Aluminum (Al) is about two-thirds lighter in weight than copper (Cu), and this lightweight material can reduce the overall weight of cable harnesses. Even considering the relationship between conductivity and density, aluminum wire with the same resistance is still about 50% lighter than the same copper wire.

In addition to being lighter in weight, aluminum is also a widely available and easily obtainable conductive base material. Compared to other metals, copper has limited resources and belongs to the category of "investment oriented" metals. This means that the price of aluminum will be relatively stable and much lower than the price of copper, with good cost control.

From the perspective of installation cost, due to the relatively light weight of aluminum wires, there is no need for cable trays or conduits during the installation process, which can save a lot of installation materials and save 20% -50% of installation cost compared to copper wires.
