Primary Wire

Lightweight, resilient, and efficient CCS and CCA

Optimized for your needs

Copperweld’s suite of CCS and CCA primary wire provides engineers with a better alternative to optimize vehicle electrical architectures.

Whether carrying a load to drive a window motor or sending low energy signals to a lighting module our suite of CCA and CCS wire can be selected per the application to provide the perfect balance of weight, strength, current capacities and cost.

Our wire is available in both SAE and ISO wire sizes, bare or insulated in PVC or XLPE. Common CCS diameters of 0.13mm² (26 AWG) to 0.50mm² (20 AWG), offered as annealed or hard-drawn and 40% conductivity.  CCA wire is commonly available in 0.50mm² (20 AWG) to 8mm² (8 AWG) diameters, offered as annealed or hard-drawn, with 10% and 15% copper volumes.  Copperweld offers a wide variety of reel sizes, materials and options.

Copperweld Automotive Benefits

Strength & Resiliency

Copperweld CCS's high-carbon steel core provides strength, flexibility and the ability to stretch more than 15% — perfect for applications subject to repetitive motion.

Lightweight

The linear weight of our CCS is more than 10% lighter than solid copper which can help lower overall vehicle weight, save on freight expenses and improve the ease of installation.

Connectivity

Copperweld CCA provides the weight savings achievable with aluminum wiring while offering the added convenience of standard copper connection sytems.

Energy Efficient

Equivalently sized Copperweld CCA provides a larger cross-sectional area, resulting in overall operating temperatures, which can improve long-term reliability.

Corrosion Resistance

Appropriately insulated Copperweld CCS is perfectly suited for severe environmental conditions involving salt, water and typical under-hood contaminants.

Theft Deterrent

Reduce costly in-factory wire theft. Copperweld’s metallurgically bonded conductors have extremely low street value, making it unattractive to copper thieves.
