Core Copper Conductive Products
Our product range covers three main categories of copper conductive components, each designed for specific industrial applications:
1. Precision Stamped Copper Conductive Sheets
Our flagship stamped copper products feature one-piece construction with no welding or joints, ensuring maximum conductivity and structural integrity. These components typically include:
- Copper shovels with reinforced edges for industrial equipment
- Copper connection plates with precise hole patterns for electrical assemblies
- Custom-shaped copper contacts for switchgear applications
The stamping process allows for high-volume production while maintaining ±0.05mm tolerance on critical dimensions. We can process various copper alloys including brass, phosphor bronze, and beryllium copper depending on the application requirements.
2. CNC Machined Copper Conductive Parts
For applications requiring more complex geometries or tighter tolerances, our CNC machining capabilities deliver exceptional results. Typical products include:
- Copper connecting rods with precise dimensions for automotive electrical systems
- Custom copper bushings with knurled surfaces for enhanced grip
- High-precision copper terminals for power distribution equipment
Our CNC machines achieve positional accuracy of ±0.01mm and surface roughness below Ra0.8μm. We can machine copper parts up to 300mm in length with complex features including threads, slots, and contours in a single operation.
3. Non-Standard Custom Copper Components
Understanding that each application has unique requirements, we offer complete customization services for copper conductive parts. This includes:
- Material selection from pure copper to various alloys
- Dimensional customization beyond standard sizes
- Special surface treatments like tin plating, nickel plating, or passivation
- Heat treatment processes to improve mechanical properties
Our engineering team works closely with clients during the design phase to optimize component geometry for both performance and manufacturability, helping reduce production costs while maintaining functionality.

Our engineering team provides free DFM (Design for Manufacturing) analysis to help optimize component design for both performance and cost before production begins.
FAQ
What types of copper materials do you use for conductive sheets?
We work with various copper materials depending on application requirements: pure copper (C11000) for maximum conductivity, brass (C26000) for better strength, phosphor bronze (C52100) for wear resistance, and beryllium copper (C17200) for high-stress applications. Our material selection process considers conductivity, mechanical properties, and cost to recommend the optimal solution for each project.
How do you ensure dimensional accuracy in copper conductive components?
We implement multiple quality control measures: using high-precision CNC equipment (±0.01mm accuracy), performing first-article inspection before mass production, conducting in-process sampling checks, and performing 100% final inspection. Our CMM (Coordinate Measuring Machine) verifies critical dimensions against CAD models to ensure all parts meet specifications.
Can you provide surface treatments for copper conductive parts?
Yes, we offer various surface treatments to enhance performance: tin plating for solderability, nickel plating for corrosion resistance, silver plating for high-conductivity applications, and passivation for oxidation protection. We can also provide custom plating thickness requirements and select the most appropriate process based on the component’s operating environment.
What is your minimum order quantity for custom copper components?
We accommodate both small and large orders: prototyping and small-batch production starting from 100 pieces, with no strict MOQ for standard products. For custom components, we recommend initial orders of 500-1,000 pieces to optimize production efficiency and cost, but we can adjust based on specific project requirements and component complexity.
How do you handle confidentiality for custom designs?
We take customer intellectual property very seriously. All custom designs are protected under strict NDA (Non-Disclosure Agreement) terms. Our production facilities implement secure document control systems, and access to custom design files is restricted to authorized personnel only. We’ve successfully completed projects for multiple Fortune 500 companies with these confidentiality measures in place.
