Introduction to Aluminum

Aluminum is a metal element with the element symbol of Al and Atomic number of 13. Its simple substance is a silver white Light metal. It has extensibility. Products are often made into rods, sheets, foils, powders, ribbons, and filaments. A layer of oxide film can be formed in humid air to prevent metal corrosion. Aluminum powder can burn fiercely when heated in the air and emit a dazzling white flame. It is easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solutions, and is difficult to dissolve in water. Relative density 2.70. Melting point 660 ℃. Boiling point 2327 ℃. Aluminum is the most abundant metal element in the Earth's crust, ranking third in content after oxygen and silicon. The development of three important industries, aviation, construction and automobile, requires that the material properties have unique properties of aluminum and its alloys, which is greatly conducive to the production and application of this Nu metal aluminum. The application is extremely extensive.
