About Cast iron
Cast iron is an iron-based casting alloy whose properties depend on its composition and microstructure. It is characterised by good castability and a range of hardness, strength, and ductility, making it suitable for machine bases, housings, pipes, engine components, and wear-resistant parts.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.
Chemical composition
7 elements on file · weight %What this alloy is
Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade.

The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other.

Physical & mechanical properties
An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material.
