Product Information

Cast iron is a group of iron-carbon alloys with a carbon content greater than 2%. Carbon is excreted in the form of graphite or carbide. Iron alloys with lower carbon content are known as steel.

Compared to wrought iron, cast iron is characterized by high compressive strength, thermal conductivity, better pourability (the result of lower melting point) and slower progress of corrosion. However, due to its structure, cast iron tends to be brittle and exhibits poor formability.

The method of excluding graphite (its shape and size) from pig iron determines the properties of cast irons, and therefore its types: grey cast iron, ductile cast iron, white cast iron, malleable cast iron and vermicular cast iron.

Grey cast iron, i.e. cast iron with flake-like graphite structure, is the most common type. Its grade is derived from tensile strength. It has good lubricating properties, so it is suitable in production of low-stress plain bearings. It is used in engines, fittings, radiators, in the construction industry or for artistic castings.

Ductile cast iron, i.e. cast iron with spheroidal graphite, has higher carbon content than grey iron. Its key properties are greater ductility and flexibility. Ductile iron is widely used in the automotive industry.

We supply cast iron in the form of round, flat and square bars or bushings (hollow bars).
