Electrical Applications of Aluminum

The incorporation of aluminum in electrical and thermal applications is driven by the excellent electrical and thermal conductivities of its alloys, primarily from the 1xxx series (for electrical) and the 3xxx, 5xxx, and 6xxx series (for thermal). Additionally, the inherent advantages of aluminum, such as its lightweight nature, favorable strength-to-weight ratio, and robust corrosion resistance, further contribute to its suitability in these applications when compared to alternative materials.

While aluminum’s volume thermal conductivity may be lower than that of copper, the extrudability of aluminum enables versatile design possibilities for aluminum profiles. This versatility allows for the cost-effective production of configurations well-suited for efficient heat dissipation. Moreover, extruded sections can undergo color anodization to enhance the emission capacity of radiating surfaces. The combination of these attributes makes aluminum a preferred choice in electrical and thermal applications, ensuring optimal performance and durability.
