      Aluminum and its alloys have good appearance, light weight, machinability, good physical and mechanical properties and corrosion resistance, which make them economical and applicable in many fields. In terms of weight, the density of aluminum is only 2.7g/cm3, about one third of that of steel or copper, and aluminum of the same size will weigh much less.

      The surface of aluminum is highly reflective. After anodizing or dark anodizing, the surface of aluminum can effectively absorb or reflect radiant energy, visible light, radiant heat and electric wave. Polished aluminum has excellent reflectivity in a wide wavelength range, so it can be used in various applications that need reflection function or decoration.
