The material in pistons has evolved over the years primarily due to advancements in technology and the need for better performance, durability, and fuel efficiency. Modern pistons are often made from lightweight aluminum alloys, which offer improved thermal conductivity and reduced weight compared to traditional cast iron. Additionally, the introduction of advanced coatings and treatments has enhanced wear resistance and reduced friction, allowing for higher engine speeds and efficiency. Overall, these material changes reflect a continuous drive to optimize engine performance and meet stricter emissions standards.
