What Is Wrought Iron? Why Are Bird Cages Made From It?
 From Wikipedia, the free encyclopedia.
Wrought iron is a very pure form of commercial iron, having a very small carbon content. It is tough, malleable, ductile and can be easily welded. However, it is too soft to make blades and swords. When formed into bars, it is known as “bar iron”. Wrought iron has been used for thousands of years, and represents the “iron” that is referred to throughout history.
