Properties: An Introduction to Copper

Copper is tough and ductile, but is valuable due its ability to conduct electricity. While it is suited to many applications most centre around its excellent electrical conductivity (e.g. busbars and electric wire). Other uses utilise its corrosion resistance (e.g. water pipes and heat exchangers).
