Tungsten Alloy High-Temperature Nozzles – Extreme Environment Fluid Control Solutions

Why Tungsten Alloy?

Tungsten heavy alloys (WNiFe, WCu, WMo) are ideal for ultra-high-temperature nozzles due to:

Melting Point (3,422°C) – Withstands plasma arcs, rocket exhaust, and molten metal splashes.

Abrasion Resistance – 10X longer lifespan than steel in particle-laden flows (e.g., thermal spray, sandblasting).

Thermal Shock Stability – Minimal cracking under rapid heating/cooling cycles.

Corrosion Resistance – Performs in acidic, alkaline, and oxidizing environments.
