The density of aluminum is often used in the calculation of aluminum profiles. Aluminum is a chemical element belonging to the boron group. Its chemical symbol is Al and its atomic number is 13. The relative density is 2.70. Aluminum is a relatively soft, ductile, silver-white metal. Aluminum is the third most abundant element in the Earth's crust (after oxygen and silicon) and the most abundant metal, accounting for about 8% of the Earth's solid surface by mass. Aluminum metal is chemically active, so it is generally difficult to find free metal aluminum unless it is in a very special redox environment. More than 270 minerals containing aluminum have been discovered.high strength aluminium price - YuanfarAluminum

The most important aluminum-bearing ore is bauxite

Aluminum is valued for its low density and resistance to corrosion (due to passivation). Structural parts made from aluminum and its alloys are critical not only in the aerospace industry, but also in the fields of transportation and structural materials. The most useful aluminum compounds are its oxides and sulfates.

Despite the widespread presence of aluminum in the environment, none of the life forms contain aluminum salts.

The density of pure aluminum is 2.7×10³kg/m³ or 2.7g/cm³;

Other series have different alloys, ranging from 2.58 to 2.9.

Aluminium (metal element) silver-white light metal. Extensible. Commodities are often made into rods, sheets, foils, powders, ribbons and filaments. In moist air, it can form an oxide film that prevents metal corrosion.

Aluminum powder can burn violently when heated in the air, and emit a dazzling white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water.

Relative density 2.70. Melting point 660 ℃. Boiling point 2327 ℃. 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 that the material properties have the unique properties of aluminum and its alloys, which is greatly beneficial to the production and application of this new metal aluminum. The application is very wide.

On October 27, 2017, the list of carcinogens published by the World Health Organization's International Agency for Research on Cancer was preliminarily sorted out for reference, and aluminum products were included in the list of Class I carcinogens.
