● Structural Optimization: The design of aluminum alloy pistons often involves the use of finite element analysis (FEA) and other techniques to optimize the structure, ensuring the piston has the best distribution of strength and stiffness when subjected to combustion pressures.
● Cooling Channel Design: The top and sides of the piston may be designed with intricate cooling channels that help dissipate heat more effectively, reduce thermal stress, and enhance the durability of the piston.
● Wear-Resistant Coatings: To reduce wear, the piston skirt may be coated with special wear-resistant materials such as ceramic or diamond coatings, which provide additional protection and extend the lifespan of the piston.
● Oil Film Retention Grooves: The design of oil film retention grooves in the piston skirt helps maintain oil film stability during high-speed operation, reducing friction and wear, and improving the piston's performance.
● Lightweight Honeycomb Structure: By incorporating lightweight honeycomb structures in non-critical areas of the piston, it is possible to further reduce the weight of the piston, which enhances the engine's responsiveness and fuel efficiency.

● Lightweight: Compared to cast iron and steel pistons, aluminum alloy pistons are significantly lighter. This reduction in weight helps to decrease the overall weight of the engine, leading to improved engine power and fuel efficiency.
● Excellent Thermal Conductivity: Aluminum alloy pistons exhibit good thermal conductivity, allowing them to quickly disperse the high temperatures and heat generated by fuel combustion. This effectively lowers the engine's temperature and reduces thermal losses.
● Low Coefficient of Thermal Expansion: Aluminum alloy pistons have a relatively low coefficient of thermal expansion, ensuring stable operation under extreme conditions and reducing the probability of failure.
● Corrosion Resistance: Although aluminum alloy pistons may not have the highest corrosion resistance compared to some other materials, they are still capable of tolerating certain chemical substances, providing a degree of protection against corrosion.
● Durability and Wear Resistance: By optimizing the alloy composition, such as adding appropriate elements like tin (Sn), lead (Pb), zinc (Zn), chromium (Cr), and titanium (Ti), aluminum alloy pistons can be made more durable and wear-resistant.
