ABSTRACT
Copper is a unique material. It has excellent electrical and thermal conductivity, and it is malleable and machinable. However, it has low mechanical properties and must be cold worked or alloyed to obtain strength. Copper is classed as a noble metal and is, therefore, corrosion-resistant. It is resistant to urban, marine, and industrial atmospheres and finds use as sheeting, roofing, and the like, in these environments. It is resistant to water and finds use in domestic and industrial systems and in seawater applications.
