Properties
Lamellar iron, more commonly known as grey iron, is suited to the production of parts with no particular mechanical requirements.
Being easy to produce, with very good machining and casting properties it is now widely used in all sectors.

Properties
Vermicular graphite cast iron stands between lamellar and spheroidal graphite in the family of cast irons.
Its properties, especially good thermal conductivity and elongation make it suitable for parts with low mechanical stresses such as electrical motor housings.
