Brief description of aluminum products

Aluminum products are collectively referred to as daily necessities and industrial products made of aluminum alloys.

  Aluminum is a chemical element. Its chemical symbol is Al and its atomic number is 13. The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third, and is the most abundant metal element in the earth's crust. Among the metal species, second only to steel, it is the second largest metal. By the end of the 19th century, aluminum had emerged as a competitive metal in engineering applications and it was popular. The development of aviation, construction, and automotive three important industries requires that the material properties have the unique properties of aluminum and its alloys, which greatly benefits the production and application of this new metal aluminum. Aluminum is widely used.

  Pure aluminum is soft, has low strength, and has good ductility. It can be drawn into filaments and rolled into foils. It is widely used in the manufacture of wire, cable, radio industry, and packaging industries. Its electrical conductivity is about two-thirds that of copper, but because its density is only one-third that of copper, aluminum has approximately the same electrical conductivity as copper of equal length and copper wire. Doubled, and the price is lower than copper.

Aluminum alloys are aluminum based alloys. The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the minor alloying elements are nickel, iron, titanium, chromium, and lithium.

  Aluminum alloy has low density, but high strength, close to or more than high-quality steel, good plasticity can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the amount of use is second only to steel.
