Aluminum is a lightweight and electrically conductive metal, and round polyurethane enameled aluminum wire for automobiles uses aluminum conductors, which are lighter than copper conductor wires. Although aluminum has a relatively low electrical conductivity, sufficient electrical conductivity can be achieved by optimizing the design and materials.

The conductor surface of round polyurethane enameled aluminum wire for automotive applications is covered with a polyurethane enameled insulating layer. This insulation provides good electrical insulation and stops current leakage between the conductors and between the conductors and their surroundings. The polyurethane enameled insulation also has a certain temperature resistance and is able to maintain stable electrical properties within a certain temperature range.

Round polyurethane enameled aluminum wires for automotive applications typically have good corrosion resistance and are able to resist corrosion of the wires from factors such as chemicals and humidity in the automotive environment. This enables them to provide reliable electrical connections in automotive electrical systems and have a long service life.


Round polyurethane enameled aluminum wires for automotive use are specially designed to withstand factors such as vibration, temperature changes and mechanical stress in the automotive environment. They are usually flexible and have a certain tensile strength to withstand vibrations and shocks during automobile operation.

Round polyurethane enameled aluminum wire for automobiles is mainly used for low-voltage circuits in automotive electrical systems, such as lighting systems, instrument panels, audio systems, power windows and door lock systems. When using automotive round polyurethane enameled aluminum wire, you need to follow the electrical specifications and guidelines provided by the automotive manufacturer to ensure proper installation and use.

It is important to note that aluminum conductors used in automotive electrical systems need to be compatible with other components and connectors and follow proper design and installation requirements due to the different electrical conductivity and mechanical properties of aluminum and copper conductors. It is also important to regularly inspect and maintain electrical system connections to ensure safety and reliability.
