What is one reason for the popularity of aluminum busbars?

One reason for the popularity of aluminum busbars is that aluminum is cheaper and more readily available compared to other materials like copper. This cost-effectiveness makes aluminum an attractive choice for many applications in electrical systems, particularly where large quantities are required. Additionally, aluminum's lightweight nature makes it easier to handle and install, leading to further savings on labor and transportation costs.

While other properties such as conductivity, ruggedness, and temperature resistance are important considerations in the selection of materials for busbars, the economic factors associated with aluminum’s availability and pricing drive a significant portion of its use in the industry.
