The specific gravity of aluminum is 2.69, which is only about a third of that of iron (7.87) and copper (8.9). In response to the demand for performance improvement by reducing the weight of various parts and materials, aluminum is being used in the transportation field of automobiles, railways, aircraft, and ships. Operating efficiency of high-speed rotating parts of various machines has been increased by utilizing the light weight characteristics of aluminum, thereby suppressing the weight increase due to the enlargement of the device, etc.

Aluminum reacts with oxygen in the atmosphere to form a thin and dense oxide film on the surface. Aluminum alloys that combine corrosion resistance and strength are used for various purposes, especially in fields like construction, automobiles, ships, and offshore development.

Aluminum is easy to perform plastic processing such as extrusion, rolling, forging, and molding.
Thin sheets such as paper and extruded forms of complex shapes can be easily manufactured. In addition, it is relatively easy to perform secondary molding processing or precision processing on the surface of the product that has been processed first, and it has excellent cutting processability.

Because the heat conduction of aluminum is 5 times that of iron, the electrical conductivity of copper is about 60%, the electrical conductivity of aluminum is about 60% of copper, and the weight is only about 1/3, which makes it conduct the current twice more than copper by weight. Currently, it is widely used in high-voltage transmission lines and conductors, and the demand in the electric and electronic fields is also significantly growing. Thermal conductivity of aluminum is about 5 times that of iron, and this characteristic is applied to heat-cooling and heating equipment, engine parts, various heat exchangers, solar collectors, and beverage cans. It is also used for heat sinks to prevent overheating of recent high-density devices and systems.

Aluminum can get corrosion-resistant coatings with various colors and hardness by anodizing surface treatment. Aluminum is a beautiful metal in itself, but it becomes more beautiful through surface treatment such as anodization and coating treatment, and can increase resistance in corrosion and abrasion by increasing hardness of the surface.

Energy required to regenerate aluminum is only 3% of the energy used to manufacture new metals from raw stones. Compared to other metals, aluminum is difficult to oxidize and has a low melting point, so it can be easily recycled by melting used aluminum products. Raw material (Characteristics of aluminum)
