C003B Alloy Aluminum

Aluminium (Aluminium) is a metal element, the element symbol is Al, which is a silver-white light metal. There is malleability. Commodities are often made into rods, flakes, foils, powders, ribbons and filaments. It can form an oxide film to prevent metal corrosion in humid air. Aluminum powder can burn violently 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 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 earth's crust is second only to oxygen and silicon, ranking third, and it is the most abundant metal element in the earth's 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.
