A Timeline of Copper Technologies

[Copper](https://en.wikipedia.org/wiki/Copper) and [copper alloys](https://www.copper.org/publications/pub_list/pdf/a1360.pdf) have been used in thousands of [products](https://www.copper.org/applications/), from [antiquity](https://en.wikipedia.org/wiki/Ancient_history) to the 21st century, all around the world. Prior to the mid-19th century, copper was used mainly for its [mechanical properties](http://copperalliance.org.uk/copper-and-its-alloys/properties/mechanical-properties): malleability, workability and castability. Since the late 19th century, copper’s role expanded immensely due to its extraordinary [electrical and thermal conductivity](http://copperalliance.org.uk/education-and-careers/education-resources/copper-properties-and-applications) properties. ;xNLx;;xNLx;In the 21st century, copper remains at the forefront in new and emerging markets, such as [antimicrobial products](https://en.wikipedia.org/wiki/Antimicrobial_copper-alloy_touch_surfaces#Antimicrobial_copper_products), [aquaculture pens](https://en.wikipedia.org/wiki/Copper_alloys_in_aquaculture), [electronic components](https://www.copper.org/publications/newsletters/innovations/2000/01/speeding_up.html), [renewable energy](https://en.wikipedia.org/wiki/Copper_in_renewable_energy), [heat exchangers](https://en.wikipedia.org/wiki/Copper_in_heat_exchangers) and [information and telecommunications](https://www.copper.org/applications/telecomm/) technologies. ;xNLx;;xNLx;(Viewers: Toggle the 2d/3d icon at the bottom left of your screen to alternate the view from 2-D to a very dramatic 3-D.
