Aluminum is a silver-white light metal. There is malleability. Commodities are often made into rods, sheets, foils, powders, ribbons and filaments. It can form an oxide film to prevent metal corrosion in humid air. Aluminum powder and aluminum foil can burn violently when heated in the air and emit a dazzling white flame.
Overview of China's aluminum profile industry
After more than 50 years of development, China's aluminum profile industry has become the world's largest aluminum profile producer. As of 2007, there are more than 600 aluminum extrusion plants in production in China, with about 3,500 extrusion production lines ranking first in the world in terms of number, production capacity, and output. It has become the world's largest producer of aluminum extrusion materials; With structural adjustments and market adjustments, the number of aluminum processing plants has decreased and their distribution is gradually dispersed; product exports have increased, becoming the world's most important aluminum profile production and net export country.
In 2007, China's aluminum net exports increased by 110.0%. Among them, the contribution of flat rolled products is obvious. The export of profiles was 845,000 tons, an increase of only 24.1% over 2006, and the growth rate was down 56.1% year-on-year. Mainly affected by the sluggish real estate industry in Europe and the United States and the cancellation of export tax rebates on July 1.
It is easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, but hardly soluble in water. The relative density is 2.70. Melting point is 660°C. The boiling point is 2327°C. The content of aluminum in the crust is second only to oxygen and silicon, ranking third, and is the most abundant metal element in the crust. The development of the three important industries of aviation, construction, and automobiles requires the characteristics of materials to have the unique properties of aluminum and its alloys, which greatly facilitates the production and application of this new metal aluminum. The application is extremely wide.
