Weight-optimized pistons for passenger car gasoline engines are cast or forged
from high temperature resistant aluminum alloys.
As a result of advanced casting technology ECOFORM® pistons
offer low weight and high structural rigidity.
Piston skirts usally have a graphite coating. For
application in aluminum bores a FERROSTAN® iron
coating or an iron particle-reinforced synthetic resin
coating – FERROPRINT® – is applied.
