W-Cu Series en Mecanizado CNC
Tungsten-Copper (W-Cu) alloys have a balance of high thermal conductivity, wear resistance, and electrical conductivity.
Comprising tungsten as the primary component and copper as the secondary, typical compositions range from 70% W / 30% Cu to 90% W / 10% Cu.These alloys are commonly used in electronic packaging, aerospace components, and CNC-machined parts. When machining W-Cu, careful considerations are required.
We use proper tooling, such as carbide or PCD inserts, and cutting fluids to manage heat. We optimize machining parameters, and post-machining processes like grinding may be applied for specific surface finishes. Precision and quality control are important; DEK has experienced machinists familiar with W-Cu alloys' unique characteristics. Additionally, we observe safety precautions when machining due to potential health hazards associated with tungsten dust and fumes during machining.

Conocimientos básicos of W-Cu Series (ASTM)
What is W-Cu Series (ASTM)?
The Tungsten (W)–Copper (Cu) series refers to composite materials that combine tungsten and copper. Tungsten is known for its high melting point, great thermal and electrical conductivity, and strong mechanical properties, while copper has high thermal and electrical conductivity. By combining these materials, engineers create composites with unique properties suitable for applications needing a mix of high thermal and electrical conductivity along with mechanical strength.
Common uses include electronic packaging, aerospace components like rocket nozzles, and defense applications. Tungsten–Copper alloys find a place in high-temperature environments and are used for resistance welding electrodes, where a balance of strength and conductivity is important. The specific composition varies based on the desired properties for different applications, allowing customization for optimal performance.
