HY450
Aluminum is a metallic element with the symbol Al and atomic number 13. Its elemental 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. Easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide, and potassium hydroxide solutions, but insoluble 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 the three important industries of aviation, construction, and automotive requires the unique properties of aluminum and its alloys in material properties, which greatly facilitates the production and application of this new metal aluminum. The application is extremely extensive.
