Characteristics of aluminum
Aluminum has a series of better characteristics than other non-ferrous metals, steel, plastics, and wood, such as low density, only 2.7g/dm³, which is about one-third of copper or steel and has good corrosion resistance and weather resistance. Performance, good plasticity and processing performance, good thermal and electrical conductivity, good low-temperature resistance, high reflectivity to photothermoelectric waves; good surface performance, non-magnetic, basically non-toxic; sound absorption, good acid resistance, Good nuclear radiation resistance; small elastic coefficient, good mechanical properties; excellent casting performance and welding performance; good impact resistance.
