Copper Specifications
Copper: A Vital Element of UK Industry
In the modern economy, copper emerges as a vital thread through diverse sectors. Its exceptional electrical conductivity renders it indispensable to the electronics and power industries, where it forms the lifeblood of circuitry and power transmission.
Moreover, copper's thermal conductivity and malleability underpin its pivotal role in construction, where it facilitates efficient heating and cooling systems and is the material of choice for many architectural wonders.
Copper as a Barometer of Economic Trends
Widely regarded as an indicator of economic health, the demand for copper, driven by its ubiquity in infrastructure and manufacturing, has earned it the moniker of "Dr. Copper."
Its fluctuations in demand and price are closely monitored by economists and analysts worldwide as a reflection of broader economic trends.
Copper and Copper Alloy Specifications
Copper is a medium strength, non-magnetic metal. It has excellent electrical and thermal conductivity properties and has a comparatively low cost. In its purest form it is soft and malleable but the introduction of alloying elements provides many industrial and commercial uses.
Holme Dodsworth’s extensive range of copper product types includes a variety of copper alloys which have a high level of corrosion resistance that makes them ideal for the production of everything from valves and pipe fittings to architectural extrusions. As a good conductor copper is the metal of choice for the manufacture of electrical busbars for the switchgear industry as well as wire for printed circuit boards.
Other uses include domestic cookware and various bio-medical applications.
