Reference national standard: aluminum ingot (GB/T1196-2017)

product description:

Aluminum is a silver-white light metal. Extensible. Commodities are often made into columns, rods, flakes, foils, powders, ribbons and filaments. In moist air, it can form an oxide film that prevents metal corrosion. It is widely used for its light weight, good electrical and thermal conductivity, high reflectivity and oxidation resistance. The aluminum used for daily utensils is usually called "steel" or "steel grade".

Application range and purpose:

The use of a substance depends to a large extent on the properties of the substance. Because aluminum has a variety of excellent properties, aluminum has an extremely wide range of uses. The density of aluminum is very small, and it can be made into various aluminum alloys, such as hard aluminum, super hard aluminum, rust-proof aluminum, cast aluminum, etc. These aluminum alloys are widely used in aircraft, automobile, train, ship and other manufacturing industries. In addition, space rockets, space shuttles, and artificial satellites also use a large amount of aluminum and its aluminum alloys.

The conductivity of aluminum is second only to silver, copper and gold. The oxide film on the surface of aluminum is not only resistant to corrosion, but also has a certain degree of insulation. Therefore, aluminum is widely used in electrical manufacturing industry, wire and cable industry and radio industry. .

Due to the dense oxide protective film on the surface of aluminum, it is not easy to be corroded.
