As a city covering the entire industry chain of "bauxite-alumina-aluminum-aluminum deep processing-secondary aluminum," Sanmenxia is taking "extending, supplementing, and strengthening the chain" as a breakthrough to drive the aluminum industry's transition from "resource dependence" to "innovation-driven." The city currently has 24 key aluminum industry enterprises, with an annual production capacity of 5.1 million mt of alumina, 240,000 mt of aluminum, 450,000 mt of aluminum deep processing (aluminum plate/sheet and strip, aluminum extrusion, etc.), and 6 million wheel hubs. In the aluminum-based new materials industry chain, a pattern has formed with leading enterprises such as East Hope, Kaiman Aluminum, Hengkang Aluminum, and Baowu Aluminum. By 2024, the city's aluminum industry output value is expected to exceed 26 billion yuan, and an aluminum-based new materials industry chain characterized by resilience, innovation, and green development is rapidly emerging.
