Technical advice

Elkem has a dedicated team of metallurgists and process engineers capable of addressing complex casting issues. Backed up by extensive laboratory facilities and a R&D group, we work together with our customers to solve issues, improve processes and eliminate waste.

We have created a set of Technical Information sheets and posters covering a wide variety of subjects which are invaluable to the modern foundry. TI sheets can be obtained from this site and ask your local Elkem representative about our very popular structure and defect posters. Below you can access some examples of technical advice from Elkem. 

Casting weight and thickness

We have a range of alloys to provide the optimum treatment for your castings, whatever the weight and section thickness.

Mechanical properties

You can achieve lower weight and higher performance in your cast iron by producing solution strengthened ferritic ductile iron (SSF). Elkem can advise on chemistry, treatment and inoculation methods for the successful production of these new grades of iron.

Reproducibility and consistency

We recommend taking corrective actions at an early stage of the process and using a portable, affordable thermal analysis system such as Elkem’s Epic TM . This can reduce scrap and save time and money downstream of the furnace.

Scrap rate

We helped many of our clients who had to deal with high scrap rates. You can also benefit from our experience.


Optimising chemistry, temperature and sand conditions and using the right nodulariser / inoculant package helps to reduce shrink by maximising the effect of graphite expansion.

Surface defects

Titanium, aluminium and moisture are the common causes of hydrogen pinholes in greensand systems. Both Al and Ti lower the surface tension in the liquid iron. This allows gasses to be picked up more easily.
