Processing characteristics of aluminum alloy body parts

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

(2) During machining, aluminum can be prone to tool sticking, which may lead to chipping or poor surface finish. The roughness of the machined surface tends to be higher due to this behavior.

(3) The microstructure of aluminum is not as dense as other metals, making it more challenging to achieve a very fine surface finish. This can affect the quality of the final product, especially in precision applications.

(4) Despite some challenges, aluminum alloys often result in longer tool life because they are less abrasive than harder materials like copper. This can reduce maintenance and replacement costs over time.

(5) Aluminum is also more susceptible to deformation during loading and processing. This can cause the workpiece surface to become scratched or damaged, affecting both aesthetics and functionality.

(6) Another important characteristic of aluminum is its relatively high thermal expansion coefficient. This means that dimensional accuracy must be carefully controlled during manufacturing, especially when temperature changes are involved.
