Material Properties:

Copper is a highly versatile material known for its excellent electrical and thermal conductivity, corrosion resistance, and machinability. Key properties of copper include:

• Electrical Conductivity: Ideal for electrical and electronic applications.

• Thermal Conductivity: Efficient heat dissipation, suitable for heat exchangers and cooling systems.

• Corrosion Resistance: Resists oxidation and environmental degradation.

• Machinability: Easy to machine with CNC processes, ensuring high precision and smooth finishes.

• Antimicrobial Properties: Naturally inhibits the growth of bacteria, making it suitable for medical and food processing applications.

Surface Treatment Options:

To further enhance the performance and appearance of our copper CNC machining parts, we offer various surface treatment options:

• Polishing: Polished copper parts have a smooth and shiny surface, which not only improves their aesthetic appeal but also reduces the risk of corrosion and dirt accumulation.

• Plating: We can apply different plating materials such as nickel, chrome, or gold on the copper surface. Plating can improve the corrosion resistance, wear resistance, and electrical properties of the parts.

• Anodizing: Although anodizing is more commonly associated with aluminum, special anodizing processes can be applied to copper to create a protective oxide layer on the surface.

Applications of Copper CNC Machining Parts:

1. Electrical and Electronics Industry

• Connectors and Terminals: Copper parts are used in electrical connectors, terminals, and switch components due to their high conductivity.

• Heat Sinks: CNC-machined copper heat sinks are used in electronic devices to dissipate heat efficiently.

2. Automotive Industry

• Sensors and Actuators: Copper parts are used in sensors, actuators, and wiring harnesses.

• Radiators and Cooling Systems: Copper's thermal conductivity makes it ideal for radiators and cooling system components.

3. Plumbing and HVAC

• Valves and Fittings: Brass and bronze fittings are commonly CNC-machined for plumbing systems.

• Heat Exchangers: Copper parts are used in heat exchangers and HVAC systems due to their thermal conductivity and corrosion resistance.
