Aluminum alloy and aluminum temper designations
1.Aluminum alloy features The density of aluminum is 2.7 g/cm³, which is about 1/3 of that of steel (7.8 g/cm³). Substituting aluminum alloy for steel can reduce weight by about 50%. Since the surface of aluminum is easily oxidized to form a dense and stable oxide film (passivation), it has good corrosion resistance. Aluminum has …
