product detail
Tungsten powder is a fine metallic powder made from tungsten (W), known for its exceptional properties, including the highest melting point of all metals, high density, and excellent strength at elevated temperatures. Key Properties High melting point: 3422°C (6192°F) High density: ~19.25 g/cm³ (similar to gold) Excellent strength & hardness (even at high temperatures) Good electrical & thermal conductivity Corrosion resistance(resistant to acids and alkalis) Production Methods 1. Hydrogen Reduction: - Tungsten oxide (WO₃ or WO₂) is reduced in a hydrogen atmosphere. - Reaction: [ WO_3 + 3H_2 rightarrow W + 3H_2O ] 2. Carbon Reduction(less common due to carbide formation). 3. Mechanical Alloying (for ultrafine or nano-sized powders). 1. Hardmetal/Cemented Carbides (WC-Co for cutting tools, drills). 2. Electronics (filaments, electrodes, semiconductors). 3. Military & Aerospace (armor-piercing projectiles, rocket nozzles). 4. Additive Manufacturing (3D Printing) for high-performance parts. 5.Radiation Shielding (X-ray & gamma-ray protection).
