Materials
Gray cast with lamellar graphiteGray cast with lamellar graphite is distinguished by its good compressive strength, muffling ability, machinability, castability and low cost.
Gray cast with spheroidal graphite
Gray cast with spheroidal graphite combines the advantages of cast iron and gray cast with lamellar graphite. In gray cast with spheroidal graphite the graphite extracts itself in the shape of spheroids and therefore the tensile strength and tenacity are increased, because this graphite form has a smaller incising affect in the metal matrix.
