Cast iron according to its structure and performance characteristics

Gray cast iron: has good strength and wear resistance, suitable for manufacturing a variety of castings.

Malleable cast iron: With good plasticity and toughness, it is suitable for manufacturing parts that need to withstand shock and vibration.

Vermicular graphite cast iron: with high tensile strength and elongation, suitable for the manufacture of high strength castings.

Ductile iron: with high strength and good plasticity, it is suitable for manufacturing castings with large cross sections.

Different types of cast iron have obvious differences in organization and performance

Gray cast iron: The graphite in the structure is distributed in sheets, with high strength and wear resistance.

Malleable cast iron: the graphite in the structure is distributed in clumps, and has good plasticity and toughness.

Vermicular graphite cast iron: The graphite in the structure is distributed in vermicular shape, with high tensile strength and elongation.

Ductile iron: The graphite in the structure is spherical distribution, with high strength and good plasticity.
