Tungsten Powder

Tungsten Powder

Description:
LTWM can supply 99.95 % (calculated by subtractive method) super purity tungsten powder as raw material. These superior dark grey powders can be divided into several types according to different Fsss particle sizes and oxygen contents, including No.10, No.15, No.20, No.30, No.40, No.55 and No.70 tungsten powders. Meanwhile, they also can be divided into FW-1, FW-2 and FWP-3 grades tungsten powders on the basis of different impurity contents.

Packing and Shipping:
We deliver pure tungsten powder in plywood cases by ocean shipping or air transportation.
