Chapter I Industry Overview
1.1 Overview of aluminum industry
Aluminum is a metal element with the element symbol of Al and atomic number of 13. Its simple substance is a silvery white light metal. Ductility. Goods are often made into rods, sheets, foils, powders, ribbons and filaments. An oxide film can be formed in humid air to prevent metal corrosion. Aluminum powder can burn violently when heated in the air and emit dazzling white flame. Easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, but not in water. The relative density is 2.70. The melting point is 660 ℃. The boiling point is 2327 ℃.
The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third. It is the most abundant metal element in the earth's crust. The development of the three major industries of aviation, construction and automobile requires that the material properties have the unique properties of aluminum and its alloys, which is greatly conducive to the production and application of this new metal aluminum. It is widely used.

Double-carbon enabling, renewable aluminum enters the golden age

Based on the long-term logic of tight supply side, we predict that the global aluminum-based materials may maintain a tight balance between supply and demand before 2025, and the gap between supply and demand may continue to expand after 2025, and aluminum prices may stabilize. There are liters in the middle. Under the background of "dual carbon", the supply structure dominated by thermal power aluminum is facing transformation, and the replacement space for hydropower aluminum is limited. Recycled aluminum may become an important source of supply in the future. We predict that the CAGR of recycled aluminum output may reach 8.2% in 20-30 years, and in the future The long-term growth rate may be maintained at around 4%. At the same time, the profitability of recycled aluminum is positively correlated with aluminum prices, and recycled aluminum companies may benefit from rising aluminum prices at the same time, which is expected to enter the development stage of both volume and price. In addition, we are optimistic about companies that have both recycled aluminum and aluminum processing businesses.
