grey cast iron (EN-GJL)
G= Cast iron J= Iron L= Lamellar graphite
Grey cast iron is the industrial name for cast iron with lamellar cast iron. The carbon precipitates during solidification in the form of graphite fins. The traditional name "grey cast iron" comes from the greyish appearance of the fracture surface of the casting. This is the most frequently used iron-carbon alloy as it has a very high wear resistance, excellent castability and good machinability by means of cutting processes. Furthermore, grey cast iron has a very low inclination to blowholes. All grey cast iron alloys are manufactured strictly in accordance with DIN EN 1561.

ductile cast iron (EN-GJS)
G= Cast iron J= Iron S= Nodular graphite
Ductile cast iron is the industrial name for cast iron with spheroidal cast iron, in which carbon is precipitated in the form of graphite balls during solidification. GJS can be regarded as a steel-like material and is characterised by its high elongation and tensile strength. Through targeted alloying, good temperature and corrosion resistance as well as higher wear resistance can be achieved. All spheroidal graphite cast iron alloys are manufactured strictly in accordance with DIN EN 1563.
