Ideal for specialty applications like activated alumina or HPA. However, they may lack scale economies and consistent quality.<\/p>\n<p><strong>Large Factories (e.g., Chalco, Weiqiao):<\/strong> Provide stable supply for large volumes (10,000+ MT), lower per-unit cost, and rigorous quality control.
