Large grain size tungsten trioxide (wide spec tungsten trioxide) is a lower grade of tungsten trioxide powder that has the same density with tungsten trioxide, but at a much lower cost than pure WO3 powder. Tungsten trioxide with large grain size is specifically developed for various applications where the high density of tungsten is desired yet extreme purity is not required.
Application of Large Grain Size Tungsten Trioxide
To be applied for producing tungsten counterweight such as golf head counterweight, motorcycle counterweight, counterweight in shipbuilding industry, and so on.
