Processing characteristics of aluminum alloy body parts

(1) Aluminum alloys have lower strength and hardness compared to copper, but they offer better machinability. This makes them easier to cut and shape during the manufacturing process.

(2) However, during machining, aluminum tends to stick to the cutting tool, which can lead to chipping or wear of the tool. This also results in a rougher surface finish on the machined part.

(3) The microstructure of aluminum is not as dense as that of other metals, making it more challenging to achieve a fine surface finish. Proper tooling and techniques are essential for improving surface quality.

(4) Despite these challenges, the tool life for aluminum machining is generally longer than for harder materials. This is due to the relatively low cutting forces involved.

(5) Aluminum is also prone to deformation during loading and processing. Additionally, the workpiece surface can easily get scratched or damaged, especially if not handled carefully.

(6) Another important characteristic is its higher thermal expansion coefficient. This means that dimensional accuracy must be closely monitored, particularly when working with tight tolerances or in high-temperature environments.
