Aluminum wire offers distinct advantages over copper wire, particularly in terms of cost. With a density of 2.7 g/cm³ compared to copper's 8.9 g/cm³, aluminum is significantly lighter. When the conductor size is the same, copper weighs about three times more than aluminum. However, aluminum’s electrical conductivity is roughly 60% that of copper, which means it requires a larger cross-sectional area to carry the same amount of current. As a result, if both wires have the same current-carrying capacity, copper wire will weigh approximately twice as much as aluminum. Considering the price difference—copper is roughly seven times more expensive than aluminum—the overall cost of an equivalent copper wire remains much higher.
It's also important to note that because aluminum conductors are larger in cross-section, they require more insulation and protective materials, which can reduce their cost advantage. Today, aluminum alloy cables are typically priced at around 75% of copper core cables. Additionally, when it comes to installation, aluminum wires are lighter, so they don't always need additional supports like bridges or conduits, leading to savings of 20% to 50% in installation costs.
Given the cost benefits of aluminum and the limited availability of copper resources in China, many companies in the industry have invested heavily in research and development. Over the past few years, China's aluminum alloy cable sector has made significant progress in upgrading low-voltage cable technology and replacing older products. As the technology continues to mature and market acceptance grows, the scale of "aluminum-based copper" solutions is expected to expand rapidly in the coming years. This shift not only helps reduce material costs but also supports sustainable development by making better use of available resources.
