Copper Clad Aluminum High-Performance Composite
Approximately 58-63% weight reduction at equal dimensions, 62-70% IACS conductivity specification. Clad & Weld process forms a metallurgical bond at the Cu-Al interface.
RAYTRON is a specialized manufacturer of Copper Clad Aluminum (CCA) wire, produced to strict ASTM B566 standards. CCA bimetallic conductors specify 62% to 70% IACS conductivity (depending on copper cross-sectional area ratio and product form), with approximately 58-63% weight reduction at equal dimensions. System-level weight reduction depends on conductivity, conductor size, insulation, termination and application design. Engineered with a metallurgical bond; interface quality is inspected per the product control plan. Whether CCA is suitable as a replacement for copper requires application validation.

What is Raytron CCA?
Raytron CCA (Copper Clad Aluminum) is a bimetallic conductor available as round wire, flat wire, strip and foil. Typical conductivity ranges from 62-70% IACS depending on copper cross-sectional area ratio and product form. It is intended for applications where weight, cost and conductivity must be balanced, subject to termination, thermal-rise and corrosion validation.
Manufacturing Process
This product is manufactured using Clad & Weld process with metallurgical bonding. It is NOT electroplated.
Metallurgical bonding creates a permanent metallurgical connection, ensuring stable reliability compared to electroplating. This enables excellent weldability, designed to resist peeling during bending, and stable performance under thermal cycling conditions.

Engineering Inquiry Note: Aerospace / eVTOL / Robotics / Medical / Safety-critical wiring applications must be marked as "Engineering Inquiry / Project Validation Required" and must not be presented as ordinary applications.
CCA is not equivalent to pure copper: CCA conductivity (62-70% IACS) is lower than pure copper. Termination, thermal rise and long-term reliability must be validated for the specific application. ASTM B566 may apply to specific CCA wire categories. Final compliance depends on product form, copper ratio, diameter and purchase specification.
⚠️ Electrochemical Compatibility Notice
Copper Clad Aluminum (CCA) may experience galvanic corrosion in humid or salt spray environments when in direct contact with dissimilar metals (such as copper or steel). To ensure product lifespan, please note the following:
- • Avoid direct contact between CCA and pure copper or steel; use insulating spacers or coatings for isolation
- • In outdoor or high-humidity environments, tin-plated or silver-plated post-processing options are recommended
- • For grounding applications, please select Copper Clad Steel (CCS) for better corrosion resistance

Frequently Asked Questions
Learn more about CCA products
What are the advantages of CCA compared to pure copper?
Key characteristics: 1) Approximately 58-63% weight reduction at equal dimensions; 2) Conductivity specification 62-70% IACS (depending on copper cross-sectional area ratio and product form); 3) System-level weight reduction depends on conductivity, conductor size, insulation, termination and application design; 4) Whether CCA is a suitable replacement for copper requires application validation. Cost comparison is indicative, depending on copper price, dimensions and order volume.
What conductivity can CCA achieve?
Depending on specifications, CCA conductivity ranges from 62-70% IACS. Copper layer ratio can be optimized for different application requirements.
What is the service life of CCA products?
Service life depends on the operating environment, termination method, coating, insulation and application validation. CCA can provide long-term reliability in validated applications, but it should not be treated as a universal direct replacement for copper. Our Clad & Weld process forms a metallurgical bond at the copper-aluminum interface; interface quality is inspected per the product control plan. Actual service life must be validated for the target application.
Can custom specifications be made?
Yes, we can customize various specifications including different wire diameters, copper layer ratios, and insulation requirements. MOQ can be negotiated based on specifications.
Which applications are suitable for CCA?
CCA is most suitable for selected cable, RF, communication, speaker, lightweight harness, motor winding and composite PV ribbon evaluation projects. Visit our CCA Application Guide for detailed suitability, risks and validation requirements.
