Speaking of aluminum wire, I believe that many friends have some understanding of it. This kind of metal material has been used in many industries, and it is also a very important metal product in people's life. As a kind of silver-white light metal, it has good ductility and malleability. It can form a layer of oxide film to prevent metal corrosion in the humid air, and has a wide range of applications in aviation, construction and automobile three important industrial fields.
The density of aluminum wire is very small, only 2.7g/cm, although it is soft, but can be made into a variety of aluminum products, in aircraft, automobiles, ships and other manufacturing industry has a wide range of applications, in addition, space rockets, space shuttle, artificial satellites also use a lot of aluminum and aluminum wire.
Aluminum's electrical conductivity is second only to silver and copper. Although its conductivity is only 2/3 of copper's, its density is only 1/3 of copper's, so the quality of aluminum wire is only half that of copper wire when it delivers the same amount of electricity. The oxide film on the surface of aluminum not only has the ability of corrosion resistance, but also has certain insulation, so it has a wide range of applications in the electrical manufacturing industry, wire and cable industry and radio industry.
At the same time, aluminum wire is a good conductor of heat, its thermal conductivity is 3 times larger than iron, industrial aluminum can be used to manufacture a variety of heat exchanger, heat dissipation materials and cookware; It also has good ductility, its ductility is second only to gold and silver, at 100 degrees Celsius to 150 degrees Celsius, can be made into thin 0.01mm aluminum foil, these aluminum foil is widely used in packaging cigarettes, candy, etc., can also be made into aluminum strips, aluminum wire, and can roll a variety of aluminum products.
