Metal has been a part of our lives since the dawn of the Bronze Age. It's discovery and development over the years has made an incalculable contribution to civilization in everything from hunting to building to decoration. Most of us can tell the difference between aluminum and copper or brass. Steel and similar-looking metals have proven to be very durable and versatile, but it's difficult to tell one from another, or to tell apart different alloys. One easy example is the difference between cast iron and wrought iron. Generally, they look the same, and one is known mostly for cookware while the other is recognized mostly for its decorative qualities. There is a distinct difference between the two, and it has nothing to do with when they were discovered or their usage, though their use is based, in part, on their method of production.
The difference is in how they're crafted. Wrought iron is heated and then shaped using metal-working tools, cast iron is melted and then poured into molds to create the finished product. Wrought iron is more pure and stronger, due to the working process. Cast iron products are brittle and contain more impurities in the metal, but the ability to mold cast iron gives the finished products a more uniform and accurate appearance. That makes it perfect to use in mass-produced items, like frying pans.
You can find steel suppliers and sources for other metals by doing a quick online search. It should be easy to find local supply shops or online suppliers that have a wide variety of metals from all over the world and easy online payment and delivery options.
