Bronze is amongst one of the first alloy metals that was developed and is a mixture of copper and tin with copper being the predominant metal. Combining the two metals makes Bronze stronger than either of copper of tin on their own. Other metals can also be added to the mix and include aluminium, nickel, zinc and various other materials.

Bronze is thought to have been used as far back as Egyptian times and some of the earliest Bronze artefacts have been found in the areas of China and the Middle East. The metal’s name was attributed to the Bronze Age era due to the wide spread use of the metal in items that were used throughout all of society.
