CuNi23 Wire 0.23mm

CuNi23 Wire (0.23 mm Diameter) – Overview and Specifications

Material Composition:

• Alloy: Copper-Nickel

• Composition: Approximately 77% Copper and 23% Nickel

• Designation: Commonly referred to as CuNi23

Physical Properties:

• Diameter: 0.23 mm

• Wire Gauge: Typically falls around a very fine gauge (comparable to ~31–32 AWG)

• Density: ~8.9 g/cm³ (close to that of copper and nickel)

• Electrical Resistivity: Approximately 0.65–0.70 μΩ·m (varies slightly with exact composition)

Mechanical & Chemical Properties:

• Ductility: Excellent, allowing it to be drawn into fine, consistent wires

• Tensile Strength: Sufficient for applications requiring both flexibility and durability

• Corrosion Resistance: Superior, particularly in marine and saltwater environments

• Oxidation Resistance: Enhanced by the nickel content, reducing degradation over time

Key Advantages:

• High Corrosion Resistance: Ideal for harsh environments, especially where exposure to seawater or chemicals is expected

• Balanced Conductivity and Strength: Provides good electrical conductivity along with mechanical resilience

• Versatility: Suitable for both electrical and structural applications in fine wire form

Common Applications:

• Marine Industry: Used in condenser tubing, heat exchangers, and wiring exposed to marine environments

• Electrical and Instrumentation: Employed in precision components and sensors where corrosion resistance is critical

• Specialized Wiring: Suitable for applications requiring fine, durable, and corrosion-resistant wire, including decorative and functional purposes
