2 AWG Bare Aluminum, Tinned, Solid, 410'

Bare aluminum is aluminum in its rawest form, lacking any protective coating or surface treatment. While it develops a natural, protective oxide layer upon exposure to air, this layer is thin and transparent. It is used in applications where conductivity and corrosion resistance are needed, such as overhead electrical transmission lines, but it is more susceptible to scratches and dullness compared to treated aluminum.
