Copper to aluminum bus bar connections.

Silver plated multipurpose 110 copper bars with rounded edges. Just as often however the connections fail even when people do follow the basic rules. 1 copper busbar is large load than aluminum busbar. Nevertheless aluminum is significantly lighter than copper.

The superior ampacity of electrical bus bars help achieve better thermal control in enclosed applications. 2 copper busbar is more flexible than aluminum wire. 3 copper busbar is lower resistivity. Aluminum and copper bus bar also improves the reliability of a power or electrical grounding connection by eliminating the need for a mechanical cable lug crimp.

So when correcting for weight aluminum is far more conductive than copper. Aluminum offers many possibilities including laminated bus and insulated bus bar connectors. As a result the once common plated copper bus bar is no longer what you re likely to encounter. A brief introduction to the advantages and disadvantages of copper busbar and aluminum wire.

Why in the early 70s the epa came down hard on plating facilities. Because aluminum has this imperfect surface and is also subject to thermal expansion and contraction which is 42 higher than copper there is a greater risk that.
