Cast Iron

High-Silicon Cast Irons. Whereas standard ductile cast irons contain approximately 1.8% to 2.8% silicon, modified ductile cast irons typically contain 3.5% silicon. High-silicon cast iron contains silicon in the range of 14.20% to 14.75%. Silicon cast iron has excellent resistance to corrosion, especially in sulphuric acid (H 2 SO 4) environments, in all concentrations to 100% up to the

What Is Wrought Iron?

Wrought iron is a relatively pure iron alloy, with a much lower carbon content than cast iron. However, it has a small amount of slag added to it during the manufacturing process. Slag is the waste left over when pure iron is extracted from its ore. It is a mixture of silicon, sulphur and metal oxides that gives wrought iron some unique properties.
