CCAM Wire (Copper-Clad Aluminum Magnesium Wire)
1. Common CCAM Wire Diameters & Reel Sizes
| Wire Diameter | Common Applications | Typical Reel Size | Reel Capacity |
|---|---|---|---|
| 0.12 mm | Braided shielding (coaxial, LAN, HDMI, USB) | ABS φ200–250 mm | 2–5 kg (fine wire) |
| 0.18 mm | Braiding, flexible stranded wires (e.g., 16×0.18mm) | ABS φ250 mm | 5–10 kg |
| 0.20 mm | Stranded cores (7×0.20mm, 16×0.20mm), speaker/audio wire | ABS φ250 mm | 5–10 kg (bulk use) |
2. Key Features
Structure: Aluminum-magnesium alloy core with an outer copper layer
Improved Strength: Higher tensile strength than standard CCA wire
Lightweight: Lighter than pure copper; suitable for weight-sensitive applications
Conductivity: Around 55%–65% IACS, depending on copper layer thickness
Enhanced Flexibility: Suitable for fine-stranded and flexible cables
Good Solderability: Copper surface allows standard soldering techniques
3. Applications
High-performance LAN/network cables (CAT6, CAT6A)
HDMI, USB, and data transmission cables
Audio and speaker cables
Automotive and mobile device wiring
Coaxial cable inner conductors
4. Advantages over CCA
Better tensile strength and anti-fatigue performance
More reliable in applications with frequent movement or bending
Improved performance in automated high-speed production environments

| Corrosion Resistance | ★★☆ (Good, copper clad) | ★★ (Moderate) | ★★☆ (Better than CCA) | ★★★ (Excellent) |
| Cost | ★☆ (Low-Mid) | ★★ (Low) | ★★☆ (Mid) | ★★☆ (Low-Mid) |
| Common Uses | Coaxial core, grounding, telecom drop lines | LAN, coaxial, speaker wire | HDMI, USB, flexible LAN | Braided shielding, overhead cables |
6. Quick Summary
1.CCS: Best for strength and anti-theft; suitable for coaxial cable cores and grounding wires; poor flexibility and low conductivity.
2.CCA: Economical for LAN, coaxial, and speaker wires; moderate performance, low weight.
3.CCAM: Balanced option with better strength and flexibility than CCA; ideal for high-flex applications like HDMI/USB.
4.Al-Mg: Best weight-to-strength ratio; widely used in braided shielding and aerial cables; not solderable.
