Lamellar cast iron

LAMELLAR GRAPHITE CAST IRON

Fonderia Quaglia & Colombo of Legnano, Province of Milan, also produces high-quality lamellar graphite cast iron, also known as grey cast iron: this is an iron-carbon alloy in which the free carbon is present in lamellar form. Its mechanical properties depend on the structure of the matrix and the shape, size and distribution of the graphite.

The positive mechanical properties of lamellar graphite cast iron, such as its resistance to compression, shear stress and wear, its rigidity and vibration damping capacity, as well as its excellent workability, help make it a material which, if properly used, provides designers with optimal solutions to design problems.

To contact the staff at Fonderia Quaglia & Colombo and request information about the production of this alloy, or any other services provided by our Legnano foundry, simply fill out the form in the “Contacts” section on our site, or call (+39) 0331 402473 during office hours: Monday to Friday from 9.00 to 13.00 and from 14.00 to 18.00.
