Wrought Iron
Wrought Iron
Commercially pure iron, contains low carbon content and often appears to have grains resembling wood. Usually larger items which are produced for support as these items cannot be brittle. Examples are architectural nails, beams, anchors and personal items.
Cast Iron
Contains 95% carbon, and larger amounts of silicon and phosphorus. Has a very low melting point allowing it to be “cast” into objects using molds of various sorts. Often used for objects which tend to be less weight bearing or supportive such as cooking pots, cannon balls and architectural hinges.
Steel
Mostly iron with a small amount of carbon and other alloying minerals; Usually contains 1-3% slag content. Steel objects vary in size, complexity and function.
