Copper (Cu) is a non-ferrous metal with high electrical and thermal conductivity, excellent corrosion resistance, and easy machinability. With its ductility, durability, and good mechanical strength, copper is widely used in the electrical and electronics industry, mechanical engineering, piping systems, and interior decoration. Copper also has natural antimicrobial properties, enhancing durability and safety in medical and household applications.
Characteristics and Features:
Excellent Electrical and Thermal Conductivity: The highest among common metals.
Good Corrosion Resistance: Can withstand various environments.
High Ductility: Easily flattened into thin sheets and drawn into wires.
Moderate Strength and Hardness: Hardness can be increased by adding other elements (forming alloys such as brass and bronze).
Good Machinability: Easy to cut, mill, turn, and drill.
Good Weldability: Can be welded using various methods.
Aesthetics: Distinctive color and easy to polish.
Corresponding CNC Technologies:
CNC Milling: Very suitable for shaping complex parts, heat sinks, electrodes, and other conductive components from copper.
CNC Turning: Used for machining parts with rotational symmetry such as shafts, bushings, and electrical connectors.
CNC Drilling: Performs precise drilling of holes.
Wire EDM (Electrical Discharge Machining): Particularly useful for creating complex shapes and small grooves in copper, taking advantage of its electrical conductivity.
Applications:
Copper and its alloys are widely CNC machined in various industries:
Conclusion: Due to its excellent electrical and thermal conductivity and good machinability, copper is an important material in CNC machining, especially for electrical and thermal applications. However, the high ductility of pure copper can sometimes cause difficulties during machining, requiring sharp tools and appropriate cutting conditions.
