Copper Clad Aluminum Ribbon Wire

RAYTRON Copper Clad Aluminum Ribbon Wire is manufactured using the Clad & Weld process with a metallurgically bonded copper-aluminum interface. Conductivity depends on the copper ratio and purchase specification; confirm the applicable grade and measured values per lot in your RFQ. Calculated by rule of mixtures, composite density is about 3.3–3.6 g/cm³ at 10–15% copper by volume (calculated, not measured), giving lower weight than copper at equal geometry. Suitable for precision electronic components, sensors, miniature motors and high-fidelity speaker voice coils, with dimensional tolerance of ±0.003mm; safety-critical uses require project-level evaluation and customer-led validation. Ribbon wire uses project-specific specifications and agreed test methods.
