Copper Single Crystals and Substrates
Copper is a reddish metal, malleable and ductile, with high electrical conductivity, making it ideal for electrical wiring, its most important commercial use. Coppers electrical conductivity is second only to that of silver. Historically copper has been important as one of the first worked metals, especially as the alloy bronze. It is still used in coins.
