Description of Spherical Tungsten Molybdenum Alloy W-Mo Powder
Spherical tungsten-molybdenum (W-Mo) alloy powder combines tungsten and molybdenum to offer exceptional high-temperature strength, thermal conductivity, and resistance to thermal shock. Produced typically through gas atomization, the powder consists of spherical particles that enhance flowability and packing density, making it ideal for additive manufacturing and powder metallurgy. The alloy’s high melting point and stability at elevated temperatures make it suitable for applications in aerospace, electronics, and high-temperature industrial processes. Additionally, it exhibits excellent resistance to wear and corrosion, ensuring long-lasting performance in demanding environments. Its properties make W-Mo powder particularly valuable for producing components that operate under extreme conditions.

Preparation of ultrafine tungsten-molybdenum composite powder and its sintering behavior
- In this paper, a new method for preparing ultrafine tungsten-molybdenum composite powders has been proposed. The carbothermic pre-reduction of the mixture of molybdenum trioxide and tungsten trioxide with insufficient carbon black under argon atmosphere was carried out, to generate the pre-reduced tungsten-molybdenum composite powder containing a small amount of residual dioxide. Thereafter, the obtained reaction product was subjected to hydrogen reduction to remove the residual dioxide and generate pure tungsten-molybdenum composite powder with the particle size of 100–200 nm. Two kinds of ultrafine tungsten-molybdenum alloy powders (Mo-30 wt% W, Mo-70 wt% W) were prepared.
