau hauv kev sib cuag hluav taws xob, airbag xa cov tshuab thiab ua cov khoom tseem ceeb siv los tsim tungsten hlau. Cov hmoov kuj tseem siv rau hauv lwm yam kev siv tsheb thiab aerospace.
