Between 2019 and 2024, the total global trade values of Copper and Aluminum both increased, although Copper grew faster and more strongly. Copper’s trade value rose from about USD 212 million to nearly USD 348 million, supported by a higher CAGR of 10.4%, while Aluminum increased from around USD 203 million to approximately USD 276 million with a CAGR of 6.4%. Copper reached both its lowest and highest levels at the beginning and end of the period, respectively, whereas Aluminum experienced its minimum in 2020 and peaked earlier, in 2022. Trend analysis shows that Copper followed mostly upward movements with moderate changes, while Aluminum displayed milder shifts with lower volatility. Overall, Copper showed conventional volatility, Aluminum remained more stable, and both markets moved closely together, reflecting a very good and positive correlation throughout the period.

Between 2019 and 2024, the trade ratios of Copper Wirerod to Copper and Aluminum Wirerod to Aluminum both increased gradually, showing broadly similar behavior despite clear differences in scale. The Copper Wirerod–to–Copper ratio rose from 6.0% in 2019 to about 6.4% in 2024, while the Aluminum Wirerod–to–Aluminum ratio increased from 1.4% to nearly 1.7% over the same period. For Copper, the lowest ratio was recorded in 2020 at 5.7%, followed by a steady recovery that culminated in the highest value in 2024. Aluminum, by comparison, started the period at its lowest level in 2019 and reached a peak of around 1.8% in 2023 before easing slightly in the final year. Trend analysis shows that both ratios followed a slight upward path throughout the initial, early middle, late middle, and closing periods, consistently accompanied by low volatility. As a result, overall fluctuations in both indicators are assessed as limited. In the final year, the Copper Wirerod–to–Copper ratio increased by 0.1 percentage point, a level that appears somewhat unexpected when viewed against earlier values. Meanwhile, the Aluminum Wirerod–to–Aluminum ratio declined by 0.1 percentage point in 2024, a movement that was fully in line with prior trends. Finally, correlation results suggest a moderate and positive relationship between the two ratios, indicating that they generally moved in the same direction during the period under review.

From 2019 to 2024, Copper Wirerod clearly played a stronger role in the global trade of the entire Copper value chain than Aluminum Wirerod did in the Aluminum value chain. In more years during this period, Copper Wirerod held a higher position, which shows that its overall importance was greater. As the chart indicates, this stronger position was not temporary, and Copper Wirerod consistently maintained its more important role over the past six years. On average, Copper Wirerod accounted for more than 6.0% of total global Copper trade, while Aluminum Wirerod represented only about 1.6% of total global Aluminum trade. This clear difference highlights the more effective role of Copper Wirerod in its value chain. Importantly, the relative positions of the two products did not change over time, as Copper Wirerod always held a higher standing than Aluminum Wirerod in global trade.
