Why Choose Copper for CNC Machining?
Copper is a highly conductive and corrosion-resistant metal, making it ideal for parts that require excellent electrical or thermal performance. Despite its softness, copper’s unique properties make it essential in modern technology and engineering systems.
- High Electrical Conductivity: Ideal for electrical contacts and connectors
- Thermal Conductivity: Perfect for heat sinks and cooling systems
- Corrosion Resistance: Performs well in industrial and humid environments
- Ductility: Easily forms complex shapes through CNC milling or turning
- Non-Magnetic: Useful for sensitive electronic and medical applications
