What’s the Difference Between Aluminum and Copper in Electrical Applications? (.PDF Download)

April 5, 2016

There are obviously materials property differences, such as capacitance, weight, and cost, between aluminum (Al) and copper (Cu) to consider for an electrical application. Al was more prevalent in the past for products such as bus bars, fuses, and breakers. Over time, some designers have changed components from Al to Cu. Today, due to cost stability and coating, some designers are switching back...
