Aluminum is a silvery white light metal. It has plasticity. Commodities are often made into bars, sheets, foils, powders, tapes and wires. An oxide film can be formed in humid air to prevent metal corrosion. Aluminum powder can burn violently when heated in air, and give off a dazzling white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water. The relative density is 2.70. The melting point is 660℃. The boiling point is 2327℃.
Extended data
Aluminum is a light metal with chemical symbol Al and atomic number: 13. 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, and its reserves rank second among metals. Among the metal varieties, it is the second largest metal after steel.
After Italian physicist Volta invented the battery, David tried to separate aluminum from bauxite by current, but failed. However, he suggested that it be named "alumium", later changed to "Alumnium" and soon changed to Aluminum. This word form is very common all over the world, except in North America, the American Chemical Society (ACS) decided to use "aluminum" in its publication 1925.
