Busbars are typically made of conductive metals such as copper or aluminum. These materials are chosen due to their excellent electrical conductivity, mechanical strength, and relatively low cost. Copper is often preferred for its superior conductivity and thermal performance, while aluminum is favored in applications where weight and cost are significant considerations. In some cases, busbars may also be coated or plated with materials like tin or silver to enhance their conductivity and resistance to oxidation.

Copper vs aluminum-choose the correct material for your project

There is debate over whether aluminum or copper is more suitable for busbars, as both have been successfully used. In the past 50 years, busbars have evolved beyond traditional distribution, with recent innovations shifting demand from copper to aluminum. Despite some misconceptions about aluminum, both materials can meet requirements if manufactured and installed correctly.
