成本端坚挺提供支撑，铸造铝继续高位区间震荡

Core Viewpoint - The casting aluminum market is experiencing a mixed performance due to supply and demand dynamics, with prices supported by high costs and limited supply, while demand remains inconsistent [1][2][3]. Group 1: Price Trends - The main contract for casting aluminum alloy (2602) closed at 21,235 CNY, up 115 CNY, with a trading volume of 4,335 lots, a decrease of 297 lots, and an open interest of 17,216 lots, an increase of 26 lots [1]. - The average price for various casting aluminum alloys has increased by 100 CNY, with A356.2 at 23,200 CNY/ton, A380 at 22,800 CNY/ton, ADC12 at 21,600 CNY/ton, ZL102 at 22,600 CNY/ton, and ZLD104 at 22,500 CNY/ton [1]. Group 2: Market Analysis - The macroeconomic environment shows a decrease in inflation pressure, with the U.S. consumer price index rising by 2.7% year-on-year in November, below the expected 3.1%, which has improved market sentiment [1]. - Despite the positive sentiment, the strong U.S. dollar has countered some of the bullish effects, leading to price fluctuations in the casting aluminum market [1]. - The casting aluminum supply and demand are both experiencing reductions, with high aluminum alloy prices and limited production capacity due to losses in the smelting sector [2]. Group 3: Demand and Supply Dynamics - Demand for casting aluminum is inconsistent, with some support from the automotive sector, but overall market activity remains subdued due to delivery pressures [2]. - Sellers are reluctant to lower prices, which further suppresses the willingness of downstream buyers to replenish stocks, affecting overall market activity [2]. - The price performance of casting aluminum is primarily supported by high costs of scrap aluminum, and it is expected to maintain a high-level oscillation in the future [3].
