Products Description
Our Stamped Copper Terminal is the backbone of modern electrical systems, featuring:
Material Purity: 99.9% red copper (Cu≥99.9%) ensures ultra-high conductivity (≥99% IACS) and low contact resistance (≤5mΩ), ideal for minimizing energy loss in high-current circuits.
Stamping Excellence: Cold-stamped from premium T2 copper sheets, achieving dimensional accuracy ±0.02mm and mechanical strength (tensile strength ≥200MPa) for vibration-resistant connections.
Design Flexibility: Customizable for complex geometries (L-shaped, U-shaped, flanged terminals) via multi-stage stamping, supporting both standard (e.g., 6.3mm quick-connect) and proprietary designs for relay and switch manufacturers.
Key Advantages
1. Red Copper Performance for Electrical Excellence
99% IACS Conductivity: Matches silver's electrical efficiency at a fraction of the cost, critical for 100A+ current transmission in fuses and battery connectors.
Stamping-Enhanced Durability: Cold-stamped grain structure increases fatigue resistance by 15%, passing 100,000+ insertion cycles (IEC 60664-1) without deformation-perfect for high-use switches like household circuit breakers.
