🔶Origins & milestones

Copper · The first industrial conductor — wiring, heat exchangers, roofs that go green.

Copper did not arrive as a finished commodity. Chalcolithic / industrial electrorefining 1860s around Cyprus / global still explains who makes it and which tests it sits in.

Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.

Where it began

Chalcolithic / industrial electrorefining 1860sCyprus / global

Timeline

c. 5000 BCENative copper

Hammered native copper in the Balkans and Near East precedes true smelting.

c. 3500 BCEBronze age

Tin bronzes raised hardness for tools and weapons.

c. 2500 BCECyprus mines

The island’s name is entangled with the metal’s European word-hoard.

1660sFalun / Cornish

Early modern European mining scaled sheet and coinage.

1865Electrorefining

James Elkington’s electrorefining made 99.9% Cu for telegraphy.

1870sEdison / Siemens wiring

Buildings and grids became copper-shaped.

1913IACS

Annealed copper defined the conductivity standard.

1982US penny zinc

Coinage debased; plumbing and wire stayed copper.

2000sData-centre busbars

High-current DC and EV inverters revived thick copper.

2020sCu crunch talk

Grid and EV forecasts collide with mine permitting, not with chemistry.
