Aluminum Foil Roll Supplier In China
Aluminum foil belongs to aluminum metal processing products, and its industrial chain is similar to that of aluminum material. The industry is greatly affected by upstream raw materials. From the perspective of production and market conditions, China is the largest producer of aluminum foil.
The aluminum foil industry chain can be divided into upstream raw material supply industry, midstream aluminum foil manufacturing industry, and downstream demand industries. The specific process flow of aluminum foil is the process of converting bauxite into alumina by Bayer method or sintering method, and then using alumina as raw material to produce primary aluminum by high-temperature molten salt electrolysis. After adding alloying elements, electrolytic aluminum is processed into aluminum foil through extrusion, rolling, etc., which is widely used in packaging, air conditioning, electronics and other fields.
The upstream raw materials of aluminum foil are mainly primary aluminum aluminum ingots and aluminum billets, that is, higher-purity electrolytic aluminum and recycled high-purity aluminum. From the perspective of the average cost composition of aluminum foil, 70%-75% of the production cost per unit of aluminum foil comes from raw materials.
China's aluminum foil coil industry has continued to develop rapidly in recent years, the scale of the industry has grown rapidly, the level of equipment has been continuously improved, technological innovation has been strengthened, product quality has been continuously improved, international trade has been highly active, and leading companies have continued to emerge. Overall, China's aluminum foil industry is still in an important period of opportunity for development.
