Spheroidal iron (EN-GJS): EN-GJV-450

High ductility and great tensile strength

Spheroidal iron shows high ductility. And even more. It possesses an extremely high solidity, which is partly even higher than ductile and steel cast iron with identical ductility values.

An additional advantage of the material: through further alloying we can further improve abrasion resistance, heat and corrosion resistance.

Also for this the reason of the material characteristics lies in the structure of the iron-carbon alloy. The graphite shows a structure in the form of a small ball within the cast iron. Thus, spheroidal iron is also referred to as spherulitic graphite cast iron.

Applications: braking centres, pneumatic machine pistons, melting pots, compressor pistons, pump housings, tractor parts, agriculture machine parts, valves, airplane engine parts, moulds, machine parts, crank mills

Grey cast iron (EN-GJL):

High resistance to abrasion with good dampening characteristics

Grey cast iron is the most frequent used iron-carbon alloy. Its unique characteristic is its high abrasion resistance and its good pouring capability. Also the material is easy to process and it dampens extremely well mechanic vibrations.

The reasons for these physical characteristics lie in the structure of the cast iron. Carbon in grey cast iron is found in blades, which form three-dimensional ramifications. Yet, this bladed graphite is also responsible for the very low ductility of the material.

Applications: tubes, bars, nachine parts, tires, pumps, workbenches, flywheels, gear boxes,motor blocks, machine parts, pumps, compressor parts, petrol tubes, gears, manifolds, valves, pressure parts, rams
