Copper
We can fulfill complex orders for prototypes and low-volume production runs in a wide variety of post-processing and surface finish options. Work with us to access our vast CNC copper machining supply chain today.
We offer a complete copper CNC machining service and can produce complex copper parts.
Copper parts are corrosion-resistant and versatile and can be used for applications requiring electrical conductivity and higher-quality aesthetics.
When creating Copper parts with us, you can apply up to 7 different surface finishing options.
Strengths
- Functional Properties: Copper has top-tier thermal and electrical conductivity among metals. It's also corrosion-resistant, making it suitable for demanding environments like radiators and automotive circuits.
- Processing Advantages: Copper is easy to shape in both cold and hot states. It can be used to make complex parts like gears and bearings, balancing functionality and aesthetics.
- Flexible Surface Treatment: Copper supports processes like plating and polishing. This not only enhances surface smoothness but also boosts wear and corrosion resistance.
Weaknesses
- Some copper alloys are difficult to weld. Issues like hot cracking and oxidation can occur during welding, so it's important to ensure material compatibility with the technique.
- Corrosion resistance varies with alloy composition. For example, aluminum bronze performs well in seawater, while brass may corrode easily in ammonia environments. Parts may have a shorter lifespan in highly acidic or alkaline conditions.
Applications
- Electronics: High thermal conductivity copper (C101) is used in mobile phone motherboard heat sinks and Type-C connectors.
- Automotive: Copper alloys are used in electric vehicle battery connection sheets and turbocharger bearings (wear-resistant tin bronze).
- Energy: Copper alloys are found in wind power converter conductive rings and nuclear power plant valve seals (radiation-resistant copper alloys).
- Automation: High-strength beryllium copper is used in injection molding machine hot runner nozzles and compressor valve plates.
