With more than 40 years of experience in the development of racing pistons and the use of the latest CAD software, including finite element analysis (FAE), Supertech is able to design very stable yet lightweight pistons for every application. The pistons are manufactured in Argentina according to European specifications.
The pistons are made of extruded, pure silicon (extended 4032 alloy with additional Cu, Ni and Mg), which has low thermal expansion, excellent wear resistance and high thermal conductivity. Pistons with this alloy have withstood a charge pressure of over 2.9 bar with alcohol as fuel without any problems. In the 2- or 3-step forging process results in a fine grain structure, which are aligned in the same direction of the fiber as the stress. By multiple heat treatment, the pistons receive a uniformly distributed high tensile strength and hardness.
In several processing steps, the pistons are machined in special machines and on conventional CNC machines with special diamond tools to ensure high dimensional accuracy, squareness and flatness of the ring grooves. The piston pins are made of chrome molybdenum steel. Then the "phosphate dry lubricant" coating is applied to protect the rings against "microwelding" and to improve lubrication in the cylinder.
