“铜铝比”接近4，铝将是下一个站上风口的金属？

Core Viewpoint - The global metal market is experiencing a significant surge, with aluminum potentially becoming a key player despite its relatively low price increase this year compared to other metals [1][2]. Demand Factors - The substantial rise in copper prices, which have increased over 20% this year, is expected to drive demand for aluminum as a substitute material [2]. - Aluminum is recognized as one of the four critical metals needed for the transition to renewable energy, alongside copper, lithium, and steel [4]. - The electric vehicle (EV) sector is a major growth area for aluminum demand, with EVs using approximately 150 pounds more aluminum than internal combustion engine vehicles [5]. - Aluminum plays a crucial role in the automotive industry, particularly in popular models like the Ford F-150, which has adopted aluminum to reduce weight [6]. Supply Constraints - Despite increasing demand, the supply of aluminum is constrained by electricity availability, which is essential for aluminum production [7]. - China's aluminum production is nearing a government-imposed cap of 45 million tons, leading to expectations of a shift from oversupply to potential shortages [7]. - The U.S. aluminum industry faces challenges in securing electricity contracts due to competition from tech companies, which are willing to pay significantly higher rates for power [8]. - Analysts predict that the global surplus of primary aluminum will decrease rapidly by 2026, leading to a projected shortfall of approximately 1.4 million tons by 2027 [8].
