Aluminium - the main element of the subgroup of the third group of the third period of the periodic table of chemical elements of Mendeleyev, atomic number 13. Denoted by Al. Refers to a group of light metals. The most common metal and the third most common (after oxygen and silicon), chemical element in the Earth's crust.
Simple stuff aluminum (CAS-number: 7429-90-5) - easy, paramagnetic metal is silvery-white, pliable molding, casting, machining. Aluminium has high thermal and electrical conductivity, corrosion resistance due to the rapid formation of stable oxide films that protect the surface from further interaction.
Some biological studies intake of aluminum in the human body was considered a factor in the development of Alzheimer's disease, but these studies were later criticized and the conclusion of the relationship one with another refuted.
