Material & Conductivity: The Science Behind Our Copper Parts

We source only the highest-grade pure copper to ensure our parts deliver maximum performance:

- Copper Purity: Our T2 copper has a minimum purity of 99.95%, ensuring the highest possible electrical and thermal conductivity, free from impurities that could reduce performance

​

- Electrical Conductivity Testing: Every batch is tested for conductivity, with results consistently meeting or exceeding 58 MS/m, making our parts ideal for applications where low resistance is critical

​

- Thermal Performance: With thermal conductivity of 401 W/(m·K), our copper parts outperform most other metals in heat transfer, ensuring efficient cooling in high-power systems

​

- Material Stability: Pure copper maintains its mechanical and conductive properties even under temperature fluctuations, ensuring long-term performance without degradation

Advanced Surface Treatment & Finishing Processes

Our surface treatment processes are designed to enhance both performance and durability:

1. Deburring & Edge Finishing: All parts undergo precision deburring, either manually or via automated processes, to remove sharp edges and burrs that could affect assembly or performance

​

2. Anti-Oxidation Passivation: A chemical treatment that forms a thin, protective layer on the copper surface, preventing tarnishing and oxidation without impacting conductivity

​

3. Electroplating Services:

​

- Tin plating: Improves solderability and corrosion resistance for electrical contacts

​

- Nickel plating: Adds wear resistance and barrier protection for harsh environments

​

- Silver plating: Enhances high-frequency conductivity for RF applications

​

- Gold plating: Provides ultra-low contact resistance and long-term stability for critical components

​

4. Polishing & Buffing: Mechanical polishing to achieve smooth, reflective surfaces, ideal for applications requiring both performance and aesthetic appeal

Rigorous Quality Control & Inspection

Quality is at the heart of our production process, with multiple inspection stages:

- Raw Material Inspection: All incoming copper stock is tested for purity, hardness, and composition to ensure it meets our standards

​

- In-Process Quality Checks: Our machinists perform dimensional checks at key stages of production to catch errors early

​

- Final Inspection: Every part is inspected using coordinate measuring machines (CMM), optical comparators, and surface roughness testers to verify dimensions, tolerance, and surface finish

​

- Certifications & Documentation: We provide full inspection reports, material certificates, and compliance documents for all orders, including RoHS, REACH, and ISO 9001 certifications
