Supertech pistons are manufactured from extruded high silicon, enhanced 4032 alloy (with additional Cu, Ni & Mg) that has low thermal expansion, excellent wear resistance and higher thermal conductivity. 

A 2 or 3 forging steps process yields a fine structural grain oriented in fibres in the same direction of the stresses.
