Cast iron is produced by smelting iron-carbon alloys that have a carbon content greater than 2%. After smelting, the metal is poured into a mold. The primary difference in production between wrought iron and cast iron is that cast iron is not worked with hammers and tools.

The mould is usually realized by steel or cast iron and it represent the negative shape of the final component. Inside the mould the metal is poured by gravity, contrarily to the die casting process where the metal is forcibly injected inside the mould. This process is usually used for high-volume of small, with uniform wall thickness.

Cast iron that has not cooled evenly produces a low-quality cast. Other problems faced during the cast iron process include contamination of the iron, gas porosity (the forming of bubbles in the iron), and problems with the fluidity of the metal. The casting process is an art that must be examined and experienced to be fully understood.

Answer (1 of 3): The difference between cast iron and steel is basically the % silicon and % carbon. Cast iron has typically 1% to 3% silicon and 2.5% to 4.0% carbon. Steel is much more flexible and ductile than cast iron because of the lower carbon and silicon. Both silicon and carbon are "hardn...
