The normal phase of copper is a solid metal. Copper is unusual among metals in that it has a trademark, reddish-gold color while nearly every other metal is silver or gray.
Copper is famous for its ability to conduct both heat and electricity. Only silver is a better conductor. It is also prized for its ability to be beaten into very thin sheets and to be drawn into thin wire. The first property is malleability, while the second is ductility.
One drawback of copper is that it's a soft metal and is stronger when it's alloyed with other metals such as tin and zinc.
