Fine Gauge 0.10mm Silver-Plated Copper Wire for Precision Electronic Components
Product Description
Silver-Plated Copper Wire (0.10mm Diameter)
Product Overview
Silver-plated copper wire (0.10mm diameter) from Tankii Alloy Material is a high-performance fine conductor composed of a high-purity oxygen-free copper (OFC) core and a uniform, dense silver plating layer. Manufactured through precision drawing and continuous electroplating processes, this 0.10mm wire delivers excellent electrical conductivity, superior oxidation resistance, and reliable solderability. With a diameter tolerance of ±0.003mm and plating thickness of 0.5–3.0μm, it is widely used in high-frequency signal transmission, miniaturized electronic components, and aerospace wiring applications.
Standard Designations & Core Material Foundation
- Base Material: High-purity oxygen-free copper (OFC, ≥99.99%)
- Plating Material: 99.9% pure silver
- Key Specification: 0.10mm diameter (tolerance ±0.003mm)
- Plating Thickness: 0.5–3.0μm (customizable)
- Compliant Standards: ASTM B500, GB/T 4910, IEC 60884
- Manufacturer: Tankii Alloy Material, certified to ISO 9001 and IATF 16949
Key Core Advantages (Centered on 0.10mm & Silver Plating)
1. High Conductivity & Signal Integrity
- Enhanced Conductivity: Silver’s conductivity (63×10⁶ S/m) is higher than copper, reducing signal loss in high-frequency applications. The 0.10mm diameter balances conductivity and flexibility, making it ideal for high-speed data lines.
- Low Contact Resistance: The silver plating ensures stable, low-resistance connections in connectors and switches, even after repeated mating cycles.
2. Excellent Oxidation & Corrosion Resistance
- Silver Protective Layer: The dense silver coating prevents copper oxidation at high temperatures or in humid environments, maintaining long-term conductivity stability.
- Corrosion Resistance: Resists sulfurization and most chemical corrosion, suitable for harsh environments such as aerospace and industrial control systems.
3. Good Mechanical Properties & Processability
- Ductility & Flexibility: Elongation ≥15% (annealed) allows bending and winding on small mandrels (≥0.2mm) without breaking, suitable for fine-pitch components.
- Uniform Plating: Advanced electroplating technology ensures a smooth, consistent silver layer with no peeling or blistering, even after drawing and annealing.
