Wrought iron is an iron alloy with a very low carbon content less than 0.08 in contrast to that of cast iron 2.It is a semi-fused mass of iron with fibrous slag inclusions up to 2 by weight, which gives it a grain resembling wood that is visible when it is etched or bent to the point of failure.Wrought iron is tough, malleable, ductile, corrosion-resistant and easily welded.
