?High-Quality Copper Clad Aluminum? This 18 AWG 100FT wire features Copper Clad Aluminum (CCA) construction, offering the same signal frequency and corrosion resistance as copper wire. CCA wire is lighter, more flexible, and provides excellent cost-efficiency, delivering the same performance as pure copper without the extra cost. ?Durable Weather-Resistant? Made with a high-quality PVC jacket, this wire is flame retardant, anti-aging, and resistant to acids, alkalis, and moisture. It is designed to withstand harsh environmental conditions, with an operating temperature range of -20C to 80C, making it perfect for automotive, outdoor, and other demanding applications. ?Flexible Easy to Use? This wire is easy to strip and cut to length, providing flexibility for different project needs. The red and black jacket colors make it simple to distinguish polarity, while the numbered markings ensure precise installation. Comes neatly wrapped on a hard plastic spool for convenient dispensing. ?Wide Application for Low Voltage Projects? Ideal for 12V/24V DC systems, this wire is versatile for use in automotive speakers, subwoofers, LED light strips, remote control cars, electronic devices, lighting, and DIY projects. It is a reliable choice for low-voltage electrical hookups in both home and automotive environments. ?Cost-Effective Reliable Performance? With Copper Clad Aluminum (CCA), you get the same high-quality signal transfer and durability as copper wire, but at a lower cost. Enjoy the same reliability and performance without breaking the bank, while benefiting from the lightweight and flexible nature of CCA wire for easy installation.
