10% by volume copper clad aluminum magnet wire for sale  is widely used for hard disk drive coils, audio speaker coils with heat resistant enamels and high strength bond coats, which is a conductive wire with a 10% copper cladding over aluminum conductor and insulation coating.

Copper clad aluminum magnet wire also called CCAW copper coated aluminum wire.

What is copper-clad aluminum wire?
Copper Clad Aluminum (CCA) is a clad bi-metal utilizing electrical conductor grade aluminum as its core and oxygen free copper for its outer layer, so it’s naturally lighter than solid copper wire. The cladding process creates a permanent continuous weld between the two metals. The lightweight properties of copper-clad aluminum wire make it easy to install. With its wide range of supported applications, copper-clad aluminum wire is versatile. The "10% by volume" specification refers to the proportion of copper in the wire's cross-sectional area.

In CCA magnet wire, the aluminum core provides the structural support, while the copper coating enhances its electrical conductivity. The 10% by volume indicates that approximately 10% of the wire's cross-sectional area is occupied by the copper layer, while the remaining 90% is composed of aluminum.

This type of wire offers a balance between cost and performance. Copper is an excellent conductor of electricity, but it is also more expensive than aluminum. By using CCA wire with a 10% copper volume, manufacturers can achieve good electrical conductivity while reducing costs compared to solid copper wire.

It's worth noting that the electrical properties of CCA wire, such as resistance and current-carrying capacity, may differ from those of pure copper wire. Therefore, it's important to consider these factors when selecting the appropriate wire for a specific application.
