Main Advantages of TU2 Purple Copper Strip (Oxygen-Free Copper)
High Purity and Low Oxygen Content
The oxygen content of TU2 purple copper is controlled below 0.003%, with purity ≥ 99.95%. This reduces lattice defects and impurity interference during electronic transmission, ensuring stable signal transmission.
Excellent Electrical and Thermal Conductivity
Electrical Conductivity: Up to 101% IACS (International Annealed Copper Standard), suitable for high-current applications such as high-voltage wiring harnesses and charging gun conductors.
Thermal Conductivity: Approximately 398 W/(m·K), effectively reducing temperature rise in heat sinks and power transmission systems, improving system stability.
Good Processing Performance
Elongation: Can exceed 40%, suitable for precision wire drawing, stamping, and other cold processing, improving yield by 23% in the production of micro-connectors.
Tensile Strength: 200-230 MPa, resulting in lower breakage rates during processing.
Corrosion Resistance and Low-Temperature Adaptability
Resistant to salt spray corrosion (mass loss of only 0.02g/m² after 1000 hours), suitable for marine, chemical, and other harsh environments.
Maintains 18% elongation at -196°C, making it ideal for aerospace cryogenic fuel pipeline systems.
Application Fields: High-vacuum electronic device seals, cryogenic superconducting equipment connection components, precision instrument conductive elements.
