Micro Tungsten (W) Powder Description
Micro Tungsten (W) Powder features high purity, small particle size, small bulk density, uniform particles, high activity, large specific surface area, and extremely low oxygen content after the powder is treated with inert gas. It is easy to disperse and used in industries, currently widely used in aerospace alloys, electronic packaging alloys, electrode materials, microelectronic films, sintering aids, protective coatings, gas sensor electrodes, etc.
Micro Tungsten (W) Powder has diverse uses in traditional & high-tech industries like mechanics, electronics, aeronautics, metallurgy, chemistry, environment, etc.
