- Lightweight: Aluminum has a density of approximately 2.7 g/cm³, only about one-third that of steel or copper. Through alloying and heat treatment, its strength can approach that of ordinary steel, making it suitable for aerospace and transportation applications.
- Corrosion Resistance: Aluminum forms a dense, robust protective alumina film in the air, preventing further oxidation of the internal metal. Anodizing can artificially thicken this oxide film, resulting in enhanced corrosion resistance, wear resistance, and a wider range of colors.
- Electrical Conductivity: While not as conductive as copper, aluminum conducts twice the electricity per unit weight. Therefore, it is an economical and efficient choice for high-voltage transmission lines and power equipment.
- Excellent Machinability: Aluminum alloys have good machinability and are easy to CNC machine. They can be formed through various methods such as extrusion, rolling, forging, and stamping.
- High Temperature Resistance: Unlike some materials, aluminum retains its properties at low temperatures, providing greater flexibility in processing.
- Low Hardness: Pure aluminum has very low hardness. This low hardness can cause problems with CNC-machined parts. Therefore, manufacturers often use aluminum alloys instead of pure aluminum.
- Relatively High Cost: Although aluminum is abundant, it is more expensive than other industrial materials because it does not exist in a pure form; it must be extracted and processed from bauxite, which is costly.
- Easily Scratched and Bumped: Aluminum is relatively soft and scratches more easily than many other durable materials. Its shiny surface also makes these imperfections more noticeable.
