What is aluminum (alliage d'aluminium)?
Aluminum is a metal element with abundant reserves on earth. It is widely used in industry and life, and has many excellent properties.
What are the characteristics of aluminum alloy?
1. Low density.
The density of aluminum is 2.7g/cm³, the ductility is good, and the conductivity is two-thirds that of copper wire, but the quality is only one-third, and the price is cheaper. It is widely used in the manufacture of high-voltage wires, cables, radio industries. .
2. Good ductility.
Aluminum has good ductility, and at 100 ℃ ~ 150 ℃, it can be made into deep-processed products such as aluminum foil, bobine d'aluminium, and aluminum circle thinner than 0.01 millimètre.
3. Bonne résistance à la corrosion.
Aluminum will form a dense oxide protective film on the surface in the air, making it resistant to corrosion, so it is often used to manufacture medical equipment, marine ship plates, tanks, etc.
4. Low temperature resistance
When the temperature of aluminum is low, its strength increases without brittleness, so it is ideal for low-temperature installation materials, such as refrigerators, freezers, Antarctic snow vehicles, etc.
