国内外供应皆充裕，氧化铝难改弱势

1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints of the Report - Both domestic and overseas alumina supplies are abundant, especially the overseas prices have accelerated their decline in the past week. The theoretical import window has slightly opened. If it persists, increased imports in the next two months may exacerbate the domestic oversupply situation. The consumption side remains relatively rigid, and the rising warehouse receipt inventory continues to exert pressure. Alumina is expected to remain weak [2][6]. 3.
