Iron Foundry Products

Increasing demands from end-users and the development of new alloys to meet weight and strength demands have presented new challenges to the iron foundry industry. Elkem has developed packages of alloys combined with technical services and R&D to meet these requirements;

A range of over 100 nodularisers to suit every ladle size, design and capacity means that there is an alloy which will give the optimum magnesium recovery in your foundry

Elkem’s portfolio of inoculants provide the ideal level of nucleation to maximise mechanical properties and reduce shrinkage, poor graphite forms and chill in all irons

Backed by an experienced sales force and a global Technical Service Team, Elkem is the ideal partner in providing solutions to the iron foundry industry.

Iron foundry products

Elkem manufactures a wide range of inoculants, MgFeSi alloys and preconditioners for the production of cast irons. Alloys are available from the extensive portfolio to cover all foundry conditions and iron qualities.


For many years, Elkem’s flagship inoculant has been the world famous Superseed® inoculant, probably still the most widely used in the production of grey iron globally. Today we have a portfolio of inoculants designed to cover a wide range of applications in all cast iron segments.


Elkem produces an extensive range of MgFeSi alloys for the production of ductile and compacted graphite irons. Alloys are available in chemistries and sizes to suit all foundry applications - sandwich, tundish, flow-through, in-the-mould or other processes. We work with our customers to provide technical support and advice on maximising the value obtained from the use of our nodularisers. Low Mg alloys and alloys to counter shrinkage have become major areas of development and application in recent times, resulting in cost savings, increased productivity and improved environmental measurements.

Preconditioners and cover materials

Elkem has developed an alloy which may be added to the furnace during melting to stabilise the nuclei within the iron. This is called Preseed® preconditioner.

To maximise Mg recovery in ladle treatments and condition slag to a controllable form, a special cover material is available, TopseedÒ alloy.
