Driven by rising international commodity prices, domestic copper prices have surged from below RMB 70,000/ton to over RMB 100,000/ton, marking a nearly 50% increase. This cost pressure is accelerating the adoption of "aluminum-for-copper" substitution, particularly in small and medium-sized charging station construction, where aluminum alloy cable usage has risen to 60%-70%. Copper prices are expected to remain volatile in 2026, posing ongoing challenges to factory cost management.
