Chemical Attributes
Although aluminum as an active metal is easily oxidised in the air, the internal oxidation is prevented as the dense alumina is formed on its surface. This oxidised film of the surface is the combined oxidised layer of the dense film from the inside and the hydrated film on the surface. This oxidised film of the surface is artificially made by the anode oxidation, and its corrosion resistance and internal abrasion proclivity is excellent.
Mechanical Attributes
The mechanical attribute of aluminum varies depending on the purity degree, processing amout and heat treatment. As the cold working rate increases, its intensity is heightened by the work hardening , its ductility ia lowered, and it is softened by annealing. The addition of an alloy element lardens the material because of solution hardening and precipitation hardening. In general, as the employment amount of an alloy element increases, so does the intensity. The larger the difference of the atom radius aluminum and alloy element is, the more conspicuously this attribute of aluminum appears. |
