Characteristics of Pure Tungsten Machining
Pure tungsten is one of the most important materials used in tungsten CNC machining for semiconductor and high-temperature industrial applications. It has the highest melting point of all metals (3422°C), outstanding thermal stability, and excellent resistance to high-temperature deformation.
Because tungsten exhibits extremely high hardness and brittleness at room temperature, machining pure tungsten parts requires specialized cutting parameters and tooling strategies. Improper machining can easily cause edge chipping, micro-cracks, or dimensional instability.
With extensive experience in refractory metal machining, our team utilizes optimized cutting parameters, dedicated fixtures, and stable CNC processes to minimize cracking risks and ensure consistent machining quality for high-value tungsten components used in semiconductor equipment and high-temperature systems.
