Description
Copper (Cu) is the 29th chemical element in the periodic table. This metal is softer than iron, but harder than zinc. It is a reddish-closured metal with a metallic transition lustre that is part of the so-called copper family along with gold and silver. The differences between copper and bronze, although seemingly very similar, are significant and it is necessary to be able to distinguish between the two. When joined with other elements in alloys, its mechanical characteristics are improved, but its conductivity is reduced. There are many copper alloys which, depending on their composition, have different characteristics. The main alloys are bronze and brass.
