Aluminum alloy wire, aluminum alloy strand wire, covered electrical wire, and terminal-equipped electrical wire

An aluminum alloy wire composed of an aluminum alloy, wherein

• the aluminum alloy contains more than or equal to 0.03 mass % and less than or equal to 1.5 mass % of Mg, more than or equal to 0.02 mass % and less than or equal to 2.0 mass % of Si, more than or equal to 0 mass % and less than or equal to 0.5 mass % of one or more elements selected from Fe, Cu, Mn, Ni, Zr, Cr, Zn, and Ga and more than or equal to 0 mass % and less than or equal to 1.0 mass % of the one or more elements being contained in total, and a remainder of Al and an inevitable impurity, Mg/Si being more than or equal to 0.5 and less than or equal to 3.5 in mass ratio, and
• the aluminum alloy wire has a dynamic friction coefficient of less than or equal to 0.8.
