Description

Quick Detail:

C18080 (UNS C18080), also designated as CuCrAgFeTiSi, is a high-performance, heat-treatable copper-chromium-silver alloy engineered to deliver an exceptional balance of high strength, superior electrical conductivity, and excellent stress relaxation resistance at elevated temperatures. It is widely recognized as a premium material for high-current and high-reliability electrical applications.

Key Characteristics & Advantages:

1. High Electrical Conductivity: Electrical conductivity: ≥75–80% IACS at room temperature

2. High Mechanical Strength: ensile strength: 480 MPa+ (depending on temper/condition), Excellent hardness and fatigue resistance

3. Superior Stress Relaxation Resistance: Exceptional resistance to stress relaxation up to 200 °C

4. Excellent Thermal Conductivity Thermal conductivity: ~185 Btu/(ft·hr·°F) (~320 W/(m·K)), Efficient heat dissipation makes it ideal for heat sinks, power module bases, and high-power device packages.

5. Good Formability & Platability: Excellent cold formability and drawing capability — well-suited for fine wire, precision stamping, and deep-drawn components.

6. Corrosion & Oxidation Resistance: Good resistance to atmospheric corrosion and oxidation at moderate elevated temperatures, Maintains stable long-term performance in harsh industrial and automotive environments.
