Introduction

Copper and copper alloys meet the challenges of modern life in many ways. Often seen in plumbing systems and good quality roofing and cladding, they are also frequently unseen providing essential services inside equipment in houses, offices, commercial and industrial buildings. They are amongst the most necessary materials needed to provide the means to keep home, commerce and industry running.

Main uses of copper

Electrical Applications
Approximately 65% of copper produced is used for electrical applications. Copper has the highest electrical conductivity of any metal, apart from silver, leading to applications in:

• Power generation and transmission - generators, transformers, motors, busbars and cables provide and deliver electricity safely and efficiently to homes and businesses.
• Electrical equipment - providing circuitry, wiring and contacts for PCs, TVs and mobile phones.

Copper has a key role to play in energy efficiency - the judicious use of 1 tonne of copper in the energy sector makes it possible to reduce CO₂ emissions by 200 tonnes per year on average.

Construction
25% of all the copper produced is used in buildings - for plumbing, roofing and cladding. Copper provides light, durable maintenance-free structures that are naturally good looking, long lasting and fully recyclable. Copper's naturally antimicrobial properties can be exploited in hygienic surfaces for hospitals and healthcare facilities.

Transport
Trains, trams, cars and lorries all need copper and transport accounts for 7% of copper usage. The high purity copper wire harness system carries the current from the battery throughout the vehicle to equipment such as lights, central locking, on-board computers and satellite navigation systems. Electric super trams in cities such as Manchester, Sheffield and Croydon, provide clean, efficient transport powered by electric motors. The overhead contact wires are either copper-silver or copper-cadmium alloys.

Other
The remaining 3% is used for coins, sculptures, musical instruments and cookware.
