The piston material in internal combustion engines is typically made of a high-strength aluminum alloy. Aluminum alloys are commonly used due to their lightweight nature, good thermal conductivity, and high strength-to-weight ratio. These properties allow the piston to withstand the high temperatures and pressures inside the combustion chamber while minimizing weight and maximizing engine efficiency. Additionally, the aluminum alloy can be engineered to have low expansion characteristics, reducing the clearance between the piston and the cylinder wall, which helps maintain efficient combustion and reduces noise.
