Wrought iron is an iron alloy with a very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure.

The puddling process, patented in 1784, was a relatively low cost method for producing a structural grade wrought iron. Puddled wrought iron was a much better structural material, and was preferred for bridges, rails, ships and building beams, and was often used in combination with cast iron, which was better in compression.
