Edit:admin Date: 2019-04-24 16:18
Aluminum is the main group of elements in the third cycle of the periodic table with an atomic number of 13 and an atomic weight of 26.9815.
Aluminum has a series of better properties than other nonferrous metals, such as iron and steel, plastics and wood, such as low density, only 2.7g / cm3, is about 1 km3 of copper or steel, good corrosion resistance and weathering resistance, good plasticity and processing properties; Good thermal conductivity and conductivity; good low temperature resistance; high reflectivity to photothermal waves; good surface properties; non-magnetic; basically non-toxic; sound absorption; good acid resistance; good nuclear radiation resistance; small elastic coefficient; Good mechanical properties; excellent casting and welding properties; good impact resistance.

In addition, the high temperature properties, molding properties, machinability, riveting and surface treatment properties of aluminum are also better. Therefore, aluminum materials in aerospace, navigation, aviation, automobile, transportation, bridges, construction, electronic and electrical, energy power, metallurgical chemicals, agricultural irrigation and drainage, machinery manufacturing, packaging anticorrosion, electrical furniture, Daily products and other fields have been widely used.
