CNC Machining in Pure Tungsten

Pure Tungsten is an ultra-high-density refractory metal designed for extreme temperature and high-energy environments. InstaVoxel provides precision CNC machining solutions for Tungsten components where thermal stability, mass density, and structural integrity are mission-critical.

Advantages of Pure Tungsten

Pure Tungsten (W) has the highest melting point of any metal and maintains exceptional strength at elevated temperatures. These properties make it indispensable in aerospace, semiconductor, defense, and high-temperature industrial systems.

Key Features
Extremely high melting point (> 3,400 °C)
Very high density (≈ 19.3 g/cm³)
Excellent thermal stability at extreme temperatures
Low vapor pressure for vacuum applications
