Made from C1100 pure copper or brass (C2680), featuring the industry’s highest electrical conductivity (100% IACS). Outstanding EMI/RF shielding effectiveness, ideal for high-performance millimeter-wave, 5G communications, and RF shielding applications. Easy to process into complex shapes.
| Performance Metric | Pure Copper (C1100) | Brass (C2680) | Description |
|---|---|---|---|
| Composition | Cu >99.9% | Cu 70%, Zn 30% | Pure copper has high purity, brass is a copper-zinc alloy |
| Electrical Conductivity | 100% IACS | ~27% IACS | Pure copper is highest, brass is moderate |
| Shielding Effectiveness | 50-70 dB (1GHz) | 40-60 dB (1GHz) | Pure copper is optimal, suitable for RF/millimeter-wave |
| Density | 8.96 g/cm³ | 8.5 g/cm³ | Both are heavy, size and cost need consideration |
| Tensile Strength | 200-300 MPa | 300-400 MPa | Brass is stronger and harder, suitable for springs |
| Weldability | Excellent (Grade A) | Excellent (Grade A) | Both weld easily, welding temperature 800°C+ |
| Corrosion Resistance | Moderate (Grade B) | Good (Grade B+) | Brass is slightly better, zinc content helps |
| Relative Cost | 5.0x (Highest) | 2.5x (Moderate) | Pure copper has highest cost, brass offers better value |
| Machinability | Easy, soft | Moderate, slightly harder | Pure copper cuts easily, brass requires stronger tools |
| Common Thickness | 0.10-0.20 mm | 0.15-0.25 mm | Pure copper can be thinner, brass slightly thicker |
