Wrought iron • is a very pure form of commercial iron, having a very small carbon content. It is tough, malleable (easily forming), ductile and can be easily welded. However, it is too soft to make blades from; steel, with a carbon content between wrought and the high-carbon brittle cast iron, is used for that.
