Piston Materials
Pistons form a combustion seal and transmit forces from combustion to the connecting rods. Pistons are made from either low-carbon steel or aluminum alloys. The piston is subjected to high heat, inertia, vibration, and friction. Carbon steels minimize the effects of differential thermal expansion between the piston and cylinder walls. The lowered weight of aluminum compared to cast iron is lost due to thicker sections needed for strength.
Carbon steel pistons are made from SAE G2500 grade gray iron. Gray iron has good fluidity at elevated temperatures. This is a valuable property since most pistons are formed from squeeze casting.
Aluminum pistons are made from alloy with a relatively high concentration of silicon. Aluminum high in silicon improves wear resistance, compared to low concentrations of alloying elements. Thermodynamic properties allow a more uniform distribution of silicon and less segregation. Other aluminum alloys include 356 and 390 grades, containing low compositions of silicon (3% to 8%).
