Copper occupies a strategic position in the global economy, in defense and security, in the energy transition process and in the international competition for resources. Its significance is analyzed in a number of dimensions:
Industrialization and GDP Correlation
Each unit of GDP growth requires about 0.9kg of copper support, and every 1% growth in China's GDP in 2025 corresponds to 78,000 tons of copper demand. Copper, as "industrial blood", is indispensable in key areas such as power transmission (e.g., 7.5 tons of copper per kilometer of ultra-high-voltage grid), new energy vehicles (single-vehicle use of 28kg, four times the amount of fuel vehicles), electronic equipment and other key areas.
Cornerstone of emerging industries
Copper is the core material for new energy technologies such as photovoltaic (5,000 tons per GW), wind power (3,800 tons per GW), and energy storage batteries (the thickness of copper foil for lithium-ion batteries has exceeded 4 μm), which directly contributes to the global energy transformation process.
Key Materials for Information Warfare
Radar system containing copper up to 18% of the total weight of the equipment, electromagnetic artillery need purity ≥ 99.99% copper alloy, aircraft carrier electromagnetic catapult system single set of copper consumption of 8 tons, nuclear submarine cooling system copper pipe dosage of 25 tons. These applications of copper conductivity, corrosion resistance requirements are extremely high, recycled copper due to impurities difficult to meet the needs of the military industry.
Rigid demand for strategic equipment
The military field is highly dependent on virgin copper, and the supply of copper resources is directly related to the research and development and maintenance capabilities of national defense equipment.
The core carrier of global energy transformation
Clean Energy Infrastructure
The demand for copper in the fields of photovoltaic, wind power and power grid upgrading is surging. The International Energy Agency predicts that global copper demand will exceed 31 million tons by 2030 and reach 50 million tons by 2050, of which new energy fields account for more than one-third.
Breakthrough in energy storage technology
Power battery copper foil technology (such as Zijin Mining's high-precision copper foil) is the key to improving battery performance, and it is expected that the global power battery copper demand in 2025 will reach 680,000 tons.
Resource scarcity and geopolitical game focus
Highly concentrated resource distribution
50% of global copper reserves are concentrated in Chile, Peru and DRC, China's self-sufficiency rate is less than 30%, and its dependence on foreign countries reaches 72%, while the development rate of Tibet's Gangdis copper belt is less than 30%.
International strategic reserve and technology monopoly
The U.S. copper strategic reserves of 450,000 tons, the European Union to establish a 30-day consumption of emergency reserves; high purity copper (purity 99.9999%) purification technology by the U.S. and Japan's monopoly, China's dependence on imports reached 85%.
Prioritization of national policies and industrial upgrading
China's Policy Orientation
The Implementation Plan for High Quality Development of Copper Industry (2025-2027) proposes: 10% growth in domestic copper resources by 2027, increasing the proportion of recycled copper to 35%, cultivating international first-class mining groups, and smelting production capacity concentration of more than 75%.
Direction of technological breakthrough
Focus on key technologies such as intelligent mining, low-carbon smelting and high-end copper foil, and promote the upgrading of the industrial chain to green and intelligent.
Future Challenges and Strategic Responses
The global copper supply is expected to have a 10-million-ton gap by 2035. Countries are competing for the initiative through resource control (e.g., the U.S. holding Chilean copper mines, the EU investing in Africa), deep-sea mining (China exploring polymetallic sulfides in the Southwest Indian Ocean), and recycling economy (improving recycling rate of recycled copper), and other strategies.
Copper's strategic position has transcended the traditional industrial metal category, becoming a core element of global energy transition, national defense and security, and economic competition. Its supply and demand dynamics and technological breakthroughs will profoundly affect the future international resource pattern and national comprehensive strength.
