CNC Machining Aluminum Parts And Other Metal Materials

CNC machining is widely used for manufacturing aluminum and other metal materials, with aluminum being particularly favored due to its unique advantages. Compared to iron or copper, aluminum offers the following characteristics:

1. Low Density

   • The density of aluminum and aluminum alloys is approximately 2.7 g/cm³, which is only one-third that of iron or copper, making it an ideal choice for lightweight applications.

2. High Strength

   • High-strength aluminum alloys provide excellent mechanical properties while maintaining a lightweight structure, ensuring durability and reliability.

3. Excellent Thermal Conductivity

   • Aluminum has outstanding thermal conductivity, second only to silver, copper, and gold, making it widely used in industries requiring efficient heat dissipation, such as electronics and automotive manufacturing.

4. Superior Corrosion Resistance

   • The surface of aluminum naturally forms a dense Al₂O₃ oxide protective layer, effectively preventing corrosion. Additionally, anodizing and coloring treatments can further enhance its durability and aesthetics.
