Aluminum alloy is a general term for daily necessities and industrial supplies processed from the main raw materials. Aluminum alloy is a general term for aluminum based alloys. The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the minor alloying elements are nickel, iron, titanium, chromium, lithium and so on.
Aluminum alloy density is low, but the strength is relatively high, close to or more than high-quality steel, good plasticity can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the use of second only to steel.

Aluminum is a chemical element. Its chemical symbol is Al and its atomic number is 13. The content of aluminum in the crust is second only to oxygen and silicon, ranking third, and is the most abundant metal element in the crust. In the metal varieties, second only to steel, for the second major category of metal. By the end of the 19th century, aluminum had emerged as a competitive metal in engineering applications and was all the rage. The development of three important industries, aviation, construction and automotive, requires material properties with the unique properties of aluminum and its alloys, which greatly facilitates this new
Metallic aluminium
Production and application. Aluminum is widely used.
Pure aluminum is very soft, not strong, has good ductility, can be drawn into filaments and rolled into foils, a large number of wire, cable, radio industry and packaging industry. Its conductive capacity is about two-thirds of copper, but because its density is only one-third of copper, the conductive capacity of aluminum is about twice that of copper compared with aluminum wires of equal quality and length, and the price is lower than copper.

Aluminum was once used to make cookware, and very popular, because aluminum pot is not easy to rust, aluminum in the air will react with oxygen to form a dense alumina film, but scientific proof, aluminum tableware is not suitable for cooking or long-term storage of acidic, alkaline and salty food, because the acid and alkali salt can directly etch the protective film on the surface of aluminum metal and aluminum products themselves. Studies have found that aluminum can damage brain cells. On the basis of
World Health Organization
The daily intake of aluminum is 0 to 0.6mg/kg, where the kg refers to the body weight of the person, that is, the allowable intake of a 60kg person is 36mg. China's "standard for the use of food additives GB2760-2011" stipulates that the residual amount of aluminum is less than or equal to 100mg/kg. Aluminum accumulates slowly in the human body, and the toxicity it causes is slow and imperceptible, however, once it occurs
Metabolic disorder
The toxic reaction, the consequences are very serious. Therefore, we must pay attention to prevent the absorption of aluminum in daily life and reduce the use of aluminum products. Therefore, aluminum cookware has been gradually phased out. Standard for the use of food additives GB2760-2011
