Product Description

Product Description

  

Tinned CCA (Copper-Clad Aluminum) Wire

Description:
Tinned CCA Wire is a high-performance composite conductor consisting of an aluminum core cladded with a copper layer and coated with a thin tin plating. This hybrid design combines the lightweight and cost-effectiveness of aluminum with the conductivity and corrosion resistance of copper, enhanced further by the tinning process for superior solderability and environmental durability.

Structure:

• Core: High-purity aluminum (AA-1350 or equivalent)
• Cladding: Oxygen-free copper layer (≥10% conductivity contribution)
• Coating: Electroplated tin (2-5 μm thickness, customizable)

Key Features:

1. Enhanced Conductivity:

   • Conductivity: 20-30% IACS (compared to pure copper)
   • Tin coating reduces surface oxidation, ensuring stable electrical performance.

2. Lightweight & Cost-Efficient:

   • 40-50% lighter than pure copper wire, ideal for weight-sensitive applications.
   • Lower material cost while maintaining functional performance.

3. Corrosion Resistance:

   • Tin layer protects against moisture, salt spray, and sulfurization (IEC 60068-2-11 compliant).

4. Mechanical Flexibility:

   • Tensile strength: 150-400 MPa (adjustable via annealing treatments).
   • Elongation: 10-25% (soft temper), suitable for repetitive bending.

Key Notes:

1. Customization:

   • Adjustable copper cladding ratio (10%-40%).
   • Optional tin coating grades (H0: 0-2 μm; H3: 5-8 μm).
   • Special insulation: PVC, XLPE, or FEP available for stranded wire.

2. Packaging:

   • Single wire: 5-50 kg spools (wooden/plastic reels).
   • Stranded wire: 500-2000 m/steel reel (waterproof wrapping).

3. Advantages:

   • Cost-effective: 30-50% lighter and cheaper than pure copper.
   • Corrosion resistance: Tin layer protects against oxidation and sulfurization.
   • Flexibility: Stranded wire suits dynamic applications (e.g., robotics, vehicles).

4. Limitations:

   • Not recommended for high-current (>1000 A) or high-temperature (>150°C) environments.
   • Lower tensile strength compared to copper-clad steel (CCS).
