Which material are used in piston construction?

Pistons are typically constructed from materials such as aluminum alloys, which offer a good balance of strength, lightweight properties, and thermal conductivity. Some high-performance pistons may use forged steel or titanium for increased strength and durability. Additionally, certain applications may utilize composite materials or special coatings to enhance wear resistance and reduce friction. The choice of material often depends on the specific requirements of the engine and its operating conditions.
