Spherical Tungsten Powder Description
Spherical Tungsten Powder (Spherical W Powder) has a spherical appearance. Compared with ordinary tungsten powder, it has the remarkable characteristics of good powder fluidity. Besides, Spherical Tungsten Powder has the feature of high density, high melting point, good electrical conductivity, and high level of density, which make it an ideal material for electrical and microelectronic applications. Spherical tungsten powder is used as a raw material in industries such as tungsten and tungsten alloy 3D printing, porous materials, and high-density powder spraying.
